Where In The Universe #43

It’s Wednesday, so that means its time for another “Where In The Universe” challenge to test your visual knowledge of the cosmos. See if you can name where in the Universe this image is from, and give yourself extra points if you can name the spacecraft responsible for the image. Make your guess and post a comment. Check back sometime on Thursday to find the answer and see how you did (and yes, I’ll try to remember to post the answer in a timely fashion this week!)

UPDATE: The answer has now been posted below.

Pretty much everyone said this was Europa, and guess what, you’re right! This highly detailed image of Jupiter’s moon Europa was taken by the Galileo spacecraft. It’s a processed image to show the differences in materials that cover the ice. The red linear features are cracks and ridges that stretch for thousands of kilometres across the moon’s surface, resulting from tides raised by the pull of Jupiter. The mottled red terrain shows areas that have been disrupted and where ice blocks have moved around. The red material is thought to be a non-ice contaminant, such as salts brought up from the ocean thought to lie beneath Europa’s icy shell. Image: NASA/JPL/University of Arizona.

Great job everyone, and check back again next week for another WITU Challenge!

    Man…am I the first to say…Europa?!

  2. rui borges says

    robbi…I’l bite your legs of! 😉

  3. robbi says

    rui borges -lol sorry about that lol

  4. ringman says

    it’s Europa

  5. Jorge says

    This one is easy: Jupiter’s moon Europa. The spacecraft is Galileo, although I’m less certain about this part.

  6. Sofista says

    Surface of Jupiter’s moon Europa, the spacecraft is Galileo (1996).

  7. Raselhague says

    Yep, looks like Europa to me. 🙂

    Less sure on the Galileo but I think so.

  8. Don Alexander says

    Definitely Europa, in false or at least exaggerated color.

    And very probably Galileo, I don’t think the Voyagers caught so much detail.

  9. Reynard says


  10. Chantel says

    Photo is Europa taken by Galileo in the 90s.

  11. RetardedFishFrog says

    Too easy – that’s Europa. Woo Hoo! I got one!

  12. Haplo says


  13. Jennifer says


  14. Farcall says

    Hapio: Don’t worry, at the rate we’re going we’ll never attempt a landing there… On Europa as taken by the Galileo spacecraft.

  15. Astrofiend says

    Gotta go with false colour of Europa there – colour coded to bring out differences in chemical composition of the icy surface.

  16. Eduardo says

    Europa… how I whish were here… (perhaps in digital form)

  17. MetalDave says

    Europa Rocks!

  18. Wolter says

    Yep Europe and Yep Galilieo

  19. Terragen says

    Finally one I know immediately – Europa.

  20. Damir says

    Surface of Europa, taken by Galileo.

  21. Europa. But much more importantly, it shows the coloured lines that seem to point to the potential for a lichen type of growth that might, might, be life on another body in the solar system.

  22. chandramohan.P.R says

    Cracks on the surface of Europa moon of jupiter Black iquid hydrocarbons coming out in the cracks.

  23. Taunide says

    Europa Voyager 2

  24. Frank says

    Europa. All too easy. Although I can’t give myself the extra points, this should be changed to ‘Where in our Solar System’.

  25. The Dude says

    How many extra points do we get? This is the easiest one thus far. The extra point value must be low.

  26. Will says

    Europa, from Galileo

  27. Timmy says

    Any space geek who does not immediately recognize this as Europa should have their pocket protectors revoked immediately.

    And hooray that the major space powers are finally going to get serious about exploring the one other world in this solar system that may have actual living life on it! Even if it will take another 2 decades to happen.

  28. Joe M. says

    Europa, Jupiter’s moon. Don’t care which spacecraft took this picture

  29. Diana says

    I think I might actually be right this time! Europa- Galileo
    ~Final answer~

  30. Dave Hall says

    I think it is closer to home. Looks like blood vessels in an eye

  31. Dori says

    Yup, I like Dave Hall’s answer! As a former bio teacher, that’s the first thing I thought of too– retinal patterns. As for the spaceship, I suggest it was actually a submarine, the Proteus, from the movie “Fantastic Voyage”!

  32. Per Hultqvist says

    I’m with Dave on this one, it’s an eye…Got to go against the stream sometimes…

  33. Al says

    “All these worlds are yours except Europa, attempt no landings there”

  34. Wim Ghoris says

    Jupiters moon Europa, one of the more exotic pictures…

  35. alfamonaro says

    Europa is really easy to pick, btw is it a false colour image, I’m puzzled as to why some features the lines appear red?

  36. MartyR says

    It’s a close-up of my eyeball on a Sunday morning! ;0)

  37. D.R.R. says

    Europa (faux-color imagery)
