Mystery Star Explained by New Type of Massive Cosmic Explosion – 10x More Energetic Than a Supernova
‘Magneto-rotational hypernova’ soon after the Big Bang fuelled high levels of uranium, zinc in ancient stellar oddity. A massive explosion from a previously unknown source…
An international team of astronomers has observed the first example of a new type of supernova. The discovery, confirming a prediction made four decades ago,…
Astronomers have captured the movement of the expanding remains of an exploded star. Chandra data taken over 14 years show a blast wave and debris…
Pictured is the supernova of the type Ia star 1994D, in galaxy NGC 4526. The supernova is the bright spot in the lower left corner…
Shells of material surround the stars of Eta Carinae. A Gamma-ray burst coming from those stars should release large amounts of light as it collides…

Artist’s impression of a yellow supergiant in a close binary with a blue, main sequence companion star, similar to the properties derived for the 2019yvr…
Cosmologists have found a way to double the accuracy of measuring distances to supernova explosions – one of their tried-and-true tools for studying the mysterious…
Astronomers using NASA’s Chandra X-ray Observatory have announced the discovery of an important type of titanium blasting out from the center of the supernova remnant…
Data from Chandra and NuSTAR provide evidence for the existence of a structure known as a “pulsar wind nebula” at the center of the Supernova…
