The recent detection of a gamma-ray burst from a massive blue supergiant is helping astronomers understand how the universe's primordial stars ended their lives in cataclysmic explosions. But more than this, it revealed several features never seen before in a stellar explosion.
Earlier this year, astronomers detected one of the brightest explosions ever seen in space. Now, some seven months later, the unusual event has been confirmed as a gamma-ray burst — and it's changing the way we think about these cataclysmic explosions.
Astronomers have found a mind-bogglingly large structure in a remote part of the Universe — an expanse of space that's so big it takes light 10 billion years to traverse.
On April 27, NASA’s Fermi and Swift satellites detected a record-setting burst from a dying star located in a nearby galaxy. Most likely the result of a massive supernova, it produced the highest-energy light ever detected by scientists.
Scientists working at the University of Warwick have identified an undocumented type of gamma-ray burst, the product of massive stars destroyed in a way previously unknown to astronomers.
