Physicists may soon witness a cosmic fireworks show: the explosive death of a primordial black hole. Once thought to be unimaginably rare, new research suggests there’s up to a 90% chance of catching ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

A rare star reveals how the Universe's first stars exploded, helping explain the Milky Way’s outer halo and its unusual chemistry.

Imagine looking up at the night sky and seeing a star suddenly burst into a blaze of light brighter than anything nearby. A flash so bright that it briefly outshines an entire galaxy before fading ...

Astronomers using the James Webb Space Telescope (JWST) may have discovered the most distant supernova in the universe. This stellar explosion, hosted by a very faint galaxy, occurred when the ...

Physicists have not yet watched a black hole literally blow itself apart, but they are closing in on the conditions where such an event might finally be seen. At the same time, telescopes are catching ...

Physicists think we could see such an explosion in the next 10 years - and it would 'revolutionize physics and rewrite the history of the universe'. This artist’s concept takes a fanciful approach to ...

For decades, scientists have tried to measure how fast the universe is expanding. This expansion rate is known as the Hubble constant, and it plays a central role in understanding the history and ...

Primordial black holes are hypothetical black holes thought to have formed moments after the Big Bang. Because they supposedly formed about 14 billion years ago, and black holes are thought to ...

An artist's impression of a magnetar with a wobbly accretion disk. (Joseph Farah and Curtis McCully) A never-before-seen 'chirp' in the light of an exploding star has revealed new clues about the ...
