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 ...

Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster ...

Massive stars have always puzzled scientists—how do they grow so quickly despite fierce radiation pushing material away? New high-resolution ALMA observations suggest that instead of relying solely on ...

Astronomers using NASA’s Chandra X-ray Observatory have captured an unprecedented image of a stellar bubble surrounding a young star,HD 61005, providing crucial insights into how our Sun’s astrosphere ...
