Record-breaking radio waves discovered from ultra-cool star

Penn State University astronomers have discovered record-breaking radio waves from an ultra-cool star that is not much warmer than the planet Jupiter. The team used a giant 1,000-feet radio telescope at Arecibo, Puerto Rica to look for radio signals from a class of objects known as brown dwarfs.  Brown dwarf's bridge the gap between gas giant planets, and hydrogen-fusing stars. The astronomers found that a brown dwarf named J1047+21 that lies 33.6 light years away in the constellation Leo could help boost the odds of discovering life in other places in the universe. "This object is the coolest brown dwarf ever detected emitting radio waves -- it's half the temperature of the previous record holder, making it only about five times hotter than Jupiter," Matthew Route, a graduate student at Penn State and the lead author of the discovery paper, said in a press release. The newly discovered star has a surface temperature that is not much higher than that of a giant plant, and is scarcely visible in optical light.
