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

Astronomers have recently made a groundbreaking discovery, capturing the earliest observations of a supernova’s initial ...

The Eastern Veil Nebula is part of a colossal supernova remnant known as the Cygnus Loop. Dutch astrophotographer Cornelis ...

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 ...

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 ...

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

Astronomers have, for the first time, recorded the moment a star’s explosion broke through its surface. The nearby supernova, ...

A University of Hawaiʻi Mānoa astronomer helped pull off a cosmic first: mapping the three‑dimensional shape of a star’s ...

Observations with NASA’s Chandra X-ray Observatory have provided the first X-ray evidence of a supernova shock wave breaking through a cocoon of gas surrounding the star that exploded. This discovery ...

Two major astronomy research programs, called EMU and PEGASUS, have joined forces to resolve one of the mysteries of our Milky Way: where are all the supernova remnants? A supernova remnant is an ...
