The supernova was the death of a red supergiant star 500 times larger than the sun, in a galaxy just 22 million light-years ...

The explosive death of a star - a supernova - is among the most violent cosmic events, but precisely how this cataclysm looks ...

Astronomers have captured a first-of-its-kind image of a massive dying star.

Swift observations with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed the explosive ...

Some of the earliest images ever taken in the wake of massive star’s death give astronomers important clues about what triggers a supernova.

When this shock reaches the surface, it releases an enormous burst of energy. The star brightens dramatically, becoming visible as a supernova. For a short period, astronomers can study the initial ...

V Sagittae’s violent mass transfer hints at an imminent nova—and a future supernova visible from Earth. Binary star systems are fairly common in the universe, as are pairs where one star is a compact ...

When a star explodes, it expands at high speed. What a supernova looks like immediately after its onset was therefore unknown ...

Is there anything more dramatic than an exploding star? More than just extraordinarily bright, energetic events that can ...

This revelation means scientists might have to rethink Type II supernova models, which would result in some of these cosmic ...

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 ...
