I'm still early in the whole "figuring everything out" process, but I THINK I found a crater chain. Can someone verify this? If you go from the center of the image to the left, about an inch and a half from the left edge you'll run into the middle of a chain of five going diagonally upward toward the corner. The more I look at this image the more I see other possible chains, but that's the one that has me convinced. So... is it?
Hello DJ_59, I think I see what you mean. Five craters in a very straight line...
Crater chains can look like this, when the craters are spaced enough apart that their ejecta doesn't interfere. But here, you will notice that the craters closer to the bottom appear more degraded than the upper craters (their edges aren't as sharp, their depth more subdued). In the absence of other evidence, this suggests that these craters were created at different times, and so aren't a chain. Our eye-brain system is very good at finding patters (which is why the Zooniverse was created
), but in this case, I think it's a false positive.
That said, thanks for posting this. It's a great image for this discussion.
