This analysis confirms the existence of a jet emerging from the nucleus of the star, producing the GRB, and adds a new component to the picture During the early phases, the jet interacts with the ...

The peculiar elemental makeup of one star in the Milky Way could be due to a massive type of stellar collapse in the early universe, a team of astronomers announced today. The finding could help ...

Unlike our Sun, which is a relatively low mass star and which will gradually fade before expanding into a red giant at the end of its life, larger mass stars undergo extreme explosive events when they ...

An international team of astronomers has discovered the first evidence of the destruction of a collapsed and rapidly spinning star in a phenomenon they have called a magneto-rotational hypernova. This ...

The star SMSS J200322.54-114203.3 (centre, with crosshairs) in the south-eastern corner of the constellation Aquila is thought to have formed from the remnants of a short-lived, even more ancient star ...

A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous ...

Thirteen billion years ago, in the depths of the Milky Way, an ancient star began to collapse. It spun, faster and faster, generating enormously powerful magnetic currents, before detonating in an ...

The end of a star's life can occur in a tranquil manner in the case of low mass stars, such as the Sun. This is not the case, however, for very massive stars, which suffer such extreme explosive ...

Extremely bright supernovas, called hypernovae, have been linked to gamma-ray bursts, but theorists have struggled to explain how a collapsing massive star could produce a magnetic field a million ...
