Where In The Universe #64

It’s time once again for another Where In The Universe Challenge. Test your visual knowledge of the cosmos by naming where in the Universe this image was taken and give yourself extra points if you can name the spacecraft responsible for this picture. Post your guesses in the comments section, and check back later at this same post to find the answer. To make this challenge fun for everyone, please don’t include links or extensive explanations with your answer. Good luck!

UPDATE: The answer has now been posted below.

This is a false color picture of Callisto, taken by Voyager 2 on July 7, 1979 from about 1,094,666 kilometers (677,000 miles) away. The surface of Callisto is the most heavily battered and cratered of the Jupiter’s moons and resembles ancient heavily cratered terrains on the Moon, Mercury and Mars. The bright areas are ejecta thrown out by relatively young impact craters. A large ringed structure, probably an impact basin, is shown in the upper left part of the picture.

How’d you do?

Check back next week for another WITU Challenge!

    This should be photo of Calisto by the Galileo spacecraft

  2. Jorge says

    This is Jupiter’s moon Callisto. The picture strikes me as something one of the Voyagers would come up with as it flew by the jovian system.

  3. Lawrence B. Crowell says

    Definately Callisto. Looks like we got an easy one this week. I would say this is from the Galileo spacecraft.


  4. Nereid says

    Callisto, by Galileo

    Woot! One I recognise! Callisto (although plenty of folk beat me to it)

    1st time poster BTW.

    Callisto, Voyager 2, July 7, 1979

  8. Dave Finton says

    I was going to say Callisto too, but I have to agree with the folks that say this is one of the Voyagers. Not sure which one, though.

    Callisto by the Galileo probe May 2001

  10. ElroyJetson says

    Image of Callisto taken by Galileo probe.

  11. William928 says

    I’m guessing the moon, no idea on the spacecraft.

  13. prospero says

    I thinks its Io.

  14. ESA Exile says

    Either Callisto: Voyager 2 or an accident in a marble factory. ;- )

  15. PolishBear says

    Just like everyone else says: Callisto. Easy one.

  16. Dreamzfo says

    IO by voyeger1

  17. Spoodle58 says

    Callisto, moon of Jupiter taken by Pioneer 10 in late 1973.

  18. blancolioni says

    Coruscant, late Republic.

  19. neoguru says

    Callisto but reel strange colors. Mighta been Io in the infrared.

  20. anu says

    Image by Voyager 2 of Callisto

  21. RUF says

    Love the Courisant answer! LOL

  22. Jesper says

    Jupiter’s moon Callisto. This is an old photograph, probably by one of the Voyager spacecraft.
