Just 548 light years from Earth, this massive red supergiant nearly 1,000 times larger than our Sun is about to explodeAstronomers have discovered Betelgeuse harbors a hidden stellar companion. This finding complicates predictions about its eventual supernov...- In 1967, US satellites searching for nuclear tests detected mysterious flashes from space. Decades later, scientists uncovered secrets of gamma-ray bursts, which can release more energy in 10 seconds than Sun will emit over its entire 10-billion-year lifetimeGamma-ray bursts, first detected accidentally in 1967, have long puzzled astronomers. Recent observations of their afterglows are now chall...
