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!
Io.
No question about it: Io. And I don’t think any probe got that close up and personal with it except Galileo, so there.
Yep, I saw IO too.
Just in case, I’ll go with Voyager 1 🙂
The picture is grainy enough to be a zoom in on a print.
Somewhere on Io, an I’ll guess it’s by Voyager.
*and
It looks like Io. The craft is either the Voyagers or Galileo.
LC
Craft either New Horizons or Helios II and its our sun ??
Totally Io, and I’ll guess Voyager 1.
there is a surface of Io, undoubtedly
on the right side of that picture, from top to bottom, we can see one of the most active volcanoes – Prometheus. Lower – caldera, called Culann Patera, and a little more lower – one of the highest mountains on this satellite – Tohil Mons
Io is a wonderful creature of Nature! 🙂
and, i think, this picture was constructed from images of Galileo and Voyager
Io was photographed by Voyagers 1 and 2 so I am going to guess Voyager 2 because they knew what they wanted to see in more detail and it’s b&w
SteveZodiac, in that case: “they knew what they wanted to see in more detail” while working with Galileo and New Horizons. after Voyagers
Nevertheless, Voyager 2 is more correctly in your answer
Io. There’s nowhere else with that many volcanoes. Sooo close! I’ll go with Galileo.
