The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

“The explosions of white dwarfs play a crucial role in astronomy,” said Priyam Das, a study co-author and PhD student at the University of New South Wales Canberra, Australia. “Yet, despite their ...

A strange cosmic blast that lit up the sky in two distinct acts is forcing astronomers to rethink how stars live and die. The event, tagged AT2025ulz, appears to be the first known case where a ...

The European Southern Observatory (ESO) published a photograph revealing the remnants of a white dwarf star that ended its existence in a double explosion. This marks the first discovery of a stellar ...

Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” supernova, where an initial helium blast on the star’s surface triggers a ...

A double explosion, in which a dying star split, then recombined, may be a long-hypothesized but never-before-seen "superkilonova." When you purchase through links on our site, we may earn an ...

The ESO's Very Large Telescope points at the exact position of the supernova remnant SNR 0509-67.5, or "the expanding shells of a star that detonated twice," located in the Large Magellanic Cloud, a ...
