The Einstein Probe caught the faintest X-ray shock breakout ever seen from this class of supernova. Two independent teams found no jet, no burst, and a 20-solar-mass Wolf-Rayet star that should have made both.
The Jellyfish Nebula turns out to have a sibling. A Stanford-led team used 16 years of gamma-ray data to show the two remnants came from a single binary system — a pairing never seen before.
A team led by SUNY Poly and the Kavli IPMU finds that a primordial black hole passing through a white dwarf could tidally heat it into a thermonuclear runaway — and that the resulting explosions would leave a distinctive chemical signature already visible in the Milky Way.
A rising, bird-like pattern in an exploding star's light gave away the birth of one of the universe's most magnetic objects — and forced Einstein's relativity into the story of a supernova for the first time.
Watching a distant supernova flicker four times in a quickening rhythm, astronomers caught the moment an ultra-magnetic neutron star switched on — and saw Einstein's relativity at work in an exploding star.
Following a gamma-ray burst to its source, the James Webb Space Telescope caught a collapsing massive star from the cosmic dawn and, for the first time at such a distance, imaged its faint host galaxy.
Nearly two decades of NASA data revealed that a rapidly spinning magnetar powered superluminous supernova SN 2017egm, helping settle a long debate over what drives the universe's brightest stellar explosions.
Researchers using the DAMPE space telescope uncovered a hidden rule governing ultra-powerful particles that travel across the galaxy, potentially solving one of physics' longest-standing puzzles.
Breakthrough experiment measures key reaction creating selenium-74, shedding new light on supernova nucleosynthesis while revealing gaps in current theories.
Breakthrough experiment directly measured how arsenic-73 captures protons to form selenium-74, shedding new light on the mysterious origin of proton-rich elements in supernovas.
International astronomers led by Stockholm University's Oskar Klein Centre discovered SN 2025mkn, a Type II supernova 9 billion light-years away whose light is bent and amplified by an entire foreground galaxy, creating a natural telescope of unprecedented power.
Breakthrough experiment directly measures key nuclear process that creates selenium-74 in supernova explosions, cutting uncertainty in stellar models by half.
A 45-scientist team at Michigan State's FRIB measured the arsenic-73 + proton reaction that occurs inside supernovae, cutting uncertainty in p-nuclei abundance predictions by 50% and advancing a 60-year-old astrophysics mystery.
The Imaging X-ray Polarimetry Explorer spacecraft revealed new detail in the remains of a stellar explosion first recorded by Chinese astronomers in 185 AD, using polarized X-rays to map its magnetic fields.
An unprecedented superluminous supernova, split into multiple images by a foreground galaxy, may help resolve the Hubble Tension
