This post is going to serve double duty. First of all, I forgot to mention that the answer for last week’s WITU Challenge has been posted, so if you are wondering if it was either some sort of blobby nebula or a Klingon Bird of Prey decloaking, (thanks, IVAN3MAN) you can find the answer on last week’s WITU post.
Now, for this week, take a look at the image above and see if you can name where in the Universe this image is from. Give yourself extra points if you can name the spacecraft responsible for the image. We provide the image today, but won’t reveal the answer until later. This gives you a chance to mull over the image and provide your answer/guess in the comment section. Please, no links or extensive explanations of what you think this is — give everyone the chance to guess.
UPDATE: The answer has now been posted below.
This is Jupiter’s moon Io, as seen by the Galileo spacecraft. This mosaic is made up of 32 monochrome images take by Galileo’s imaging system which had spatial resolutions up to 1 km/pixel. Learn more about this image here.
And check back next week for another test of your visual knowledge of the cosmos!
