Some stars may transform into black holes without exploding into supernovae. Now, astronomers have finally spotted it as it ...

To resolve the black hole, they used the Event Horizon Telescope, a global radio telescope array with an effective aperture ...

NASA's IXPE (Imaging X-ray Polarimetry Explorer) has helped astronomers better understand the shapes of structures essential ...

"There are trillions of stars in the universe, and about every second, one of them explodes." ...

Black holes are points in space that are so dense ... In the stellar remnants of a supernova, however, there are no longer forces to oppose that gravity, so the star core begins to collapse ...

Discover the explosive end of a star's life—supernovas. Learn what causes these cosmic events and their impact with ...

Researchers have documented a rare supernova, 2023ufx, the most metal-poor stellar explosion observed, located in a dwarf ...

The result is a supernova explosion, a calamitous event that destroys the star and leaves behind a black hole or a neutron star. However, it appears that sometimes these stars fail to explode as ...

India’s X-ray Polarimeter Satellite (XPoSat) has been launched to study black holes and other high-energy cosmic phenomena.

In recent years, astronomers have spotted tantalizing clues that some massive stars turn into black holes before they can ...

For stars that are eight times or more the mass of our sun, the outer layers rebound off the iron core, leading to a gigantic explosion called a supernova and leaving behind a black hole or a ...

In recent years, astronomers have spotted tantalizing clues that some massive stars turn into black holes before they can eject material outward — in an event they call a failed supernova. Yet ...
