The new paper argues that, in SN 1181, the first phase of the supernova fizzled out and left behind an unusually active ...

An international team of astronomers, working with researchers from University College Dublin and other institutions, has ...

In 2017, astronomers found hypervelocity stars believed to have come from the Large Magellanic Cloud, supposedly kicked out of binary systems by supernovae. What kept the surviving star from being ...

Many stars die spectacularly when they explode as supernovae. During these violent explosions, they leave behind thick, ...

How much light does a supernova shed on the history of universe? New research by cosmologists at the University of Chicago and Wayne State University confirms the accuracy of Type Ia supernovae in ...

While walking home on November 11, 1572, astronomer Tycho Brahe idly glanced at the sky. He was surprised to see a bright star in the constellation Cassiopeia that hadn’t been there before. The new ...

This study could transform our understanding of the future of the universe and raise the possibility that the universe may ...

Supernovae are classified primarily based on their spectral characteristics, notably the presence or absence of hydrogen lines, leading to type I (no hydrogen) and type II (hydrogen present) ...

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

Some 2 million years ago, the life of a nearby star ended—not with a whimper, but a bang. Its death—a stellar explosion called a supernova—was so cataclysmic that it sent the star’s innards hurtling ...

Stars are balls of glowing gas, with a nearly spherical shape. Accordingly, one would expect that when some stars explode as supernovae at the end of their lives, the resulting colossal fireballs ...

Some of the brightest stellar explosions in the Universe should be classified together as a new type of supernova, according to an international collaboration of researchers. The group has catalogued ...
