Astronomers from Nanjing University in China have detected gamma ray emission from two star-forming galaxies designated M33 and Arp 299. The finding, which is detailed in a paper published March 17 on arXiv.org, could be ...
Every so often, astronomers glimpse an intense flash of radio waves from space—a flash that lasts only instants but puts out as much energy in a millisecond as the sun does in a few years. The origin of these "fast radio ...

A team of researchers from the U.S., New Zealand, Australia and Germany has found evidence suggesting that a type of star formation near the center of the Milky Way is responsible for large gamma ray emissions, not dark matter. ...
(Phys.org) —More than 12 billion years ago a star exploded, ripping itself apart and blasting its remains outward in twin jets at nearly the speed of light. At its death it glowed so brightly that it outshone its entire ...
