For the first time, Webb catches the before and after of a supernova

For the first time, Webb catches the before and after of a supernova

Astronomers say they’ve captured the clearest look yet of a star on the brink of supernova. An international team used NASA’s James Webb Space Telescope to backtrack and find the original star that suffered a cataclysmic explosion on June 29. The discovery is an unprecedented accomplishment for the observatory. Identifying the original star was harder to achieve than it sounds. …

JWST spots dust-cloaked ‘red supergiant’ star just before it went supernova

JWST spots dust-cloaked ‘red supergiant’ star just before it went supernova

For decades, astronomers have searched the skies for a missing population of doomed stars — the massive red supergiants that theory predicts should end their lives in powerful stellar explosions, but somehow rarely seem to. Now, thanks to the James Webb Space Telescope (JWST), the mystery may finally be clearing up, quite literally. In a new study, a team of …

“Like Nothing Anyone Has Ever Seen Before” – Bizarre Supernova Stuns Scientists

For the first time, astronomers have seen the inner layers of a star revealed in its final moments. The finding suggests a new, more violent pathway for how massive stars die. Credit: Shutterstock A distant supernova exposed elements from a star’s core. The result reshapes ideas of how massive stars evolve. According to long-standing theory, stars are built in layers …

Astronomers discover a ‘forbidden’ pulsar fleeing a supernova in a seemingly empty region of the Milky Way

Astronomers discover a ‘forbidden’ pulsar fleeing a supernova in a seemingly empty region of the Milky Way

Astronomers have discovered an extraordinary celestial system containing a runaway pulsar fleeing the scene of a massive stellar supernova explosion. What makes this system even more spectacular is the fact that it should be “forbidden” in the empty region of the Milky Way in which it was found. The system, given the name “Calvera” after the villain in the 1960 …

Scientists Think This Star Could Be the Next Supernova

Red supergiant DFK 52 and its surroundings as seen by ALMA. The vast, complex bubble blown by this extreme star is about 1.4 light-years across, thousands of times wider than our Solar System. ALMA measures light invisible to the human eye, with a wavelength of around 1.3 millimeters, emitted by molecules of carbon monoxide and silicon monoxide. Thanks to the …
