Where In The Universe Challenge #139

It’s time once again for another Where In The Universe Challenge. Name where in the Universe this image was taken and give yourself extra points if you can name the telescope or spacecraft responsible for the image. Post your guesses in the comments section, and check back on 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 an image from the Cassini spacecraft of vertical structures in Saturn’s main rings. These unexpected structures rise abruptly from the edge of Saturn’s B ring to cast long shadows on the ring. This image was taken in 2009.

Part of the Cassini Division, between the B and the A rings, appears at the top of the image, showing ringlets in the inner division. Cassini’s narrow angle camera captured a 1,200-kilometer-long (750-mile-long) section arcing along the outer edge of the B ring, and it is estimated the vertical structures tower as high as 2.5 kilometers (1.6 miles) above the plane of the rings — a significant deviation from the vertical thickness of the main A, B and C rings, which is generally only about 10 meters (about 30 feet).

See more about the image on the Cassini website.

  1. Seismic oscillations in the outer edge of Saturn’s B ring, by the inimitable Cassini spacecraft!

  2. Saturn’s rings during the equinox. I remember staring at this for almost an hour trying to make sense of it.

  3. Well, no sh…..mith-Cassegrain, what else could that be… 😉

    I’ll go for old vinyl record after some kind of a nice party anyway.

  4. Vertical structures, edge of Saturn’s B ring by NASA’s Cassini spacecraft, August 2009.

  5. The rotator on my disk brakes when i finally decide to get them fixed. photographed by a happy mechanic.

  6. Vertical structures rising from the edge of Saturn’s B-ring. Taken two weeks before the August 2009 Saturnian equinox by Cassini.

  7. Well, well, well, you *finally* managed to get a picture of my driveway, all covered with snow and ice, and the side where it all got plowed to! What? Oh wait… ok it’s Saturn’s rings snapped by Cassini… *dejected again*
