Felicia Day Explains Colliding Galaxies

You may recognize Felicia Day as Dr. Horrible's red-haired obsession (or maybe from that appliance commercial). And if you've been reading this blog, you probably have heard of NASA's Spitzer Space Telescope, which was responsible for last month's discovery of a massive ring around Saturn. Add the two together and you get the latest video about colliding galaxies from IRrelevant astronomy. If you find this one funny, and if you are geeky enough to recognize names like Sean Astin and George Takei, you'll probably spend the rest of the day giggling as you watch earlier episodes from the series. They can be found intermingled with more traditional educational videos on the telescope's YouTube site. Enjoy!
