Are you ready for another Where In The Universe Challenge? Take a look 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. As usual, we’ll provide the image today, but won’t reveal the answer until tomorrow. 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. Don’t peek before you make your guess.
What you are seeing here is the dark side of Saturn’s moon Titan, with sunlight filtering through the moon’s hazy atmosphere. And obviously, the Cassini spacecraft is responsible for this image.
An airless satellite would appear in this viewing geometry only as a lit crescent. But Titan’s thick atmosphere scatters light around all edges of the planet to create a ring of light.
This view looks toward the Saturn-facing side of Titan. North on Titan is up and rotated 45 degrees to the left. The images were acquired at a distance of approximately 1.8 million kilometers (1.1 million miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 157 degrees. Image scale is 11 kilometers (7 miles) per pixel.
Nice job, everyone! Check back next week for another WITU challenge!
