“Ali always said I would be nothing without him. But what would he have been without me?” -Joe Frazier

We don’t normally think of deep-sky objects — seemingly fixed structures in the sky — as fighting for their lives, but when you’re a spiral galaxy caught in a gravitational storm, that’s exactly what you’re up against!

With some 2,000 other galaxies, densely clustered towards the center, what are you to do if you’re a very large spiral headed through that region at breakneck speeds? In this case, it’s moving through there are some 0.5% the speed of light!

    Perhaps the next series could be along the lines of NGCs Naughty Nights. This is a good series, so why not continue the education?
