This artist’s illustration of Supernova 1987A shows the dusty inner regions of the exploded star’s remnants (red), in which a neutron star might be hiding.…
For just the second time ever, astrophysicists have spotted a spectacular flash of ultraviolet (UV) light accompanying a white dwarf explosion. An extremely rare type…
The material ejected by the supernova will initially expand very rapidly, but then gradually slow down, forming an intricate giant bubble of hot glowing gas.…
Crab Nebula is a supernova remnant. In the (Western) year 1054, Chinese astronomers recorded the supernova that blasted the nebula into existence. Credit: NASA, ESA,…

Supernovae bombarded Earth with cosmic energy starting as many as 8 million years ago, with a peak some 2.6 million years ago, initiating an avalanche…
Artist’s concept illustrating Supernova 1987A as the powerful blast wave passes through its outer ring and destroys most of its dust, before the dust re-forms…
This is an artist representation of the hypernova. The interaction of the jet with the outer layers of the star forms a cocoon that surrounds…
