Researchers stitched together hundreds of images from the Very Large Telescope to form a breathtaking photo of a nearby ...

Low-mass stars like our Sun expel their outer layers as a planetary nebula because of what is going on in the star’s core as it ages.

Supernovae like these are very luminous and referred to as "standard candles" in astronomy. As fixed points, they are used to ...

While astronomers expect many supernova remnants remain to be discovered, the fact that Teleios was spotted at all “is pure luck,” Filipović says. Had it been located closer to the galactic plane, ...

Some stars have a much different end of life than previously thought. Astronomers have observed for the first time traces of a star that exploded twice. This discovery challenges current ...
