Monster Black Hole Busts Theory 248

Genocaust writes "A stellar black hole much more massive than theory predicts is possible has astronomers puzzled. Stellar black holes form when stars with masses around 20 times that of the sun collapse under the weight of their own gravity at the ends of their lives. Most stellar black holes weigh in at around 10 solar masses when the smoke blows away, and computer models of star evolution have difficulty producing black holes more massive than this. The newly weighed black hole is 16 solar masses. It orbits a companion star in the spiral galaxy Messier 33, located 2.7 million light-years from Earth. Together they make up the system known as M33 X-7."

NASA STEREO Spacecraft Set to Launch 82

An anonymous reader writes "As first reported on last year, NASA's STEREO mission is set to launch tonight at 8:38pm EST. The two near-identical spacecraft will give us unprecedented stereoscopic views of the Sun-Earth system, hopefully leading to the creation of the first 3-D movies of the Sun! Launch can be watched live on NASA TV with coverage starting at 6:30pm EST."
