Fermi spots a supernova"s "fizzled" gamma-ray burst
On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record.....»»
Challenging the big bang puzzle of heavy elements
It has long been theorized that hydrogen, helium, and lithium were the only chemical elements in existence during the Big Bang when the universe formed, and that supernova explosions, stars exploding at the end of their lifetime, are responsible for.....»»
Nature of unknown gamma-ray sources revealed

New Studies Argue Distant Cosmic Gamma-Ray Explosion Was Actually Just Russian Space Junk
"Last year, a team of astronomers made a blockbuster claim, saying they had captured the most distant cosmic explosion ever — a gamma ray burst in a galaxy called GN-z11," reports Science magazine. "But that flash of light — supposedly.....»»
Astronaut Spots Rare and Ethereal "Transient Luminous Event" From ISS
"Transient luminous event" sounds like a euphemism for a ghost, but it's actually a beautiful phenomenon that can sometimes be seen from the International Space Station. European Space Agency astronaut and current ISS resident Thomas Pesquet shared a.....»»
Astrophysicists explain the origin of unusually heavy neutron star binaries
A new study showing how the explosion of a stripped massive star in a supernova can lead to the formation of a heavy neutron star or a light black hole resolves one of the most challenging puzzles to emerge from the detection of neutron star mergers.....»»
Process leading to supernova explosions and cosmic radio bursts unearthed at PPPL
A promising method for producing and observing on Earth a process important to black holes, supernova explosions and other extreme cosmic events has been proposed by scientists at Princeton University's Department of Astrophysical Sciences, SLAC Nati.....»»
Energy burst from most distant known galaxy might have been a satellite orbiting Earth
The cosmos is the stage for a variety of giant explosions. These include stellar flares, where stars suddenly release magnetic energy; and neutron star mergers, where two dense stars collide together. But one class of explosions outshines the rest: g.....»»
