Here’s this week’s “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. The new way we’re doing this challenge is that 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 — if you dare! Check back tomorrow on this same post to see how you did. Good luck!
UPDATE (11/3): The answer has now been posted below. If you haven’t made your guess yet, no peeking before you do!!
Nice job on this one, everyone. Yes, its the sun. This image was taken back in July of 2002 of an active region of the sun. The image was produced by the Swedish 1-meter Solar Telescope on the island of La Palma, Spain. (I apologize, obviously that’s not a “spacecraft” and I should not have used the word “spacecraft” in the above paragraph — habits are hard to break.) These aren’t just little bumps on the sun. The structures in the dark sunspots in the upper central area of the image show distinct elevation above the dark “floor” of the sunspot. The height of the structures has been estimated by astronomers to be between 200 and 450 km, and the smallest resolvable features in the image are about 70 km in size! Wow!
