A massive star exploded as a supernova around 11,300 years ago. Its remnants are one of the most studied supernova remnants ...

A companion star may have stripped silicon layers. This provided a new window into stellar death. Astronomers have observed the inner layers of a dying star through a rare type of stellar explosion ...

"The speed at which this doomed stellar system is lurching wildly, likely due to the extreme brightness, is a frantic sign of ...

The supernova explosion, designated as SN 2018gv, is found in the spiral galaxy NGC 2525. According to NASA, Hubble began observing the supernova after an amateur astronomer named Koichi Itagaki first ...

A supernova blast 2.2 billion light-years from Earth has given astronomers a deeper view into a star's centre than ever ...

Astronomers have seen a lot of stars explode, but one unusual stellar death is forcing them to rethink what they thought they knew. In 2021, a star about 2.

A distant supernova exposed elements from a star’s core. The result reshapes ideas of how massive stars evolve. According to ...

Astronomers have witnessed a rare “extremely stripped supernova” that exposed the inner silicon layers of a dying star, confirming theories of stellar fusion and offering new insight into how ...

When the two stars eventually smash into each other, the supernova explosion would be visible from Earth, even during daytime ...

New X-ray data from NASA’s Chandra telescope reveals Cassiopeia A’s chaotic final hours, showing how dying stars collapse and ...

SN2021yfj is a new kind of supernova, challenging our understanding of stellar evolution. Its progenitor lost its outer shells well before the supernova happened and only consisted of its ...

Global cooling associated with the impact of supernova remnants may have affected plants and animals, including species related to humans.
