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

For the first time, scientists determined the shape of a supernova's shock front as it burst through the surface of a dying ...

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

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 ...

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

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

On April 10, 2024, astronomers began the fast-paced mission to capture supernova SN 2024ggi. Study coauthor Yi Yang of Tsinghua University in China initially learned about its sighting shortly after ...

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

Astronomers have, for the first time, captured the moment a massive star exploded, observing the blast just as it burst ...

Chris Ashall, an assistant astronomer at the UH Mānoa Institute for Astronomy, was part of the global team that zeroed in on the stellar explosion known as SN 2024ggi. The supernova was first spotted ...

This artist’s impression shows a star going supernova. About 22 million light-years away the supernova, SN 2024ggi, exploded ...

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