Earthshine is sunlight that has reflected from the Earth onto the dark side of the Moon and back again to Earth. Here ‘‘dark side’’ refers to that portion of the lunar surface that, at any instant, faces the Earth but does not face the Sun. Earthshine can be best seen during the crescent phases (the 1-5 day period before or after a New Moon). During this time the sun is mostly behind the moon from our perspective and bathing the Earth in a lot of direct light that is reflected onto the shadowed parts of the moon.

The World Outside My Window
Two years ago, film student David Peterson posted a time-lapse video montage to his YouTube page that was based on imagery of aurora and night lights captured by NASA astronauts. That video (All Alone in the Night) had racked up more than 6 million views by December 2013. On December 3, 2013, Peterson posted a new video (The World Outside my Window). His goal this time is to bring more attention to the station itself, including the humans aboard it, particularly astronaut Don Pettit. Pettit (seen below) appears in the video’s final shot and took many of the sequences used in the video.

Wow! It seems that some part of comet ISON survived the closest encounter with the Sun. I am very excited to see what has remained of the comet!
