Times Square from Space

2012 is nearly over and soon hoards of people (this news account estimates attendance will be a staggering one million people) will gather in Times Square in New York City's Midtown Manhattan to watch the time ball drop at the stroke of midnight as they celebrate the passage of time. It is the world's biggest annual party.

The time ball marks 2012 in Times Square

Of course, in Times Square it is a party every night. I had the chance last fall to make my first visit.  I wasn't surprised at how bright it was, but as someone who likes peace and quiet and also advocates for light pollution controls, it was a bit of a shock to my system.

It is a 24/7 display of giant electronic TV's, excessive lighting and more. There certainly is a place for this kind of thing in a few places across the globe but the Times Square ambiance, with over the top lighting and advertising, is a far cry from what most cities need or would want. There currently is a lot of pressure from the billboard industry to bring this kind of advertising to many communities across the U.S. but some groups like Ban Billboard Blight are opposing this.

The lighting in Times Square isn't limited to giant video screens. The buildings themselves are generally illuminated too from within and without. 

Lights like this one at left shine upward to illuminate buildings.

Up light like what is shown above is illegal in communities that have controls on outdoor lighting. I wont argue the "need" for this, but a lot of this light completely misses the target shining up into the sky and not on the buildings at all.

All of this light (from the advertising too) adds up to a lot of light going upwards, which makes Manhattan easy to spot from space at night.

The Expedition 16 crew of the International Space Station captured the above image of Manhattan and the surrounding area the night of February 10, 2008. Can you spot it?

Let's zoom in a bit:

The dark area just left of center is the Hudson River and the one at right is the East River.  The dark rectangle near the top is Central Park.  The bright area beneath it is Manhattan and Times Square.  Compare its brightness to just about everything else in the wide image.  Of course, Times Square is all about excess that's why a million people will be there tomorrow night.

Star Trek: The Corbomite Maneuver

The first episode of the original series of Star Trek produced after the 2 pilot episodes was The Corbomite Maneuver.

Lt. Uhura, Yeoman Rand and Dr. McCoy make their series debut. McCoy's character really makes a mark here as he ignores a red alert to finish a physical on Kirk, is quick to pour drinks with Kirk, challenges Kirk's decisions and more. The writers gave Deforest Kelly some real material to work with here and he did a fine job jumping into the character. While some Trek characters like Spock evolve over time, the audience knows McCoy right away.

Spock, Scotty, Uhura (in gold!), McCoy, Kirk, a random Red Shirt & Sulu

Just about the only thing that Uhura does is say "Hailing frequencies open, sir." I am guessing here (I didn't actually count them), but she says this nearly dozen times in just this one episode. Perhaps that is why in a future episode she says "sometimes I think if I hear that word frequency once more, I'll cry."

There's plenty here for Kirk, Spock and even Sulu to do react to in the episode. Anthony Call guest stars as the navigator Lt. Bailey, who is overwhelmed by the circumstances. In the episode the Enterprise encounters a rotating Rubik's cube, "some kind of space buoy".

After it blocks their path and emits harmful radiation they destroy the cube only to encounter the Fesarius, a ship that Spock says is nearly a mile in diameter.

The ship's commander, Balok (above, right) threatens to destroy the Enterprise. Kirk counters the threat with a bluff, saying that the Enterprise is carrying Corbomite,  "a material and a device which prevents attack on us. If any destructive energy touches our vessel, a reverse reaction of equal strength is created, destroying the attacker."  He adds, "since the initial use of corbomite more than two of our centuries ago, no attacking vessel has survived the attempt."

The bluff works, Balok backs off in destroying the Enterprise only to launch a small ship that takes it in tow toward a planet of the First Federation.

Naturally, the Enterprise manages to break free, but Balok's ship is damaged in the process.  Everyone (even Spock!) is surprised when Kirk turns the ship around to the damaged vessel and offers aid. Here's how that plays out:

Uhura: A signal, Captain. It's very weak. It's Balok. It's a distress signal to the Fesarius. His engines are out. His life-sustaining system isn't operating. The message is repeating, sir.
Kirk: Any reply?
Uhura: Negative. The signal is growing weak. Sir, I doubt if the mother ship could have heard it.
Kirk: Plot a course for it, Mister Bailey.
Spock: For it, Captain?
Kirk: Dead ahead. [Addressing the crew] This is the Captain speaking. The First Federation vessel is in distress. We're preparing to board it. There are lives at stake. By our standards, alien life but lives nevertheless. Captain out.
Bailey: Course plotted and laid in, sir.
Kirk: Mister Scott, ready the transporter room.
Scott: Aye, sir. (leaves)
Kirk: Mister Sulu, bring us to within one hundred metres. Ahead slow.
Sulu: Ahead slow, sir.
McCoy: Jim, don't you think
Kirk: What's the mission of this vessel, Doctor? To seek out and contact alien life, and an opportunity to demonstrate what our high-sounding words mean. (Addressing everyone on the bridge) Any questions?

This is where Star Trek shines. They stop to render aid to aliens who referred to them as "primitive and savage," who then threatened to kill them. The classic response would be to strike at them while they are down, right? But Kirk and Trek show just what humans of the future are and how we all should be today. It is moments like this one that that make this show special and why I keep going back to Trek.

It ultimately turns out the Balok was simply testing them and not at all what anyone suspected. The image of Balok that they saw as no more than a puppet.

It is Clint Howard as the real Balok

Composer Fred Steiner, in his Star Trek debut, wrote just over 7 minutes of music for this episode. The rest was music that was tracked from other episodes. His score first gives a real sense of both the rotation and the danger represented by the space buoy (check out a preview of "Space Cube/Condition Alert"  from La-La Land Records) before then taking on the danger of Balok and the Fesarius. While there isn't much of Fred Steiner's music here, it is good stuff. Fortunately, Steiner returned to provide the music for more episodes.

If you haven't seen The Corbomite Maneuver in a while, track it down and give it another watch. It is worth your time. Next up, Mudd's Women.

Happy Xmas (War is Over)

Here it is, my favorite Christmas song:

I hope you have a very merry Christmas and a happy New Year.
Let's hope it's a good one without any fear.

Star Trek: Where No Man Has Gone Before

Star Trek's second pilot episode, Where No Man Has Gone Before can be summarized with the following quote:

"Power tends to corrupt, and absolute power corrupts absolutely." - John Emerich Edward Dalberg Acton, 1887

The pilot, which follows The Cage, has only one returning cast member - Leonard Nimoy as Mr. Spock. The episode introduces the character of Captain Kirk. Mr. Sulu and Scotty also make their first appearance.

Dr. McCoy is yet to appear in the show even though Star Trek creator Gene Roddenberry cast a doctor in each of the two pilot episodes. The Cage featured Dr. Boyce who was very nicely played by John Hoyt. Where No Man Has Gone Before features the lifeless Dr. Piper (played by Paul Fix).

Sulu, Scotty, and the lifeless Dr. Piper

It is amazing that Dr. Piper is given so little to do here, especially since there is major medical trauma to a major character. Ultimately all of Trekdom is probably better off that almost all of the medical stuff was given to guest star Sally Kellerman who did a fine job playing psychiatrist Dr. Elizabeth Dehner. Since she does not survive the episode it paves the way for Dr. McCoy to come on as a regular when the series is launched.

Which brings us to the plot. The Enterprise recovers a badly damaged recorder from the S.S. Valiant, a ship that went missing almost 200 years ago. Spock reveals that the Valiant was swept off course and out of the galaxy. The ship encountered an unknown force. Its crew was desperately seeking information on ESP before the captain gave an order to destroy the ship.

 Kirk decides that other ships will be heading this way someday so the Enterprise should head out of the galaxy. Strangely enough (at least by actual science) the Milky Way has some sort of energy barrier on its outer edge. Sure enough they encounter the same phenomenon. Helmsman Gary Mitchell and Dr. Dehner are zapped by the effect and Mitchell is transformed and developing new powers.

The Enterprise is badly damaged and makes for the planet Delta Vega which has an automated lithium cracking facility. There they hope to maroon Mitchell before he grows too powerful to cope with.

Here is a passage of dialog from on Delta Vega that helps to define Spock for the audience as an emotionless alien being:

Kirk: Doctor Dehner feels he [Mitchell] isn't that dangerous. What makes you right and a trained psychiatrist wrong? 

Spock: Because she feels. I don't. All I know is logic. In my opinion we'll be lucky if we can repair this ship and get away in time.

It is just one of a few exchanges in the episode that brings out Spock and what he is all about.

Before there were Red Shirts, there was Lt. Kelso

The Enterprise is repaired but before they can flee Mitchell uses kills powers to kill Lt. Kelso and escapes. Mitchell brings Dehner along and gives powers to her as well.

Kirk pursues Mitchell and in for the first time (don't worry, folks it wont be the last) unleashes an argument about humanity, wisdom, etc. in an attempt to convince Dr. Dehner to help him.

Kirk: What will Mitchell learn in getting there? Will he know what to do with his power? Will he acquire the wisdom?

Dehner: Please go back while you still can.

Kirk: Did you hear him joke about compassion? Above all else, a god needs compassion.

Dehner: What do you know about gods?

Kirk: Then let's talk about humans, about our frailties. As powerful as he gets, he'll have all that inside him.

Dehner: Go back.

Kirk: You were a psychiatrist once. You know the ugly, savage things we all keep buried, that none of us dare expose. But he'll dare. Who's to stop him? He doesn't need to care. Be a psychiatrist for one minute longer. What do you see happening to him? What's your prognosis, Doctor?

Mitchell returns and Dehner turns on him. Que the Force lightning:

The episode works and lays the foundation of a lot of Trek to come. We get a basic understanding of both Kirk (see dialog above) and Spock and fine performances all around from the players who matter.

Alexander Courage scored this episode. The music for the episode, along with all the music for the original series, is available on the massive 15-CD release by La-La Land Records. There's nearly 28 minutes of music for this episode. You can get a preview of one track, "Power Mad/Situation Grave/Epilog", from this episode here. His music here give a sense of emptiness and longing for deep space as well as solid action cues for the, well, action. It is a great score - working well both in the episode and standing on its own on the CD.

As the second pilot to Star Trek, Where No Man Has Gone Before, successfully launch of what ultimately became a huge SF franchise in TV, movies, novels and more. If you haven't watched it in a while, go back and re-discover this early episode of Trek. 

Next up here on Visible Suns will be The Corbomite Maneuver.

Support the IDA!

Just a short post today. Take a look at this short video (with me narrating) about the International Dark-Sky Association.

For those that are interested the next Star Trek review, Where No Man Has Gone Before, will be posted this weekend.

Celestial Holiday Treats!

The solstice is almost here and it is time for some holiday treats.

First up is this amazing image of Saturn from the Cassini imaging team:

The image was taken from within Saturn's shadow looking back toward the sun. This does not show Saturn in "true color", but rather the color is enhanced here.  Read all about the image here.

The next treat comes from the Spitzer Space Telescope:

It is an infrared image showing the star known as Zeta Ophiuchi and a cloud of dust. Stellar winds are creating a sort of bow shock in the dust cloud as the star moves through space. Like all infrared images, this one is false color too as we can't see infrared light.  Read more about it here.

Beautiful, aren't they?

Star Trek: The Cage

As promised, I am starting to review both the episodes and the music of the original Star Trek series in production order beginning with The Cage, the first pilot episode. As an aside, I know that the entire series has been "remastered" with new effects and other visuals - many of those changes have radically altered the look of the show. In the reviews I am writing, I'll be using the DVD release of the series as my reference.

The Cage never aired during the first run of the series, but much of it was incorporated into a two part-episode that appeared later in the series. It really is a great introduction to Trek and a first rate science fiction story in its own right.

The look and feel of the ship, the crew and their gadgets is a bit different from what was to come later in the series, yet the basic elements are there.

That's the Pinwheel Galaxy (M101) on the wall of the transporter room.

 The shot of the transporter room shows the start of the racial harmony for which the show became famous. For me a large part of the appeal of the show was the positive message for the future. (Of course, the flying through space part is also a big draw.) Star Trek shows us that is it possible for humans to work through our problems and grow up. Decades after its inception there are still times when we all need to be reminded that a better future lies ahead.

The story follows the crew of the Enterprise under the command of Christopher Pike as they look for survivors of a spaceship, the S.S. Columbia, which went missing in the Talos Star Group some 18 years prior.

Apparently the Talos Star Group is none other than the Pleiades (also known as the Seven Sisters), a group of stars that is easily visible in the nighttime sky here on Earth. The crew tracks down metal wreckage on the world known as Talos IV, which you aren't supposed to notice is really the Moon.

Talos IV (left), the Moon (right)

Pike and the crew find the survivors - a "collection of aging scientists" and Vina, who was apparently born as they crashed.

Unbeknownst to Pike and the crew, none of this is real. The crash site is a fake and Pike is imprisoned by the Talosians. We learn later that the Talosians live underground because the surface of their world was decimated by war. The Talosians have developed great mental powers and can create realistic illusions.

Pike, always with Vina, is taken through a series of illusions - places and events from his past as the Talosians enjoy the show. As Vina explains "You're better than the theater to them. They create an illusion for you. They watch you react, feel your emotions."

One of the illusions takes Pike back to Rigel VII - a planet where Pike had a "recent death struggle."  Nice view, if you can get it. Seriously, who wouldn't want to live in a castle with that view out the window? Unfortunately this big ugly guy ruins the experience:

Pike defeats him, rescues Vina. They are taken to other fantasies: a nice domestic picnic and the famous palace scene where Pike and others are watching Vina dance in the guise of a green Orion slave girl:

Of course Pike isn't playing along and wants nothing to do with her or any fantasy that the Talosians create for him. Vina later explains the problem with how the Talosians are living:

"Because when dreams become more important than reality, you give up travel, building, creating. You even forget how to repair the machines left behind by your ancestors. You just sit, living and reliving other lives left behind in the thought record."

Ultimately Pike manages to break free and the Talosians are convinced that holding humans captive isn't a good idea because they are "too violent and dangerous a species" for their needs. Pike and two others later brought down are free to go.  But what of Vina?

Vina wasn't really born at the time of the crash. She was a badly injured survivor. The Talosians had no medical guide for putting her back together. Vina chooses to remain with the Talosians as they give her the illusion of health, beauty and even the company of Pike.

And they fly off for another adventure:

All of this works not only because of performances given by the actors and the technical crew, but also because of the masterful musical score written by Alexander Courage. Courage wrote just over 32 minutes of music for the episode. In it he created not only the iconic Star Trek musical theme but also two themes that are used often here - one for the Talosians and one for Vina.

The theme for the Talosians is a played on an electronic guitar giving an undeniably creepy vibe for the aliens. You can hear a sample of it here.

Vina's theme is used in a variety of ways. It is at times haunting and longing. It is also used as the pulsing theme as Vina dances as an Orion slave girl. Play the clip below and you'll hear it used for both the quiet picnic scene and then as she dances.

All-in-all the score works very well. Courage's music for this first episode of Star Trek sets the tone (get it?) for what is to follow in the entire series and it listens well in isolation too.

Boldly Going

It is time for me to start posting more often on this blog and expand its content a bit. Two of my interests beyond astronomy are reading/watching science fiction and listening to movie soundtracks.

My interest in music started somewhere around the time that Flandrau Planetarium opened to the public in 1975. They used to give out a list of what music was used in their shows and I started tracking down the various pieces of classical music that had been incorporated into the shows. By 1977 the soundtrack to Star Wars by John Williams came on the scene and for me there was no turning back.

Early influences in getting me into science fiction were the Apollo Moon landings; my 5th grade teacher, who read aloud Robert Heinlein's Red Planet and Have Spacesuit--Will Travel; and the original Star Trek TV series. I have been watching Star Trek for so long, that I have no memory of seeing any of the 79 episodes for the first time. They have just always been there.

Given my interest in movie soundtracks, I guess it should be of no surprise that I had to order this massive 15-cd box set of music from the original Star Trek released by La-La Land Records that just came out. The limited edition set contains all of the music recorded for the series - some of it was never even used.

The set arrived here at Visible Suns earlier this week and I thought that it might be fun to work my way through both re-watching the episodes and listening to the music while posting reviews of each here on the blog.

I will still be posting cool things about astronomy, the war on light pollution and the like, but I hope that this expansion will be enjoyable for those that visit the blog.

Look for a review of the first pilot for Star Trek, The Cage, to appear sometime this weekend.

Weather domes

I had the chance to go to Kitt Peak National Observatory today to prepare to install a night sky brightness meter. While on the roof of one of the buildings there I took this shot of the dome of the 84-inch (2.1 meter) telescope:

The view reminded me of one of my favorite old Palomar pics:

 I know, my shot doesn't really compare to the vintage one, but that's the best you'll get out of me today.

The Black Marble and GLOBE at Night

Did you happen to catch the "Black Marble" images that were released last week?

The images came from the Suomi National Polar-orbiting Partnership satellite and they represent our most detailed look at Earth at night. Chances are you'll be able to spot your home town in these new images wherever it happens to be.

Here's a look at the whole globe:

 Click here for a much higher resolution version from NASA

And here is much of North America:

Click here for a much higher resolution version from NASA

Most of this represents poorly directed, upward pointing light.  It is essentially wasted energy.

These images do not document sky glow - that brightening of the night sky that keeps most of us from seeing faint stars and other sky phenomena. The best way to study sky glow is to measure it from down here on the ground.  Thankfully it is easy to measure and document sky glow. A great and easy way for anyone to do so is to participate in the GLOBE at Night program. Be sure to check out their website to see how to get involved.  Their first 2013 campaign begins on January 3rd!

Night sky brightness measurements from GLOBE at Night and other programs are an essential tool in documenting light pollution and I urge you to get out there and make some measurements.

The Black Marble - not so black, is it?

Bill Nye Speaks Out Against Light Pollution

In September 2011 along with the IDA executive director I had the chance to meet Bill Nye over at the Planetary Society offices.

It should be no surprise that the night sky has been a source of inspiration for their members.  A beautiful, inspiring sky can help make you want to explore the universe. We talked about how the two organizations might work together and it led to my article that was the cover story for last summer's issue of The Planetary Report.

Another eventual result of that meeting what that Bill Nye recorded a short statement on light pollution.  Check it out:


 It is great to have one of the more famous, dare I say, Science Guys on the planet speak out about this issue.

Of course, before there was Bill Nye there was Carl Sagan (one of the co-founders of the Planetary Society). Sagan had a passage on light pollution in his book Pale Blue Dot. It was moving enough that I used the quote to begin my article and I present it now here:

Before we invented civilization, our ancestors lived mainly in the open, out under the sky. Before we devised artificial lights and atmospheric pollution and modern forms of nocturnal entertainment, we watched the stars. There were practical calendrical reasons, of course, but there was more to it than that. Even today, the most jaded city dweller can be unexpectedly moved upon encountering a clear night sky studded with thousands of twinkling stars. When it happens to me after all these years, it still takes my breath away.

Well said, don't you agree?

Dark Sky & Lighitng Videos

If you are looking for a series of short but informative videos on lighting and light pollution, you should follow The Dark Ranger on YouTube.  They are the work of Kevin Poe, a ranger in Bryce Canyon National Park.

I have embedded two of his videos below. At the recent annual general meeting of the International Dark-Sky Association, he was presented with a Dark Sky Defender award. In the first video he talks about getting the award and the lighting of a city I know quite well:

Now check out Urgings for a Globe Free Globe:

Coming up in the next post, another video on light pollution from a world-renowned science expert.

It is another commercial!  Okay, most of us have too many commercials in our lives, but I am sharing this one for Bing (I don't even use Bing) because it servers as another reminder that the night sky is an important part of our lives that we are starting to loose. Like in the commercial in the Billy post below, it shows that this message is starting to become a part of mainstream media.

I have a couple of other videos to share over the next few days, so if anyone is reading Visible Suns check back again soon.

India from Space at Night

In case you missed it, here is an amazing image of India from space at night.

The image, taken November 12 2012, was published on the NASA Earth Observatory site. The image shows the density of population there. The lights of more than 1.2 billion people are represented here. India has 30 cities with populations over 1 million - imagine how much energy could be conserved if the lights were retrofitted so as to not shine wastefully upward into space.

By the way cities in Bangladesh, Nepal, and Pakistan are also visible near the edges of the image.

There are several high-resolution download options on the NASA site that are worth checking out, including a Google Earth KML file.

Another Commercial (Sorry)

Back again, this time posting a commercial from a few years ago, again with an astronomical theme.

What do you think? Are there other astronomically-themed commercials out there that have caught your eye?

An Astronomy Themed Commecial

Gosh, has it really been since July? Sorry about that.  I will be blogging more soon about light pollution and other things on my mind.

Until then, check out this cool commercial from Dell: Meet Billy: The boy who captured the stars

Arthur C. Clarke on Light Pollution

I can't tell you how many of Arthur C. Clarke's books I have read. I have a dozen or so in my collection today, but have read many times that. His words took me far across the universe and back again many times. He was certainly one of the authors who helped to cement my love of astronomy, space and science fiction.

Back in 2001 Clarke recorded a short message of support for the International Dark-Sky Association (IDA) and its efforts to fight light pollution. I remember seeing a quote from it in an IDA newsletter when Clarke passed away in 2008.

Flash forward to 2012 where I am now working for the IDA. I was going through some old junk at the office, deciding what should be tossed and what should be kept when I ran across the Clarke video tape. After some effort finding a working VCR I confirmed that this indeed was the message that Clarke had recorded for IDA back in 2001 (a good year for it, don't you think?).

I didn't know if other copies of the tape had been made or not, but I knew that it had to be preserved and seen. I got it digitized and just recently had the chance to put it together and post it up for the world to see. So here it is:

I am happy to have found the tape and that I could help to get Sir Arthur's message out to the world.

The City Dark on PBS

An important (and award-winning) documentary called The City Dark will soon be shown nationally on PBS.  The target date for broadcast is Thursday, July 5 2012, but each station can essentially show it whenever they feel like doing so.  So be sure to check your local listings to find out when it will be shown in your area.

You can also watch The City Dark on your iPhone or iPad through the free PBS iOS app.

Filmmaker Ian Cheney recently appeared on CBS News to talk about the film. You can watch the interview below.

And here is the trailer for the film:

Washing One of Gemini's 8-meter Mirrors

It takes careful work to wash a telescope mirror, especially one that is 8.1 meters across and still installed in its telescope. Here is a cool video that shows off the process as it is done for the Gemini South telescope.

Two Steps Backwards for Dark Skies (and a pretty video)

The electronic billboard bill is now law in Arizona meaning that while the state's astronomical observatories are protected from their bright glow, the central and southwestern part of the state will now be no man's land.

The City of San Diego will now apparently be allowing "brighter outdoor lighting". According to this news report:

The report says the last changes, made in 2008, were overly influenced by astronomers and "dark sky advocates."

Sigh.  "Dark sky advocates".

In other news the winners of the 2012 Earth and Sky Photo Contest have been announced.   Follow the link to check out the beautiful photos of the night sky. A video of them is embedded below.  Maybe it will help to push the other news out of your mind. 

Electronic Billboards Again Threaten Arizona Skies

Several weeks ago Arizona made the news as Governor Jan Brewer vetoed legislation that would have allowed wide-spread use of electronic billboards in the state.  Well, there is a new measure advancing to do the same.  This time there are protections in place for the state's astronomical observatories but not for people living in the central and western portions of Arizona.

From Scenic Arizona earlier today:

Dear Billboard Watchers, Preventionists & Friends of Dark Skies:

The electronic billboard bill (see attached) came out of the partisan caucuses today in both the Senate and the House.  Final votes will likely occur tomorrow.  Please contact your senators and representatives and ask them to vote against the bill on Final Read.  You should be particularly strident if you live in any of the following counties/areas: Maricopa, Yuma, La Paz or the Apache Junction/Gold Canyon area of Pinal.  Electronic billboards would be (lawfully) allowed in these counties/areas for the first time since 1970 and the amended bill does not offer even the most basic protections that other states have enacted when they have rolled over for the billboard industry.  For example, in Texas electronic billboard panels facing the same direction on a roadway have to be at least 1500 feet apart for boards on both sides of the street.  In contrast, billboards on a state highway inside a municipality in Arizona would only have to be 100 feet apart on the same side of the roadway (e.g., Grand Avenue in Phoenix, Glendale, etc.).  Furthermore, the bill now includes an unnecessary emergency clause that would preclude citizens from exercising their constitutional right of referendum (is this even legal?) and would preclude cities and counties from adopting timely moratoria to get their local codes in order prior to the onslaught that is surely coming from the billboard industry (however, since the both ADOT and the Attorney General's Office are (incredibly or not so incredibly) refusing to follow the law and stop issuing permits for electronic billboards, there is a downside risk in opposing the emergency clause).

The amended bill is a result of an 11th hour deal between the major observatories and the billboard industry under heavy pressure from the latter.  The observatories did at least stick to their guns on keeping the prohibition in place outside of the county areas mentioned above.  Preserving that prohibition is at least a partial victory that we all should celebrate.  However, Scenic Arizona, the Neighborhood Coalition of Greater Phoenix, the Sierra Club and other active opponents of the bill were precluded from the negotiations and did not and could not endorse any compromise that does not offer at least some limitations on these monstrous and blinding eyesores that will proliferate in the allowed zone.  Even for those that live in the still protected zone, travel to and through the Phoenix area occurs often enough and we all must stand behind those that live in the allowed zone who are getting nothing meaningful out of the amended bill.

The House Member Roster is at: http://www.azleg.gov/MemberRoster.asp?Body=H.

Senate Members Roster: http://www.azleg.gov/MemberRoster.asp?Body=S

Beginning tomorrow morning, telephone calls are preferable to emails for brief communications (for those outside of the Phoenix area, note the toll-free number: 1-800-352-8404). Use email for more detailed messages. Make sure to indentify yourself as a constituent of the district.  If you don't know which district you are in, you can refer to http://www.azleg.gov/alisStaticPages/HowToContactMember.asp .

Which Cities Have Lighting Controls? You can Spot them from Space.

Yesterday I shared this picture on Facebook & via Twitter:

I guess it made at least somewhat of a splash because it ended up today in the San Diego Union Tribune newspaper.  My point was to show the city lights as a discussion point for light pollution, energy waste, etc. No mention of that made it into the paper, although the reporter did point out that I work for the International Dark-Sky Association.

For those who do not recognize the scene below the International Space Station, the coastlines of southwest California and Baja Mexico are visible as well as (from left to right along the coast) the city lights of Tijuana, San Diego and Orange County. The big city well inland is Phoenix, AZ (South is left of up in this view).

Here is another view that covers some of the same geography, but looking almost 180 degrees in a different direction and without the ISS taking up so much of the frame:

This time the Sea of Cortez is in the lower center, with Baja and the lights of the California cities on the left (North is left of up).  Also visible inland (from left to right) are Las Vegas, Phoenix and Tucson.  Here's an annotated version to help you find them:

You probably already know the answer to this, but which of these cities have lighting controls? Notice that the lights of Las Vegas look white - they have saturated that portion of the camera's electronic detector. Like everything in Las Vegas, its lights are also famous for being over the top.  The light polluting sky glow produced there is visible from hundreds of miles away and proves that what is illuminated in Vegas does not stay there.

The brightest city in Arizona, Phoenix, is bigger than Las Vegas. While it is a very large source of light pollution, notice that its core is not a intensely illuminated as that of Vegas.  Tucson is certainly bigger than Vegas, but it is much dimmer.  That's the result light pollution controls put in place there.  The latest revision of Tucson/Pima County Outdoor Lighting Code was put in place just last week and should help to keep Southern Arizona friendly for astronomy for some time to come.

Can you spot Flagstaff? It became the world's first International Dark-Sky City in 2001. It is smaller than Tucson and has even tighter lighting controls.  I believe that you'll find it just to the left of the "P" in Phoenix.

Coming back to California, can you tell which cities have lighting controls? Look at the LA & San Diego areas. There is a difference.
