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?

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