Alpha Centauri B An Earth-mass planet has been spotted orbiting Alpha Centauri B, the closest star system to our own.
Remember last week when PopSci told you about a "people's choice" contest to name the planet orbiting the Alpha Centauri star system? And the International Astronomical Union had cried foul, saying the paid contest had no bearing on the names? Well, it's not really that simple. You can call a star or a planet whatever you want, and even pay to nominate your favorite; it just might not matter to anyone else.

Maybe it's because Jurassic Park is in theaters again, but we at Universe Today sometimes worry about how one person can mess up an otherwise technologically amazing system. It took just one nefarious employee to shut down the dinosaur park's security fences in the movie and cause havoc. How do we ensure science can fight against that, especially when everyday citizens are getting more and more involved in the scientific process?
Small And Large The M100 galaxy, which is about 60 percent larger than the Milky Way, next to the M97 galaxy.
From "Galaxy Size Comparison Chart" by Rhys Taylor
Think the Milky Way is big? It's puny compared to M87, an elliptical galaxy 980,000 light years in diameter. The Milky Way is only 100,000 light years in diameter. Let's not even get into Hercules A, which is 1.5 million light years across.

As updates roll in from Russia and the meteorite-related injury toll rises, you may be scrambling to remember what a meteorite really is. If you're a little rusty on your astronomy, here's some basic info about space rocks and why this one was unusual.
Red Dwarf Newest Ally In The Search For Habitable Planets like Earth.
David A. Aguilar (CfA)
In the search for stars that can support Earth-like planets, red dwarfs in our galactic neighborhood may lead the way to discovery. Recent research reveals red dwarf stars might host more habitable planets in close orbits than previously thought - just as long as its exoplanets huddle in close enough for light (but not so close that molten lava blankets the surface).
