Tiny supernova mistake might erase the dark energy crisis, study says
A small, seemingly technical assumption baked into the way astronomers standardize Type Ia supernovae may be responsible for the growing tension between different measurements of dark energy. New data ...
Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...
Supernova 1987A appeared in the far-southern constellation of Doradus (the Swordfish), in which the Large Magellanic Cloud is ...
An artist’s illustration depicts silicon, argon and sulfur releasing from a massive star. - Adam Makarenko/W. M. Keck Observatory Astronomers have observed what they are calling a new type of ...
On April 10, 2024, the Asteroid Terrestrial-impact Last Alert System (ATLAS) detected first light from an explosion of a massive star with roughly 12 to 15 times the sun’s mass. Just 26 hours later, ...
The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s ...
A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...
The James Webb Space Telescope has captured some bizarre imagery of an exploding star that, for some reason, kept repeating itself. In a press release, NASA said that new Webb images of what ...
A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...
A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...
