I found this article while at work and it was just so fascinating and the articles that lead off from it are just as cool.
I am not really a Scientist type person, so I had to read the article a few times to understand, but even re-reading the article was fascinating. They believe there may be even MORE galaxies than originally thought (approx. 2 TRILLION galaxies).
The one that lead on from this one was We’re on a collision course with the Andromeda Galaxy — here’s what will happen to Earth
If you don’t want to read this, I’ll give you a short rundown. The Milky Way will be colliding with the Andromeda Galaxy, in about 3.75 billions years though. Not much will happen to Earth (if we haven’t already destroyed our own planet by then). However, the night sky will apparently be “something we have never seen before”. Please watch the slideshow, it is so awesome!
