The cosmic pinwheel that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as once ...

The U.S. Naval Research Laboratory (NRL), in partnership with NASA's Marshall Space Flight Center (MSFC), has developed ...

GRBs are intense bursts of gamma-ray radiation resulting from catastrophic events such as the collapse of massive stars into black holes or the merger of neutron stars. They are among the most ...

We know that regular supernovas pose no existential threat to life on Earth in the near-term. But there are other varieties ...

Gamma-ray bursts, the gigantic implosions that sometimes ... Magnetars are another type of neutron star that is even more extreme. Their magnetic fields could be up to 1,000 times that of a ...

Gamma-ray bursts typically emit as much energy in a few seconds as an entire galaxy of stars will emit in years. Think about this: a single sudden explosion, which becomes as bright as the ...

An international team of astronomers has observed extremely rapid bursts of high-energy gamma rays from a distant galaxy ... of particles and radiation from compact objects, such as neutron stars and ...

ESA’s Integral observed space for 22 years, uncovering gamma-ray bursts, black holes, and gravitational waves.

including a gamma-ray burst and a kilonova explosion seen in visible light. As the two stars spiral toward one another and merge to form a "hyper-massive" neutron star, a small fraction of the ...

In a landmark moment for astronomy and physics that helps explain the origin of the ring on your finger and key components in your cell phone, scientists announced they have, for the first time ...

PGAA is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma-ray emissions. Inaccurate and incomplete ...

A cubesat, a type of small satellite in the shape of a cube with 10-centimetre-long edges, GRBAlpha was designed as ...
