All right, hello, welcome along. My name's Dan and it's time for a quick flick around the universe in the Fun Kids Science Weekly.

This is the only place where you can get all the most amazing, weird, epic and dangerous things that's happening in science delivered straight to your ears.

Now, this week we'll find out what happens when galaxies get so close to each other that one has to eat the other.
