“The first two Earth-sized exoplanets found by Kepler are shown here in comparison to Earth and Venus. Kepler-20e has a diameter of 6,900 miles, meaning it is 0.87 times the size of Earth and 0.92 times the size of Venus. Kepler-20f has a diameter of 8,200 miles, meaning it is only 3 percent larger than Earth. They are part of a five-planet system orbiting the star Kepler-20. All five would fit within the orbit of Mercury in our solar system.” —From Harvard

NGC 4755: A Jewel Box of Stars
The great variety of star colors in this open cluster underlies its name: The Jewel Box. One of the bright central stars is a red supergiant, in contrast to the many blue stars that surround it. The cluster, also known as Kappa Crucis contains just over 100 stars, and is about 10 million years old.

I usually would never post a CNN video, because of the ugliness of the format and the ads and what not, but this is such a cool video. 132 Shuttle Launches in 132 Seconds. (Now, 133, because the flight yesterday) Very, very cool. Shows all of them, from flight one. Also, very sad, because Challenger’s doomed launch and Columbia’s final flight are shown. They’re the ones in black and white.
Seriously, watch this.
