It took about 50 exploding stars to upend cosmology. Researchers mapped and measured light from Type Ia supernovae, the ...

The two objects make for a strange pair. Unlike Betelgeuse, which is approaching the end of its life, the blue-white companion (or Betelbuddy) has yet to start burning hydrogen in its core. In other ...

Will the universe keep expanding forever, or slow down and collapse? A University of Hawaiʻi at Mānoa researcher contributed ...

The fact that Betelgeuse is one of the brightest stars in the sky over Earth, visible with the naked eye, has made it one of ...

For the first time, astronomers have spotted a star that exploded not once, but twice. A new image of a roughly 300-year-old supernova provides visual evidence that some dying stars undergo a double ...

Pictures of a distant supernova remnant show two concentric rings, providing clear evidence that exploding white dwarf stars ...

MUSE allows astronomers to map the distribution of different chemical elements, displayed here in different colours. Calcium is shown in blue, and it is arranged in two concentric shells. These two ...

Stars often die with a final burst of beauty. For the first time, astronomers have captured visual proof that a star can ...

Now astronomers have discovered that this red supergiant, known to many as the hunter’s shoulder in the Orion constellation, ...

"This discovery heralds a broader understanding of the diversity in massive stars' deaths and a need for deeper ...

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...
