Imagers capture solar system targets

See all the entries of the 2009 Astroimaging Contest in the Solar System category.
Jupiter, Ganymede, and Io
Jupiter and its satellites Ganymede (left) and Io show lots of detail in this composite image. The photographer took a brief movie through red, green, and blue filters and selected about 1,000 frames from each color to combine to form the final image. To the lower right, orange Io casts its shadow onto Jupiter's cloud tops.

Astronomy's 2009 Astroimaging Contest was a resounding success. You can see all the winning submissions and read more about them in the September issue of Astronomy magazine. But we didn't have enough pages to print all the images we received, so we're putting them all up on the website.
