Whilst spelunking the intertoobz today, I stumbled across this phenomenal video showing what happens when galaxies collide:
Ethan Siegel at Starts With a Bang also has some dramatic photos illustrating why we're a spiral galaxy. Those who like to claim there's no beauty in science need to visit that post forthwith.
George referred me to another post of his that tells you what you need to know about getting involved in astronomy. You'll likely need it after viewing the above. Then you'll want to have a look at A Mysterious Light on the Darkest Night. Gracias, George!
Happy Science Saturday, my darlings!
