Betelgeuse, one of the brightest stars in the constellation Orion, has long fascinated astronomers because it is nearing the end of its life. Observations from the Hubble Space Telescope revealed a ...

An international research team led by Chinese scientists has discovered new evidence about Type II-P supernovae, suggesting that some of these stellar explosions may originate from merged binary stars ...

Asrtronomers managed to pinpoint which star in the NGC 1637 galaxy turned into a supernova 40 million years ago, they used the Webb telescope.

Any star with a name like Betelgeuse must be remarkable. The unusual name is Arabic for “armpit.” It marks the shoulder ...

New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to Type II supernova explosions.

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

The star’s surface temperatures had increased by more than 1,000 degrees Celsius (1,800 Fahrenheit), turning its signature red color to yellow. It also shrank as a result of becoming hotter, going ...

Astronomers used Webb to find the star behind supernova 2025pht, revealing how thick dust can hide massive red supergiants.

The largest stars in the universe live the life of a rock star - they are born brilliant, live fast and die young. If that is the case, the one named WOH G64 might be considered the stellar equivalent ...

Astronomers report the rapid transition of WOH G64 from a red supergiant to a yellow hypergiant, based on photometric and spectroscopic observations published in Nature Astronomy.

One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't sure when it will go supernova.

NASA’s James Webb Space Telescope has uncovered evidence of a stellar explosion that could help solve a cosmic mystery millions of years in the making: what NASA calls the “case of missing red ...
