Boffins go back to the drawing board Researchers have located the most massive stellar black hole ever discovered, just three million light-years away in a nearby galaxy. The stellar remnant is in a binary system known as M33, orbiting a huge companion star. The researchers say the find is "intriguing", because of what it suggests about stellar evolution.â¦

A new NASA space telescope will give scientists a peek at some of the most energetic objects and events in the universe. The new Gamma-ray Large Area Space Telescope to be launched next spring doesn't see visible light like our eyes, but gamma rays, the most energetic photons in the electromagnetic spectrum.
