Scientists Develop New Approach to Capture Gravitational Wave Memory from Supernovae
A study published in Physical Review Letters highlights new methods to detect the gravitational wave memory effect, a unique phenomenon predicted by Einstein's general relativity. Core-collapse supernovae (massive stellar explosions) generate these low-frequency gravitational waves, offering a rare glimpse into stellar interiors. Despite their weak...

Arecibo Observatory Data Helps SETI Uncover Secrets of Pulsar Signals and Cosmic Distortions
Data from the now-collapsed Arecibo Observatory continues to drive major discoveries in space science. Sofia Sheikh and her team from the SETI Institute utilised archived data to investigate the signals of pulsars—dense neutron stars emitting radiation like cosmic lighthouses. Their study focused on how these signals are distorted by interstellar...

Record-Shattering 'Failed Star' Uncovered By James Webb Space Telescope
James Webb Space Telescope has identified the new record-holder: a tiny, free-floating brown dwarf with only three to four times the mass of Jupiter.

"Very Exciting": In A First, Newborn Star's Spinning Disk Seen In Another Galaxy
Our sun and other stars form when a dense clump of interstellar gas and dust collapses under its own gravitational pull.

Scientists Detect Gravitational Waves From A New Kind Of Nova, Sparking A New Era In Astronomy
Some 130 million years ago, in a galaxy far away, the smoldering cores of two collapsed stars smashed into each other. The resulting explosion sent a burst of gamma rays streaming through space and rippled the very fabric of the universe.
