Explanation: How many of these can you find in today's featured photograph: an
aurora, airglow, one of the oldest impact craters on the Earth, snow and ice,
stars, city lights, and part of the International Space Station? Most of these
can be identified by their distinctive colors. The aurora [4] here appears
green at the bottom, red at the top [5] , and is visible across the left of
image. Airglow [6]  appears orange and can be seen hovering over the curve of
the Earth [7] . The circular Manicouagan Crater [8]  in Canada [9] , about 100
kilometers across and 200 million years old, is visible toward the lower right
and is covered in white snow [10]  and ice. Stars [11] , light in color, dot
the dark background [12]  of space. City lights [13]  appear a bright yellow
and dot the landscape. Finally, across the top, part of the International
Space Station [14]  (ISS) appears mostly tan. The featured image [15]  was
taken from the ISS [16]  in 2012.
