A dozen luminous blue outbursts were thought to be unusual supernovae. A new outburst, the brightest yet, suggests it's ...

In 1987, astronomers observed an incredible star explosion in a galaxy not too far away in the Large Magellanic Cloud. Now, researchers suggest that the famed supernova, called 1987A, was created by a ...

Roughly 300 years ago, light from a supernova first appeared in Earth’s skies and formed the brilliant object Cassiopeia A. That blast emitted powerful shockwaves packed with clues about how a star ...

A Type Ia supernova explodes (as shown in the dark brown color). The supernova material is ejected outwards and slams into its companion star (in light blue color). This violent collision produces an ...

Thanks to a worldwide network of 18 robotic telescopes, researchers led by the University of California Santa Barbara (UCSB) were able to catch a brief blue glow in the sky which, they say, was the ...

An international collaboration led by the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) have discovered that the color of supernovae during a specific phase could be an ...

Astronomers have discovered that the color of supernovae during a specific phase could be an indicator for detecting the most distant and oldest supernovae in the Universe -- more than 13 billion ...
