Andromeda

It’s a baby picture of our universe, when it wasn't very old. It’s a picture of the cosmic microwave background, of the hot spots where galaxy clusters will form. Someone else could probably elaborate on it more than that.

Hello, I've been a member of this forum for a while. I've just been lurking and reading mostly. Never really had anything to post before, as there are many very intelligent people in here. I'm also a member of other astronomy/science forums and I thought I would post this in here as it has gotten lots of post in the other forums. I'm starting to think that it's not fair to only be allowed one question though? Even though getting some of the most fundamental questions answered would lead to other questions being answered. It would also lead to more unanswered questions. If you could have one question answered about the mysteries of the Universe what would it be?
