Seven Earth-sized Exoplanets!

Scientists have found seven Earth-sized planets in the TRAPPIST-1 star system, forty light years away. There's a lot of coverage on it, from CNN, Fox News,  ABC News, and every other news outlet under the sun (this sun, not TRAPPIST-1).  They're orbiting a dwarf star but close enough there may be liquid water.  Very, very cool stuff.
