NASA's retired Compton mission reveals superheavy neutron stars
Updated : 3 years, 2 months ago IST
Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into a black hole. This fleeting, massive object likely formed from the

Scientist explains mystery of gamma-ray emitting bubbles around Milky Way'
Updated : 3 years, 2 months ago IST
Large gamma-ray emitting bubbles around the center of our Galaxy were produced by fast-blowing outward winds and the associated "reverse shock," suggests a scientist from Tokyo Metropolitan University.

Researchers reveal that meteorites could have given Earth building blocks
Updated : 3 years, 3 months ago IST
Even as detailed images of distant galaxies from the James Webb Space Telescope show us more of the greater universe, scientists still disagree about how life began here on Earth. One hypothesis is that meteorites delivered amino acids life's building blocks to our planet. Now, researchers h

NASA missions probe game-changing cosmic explosion
Updated : 3 years, 3 months ago IST
On Dec. 11, 2021, NASA's Neil Gehrels Swift Observatory and Fermi Gamma-ray Space Telescope detected a blast of high-energy light from the outskirts of a galaxy around 1 billion light-years away. The event has rattled scientists' understanding of gamma-ray bursts (GRBs), the most powerful ev

Research: Short gamma-ray bursts traced farther into distant universe
Updated : 3 years, 3 months ago IST
Astronomers have developed the most extensive inventory to date of the galaxies where short gamma-ray bursts (SGRBs) originate. Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers pinpointed the galactic homes of 84 SGRBs and probed the characteristi
