Gamma-ray bursts are the most luminous explosions in the cosmos. Astronomers think most occur when the core of a massive star runs out of nuclear…
NASA’s Fermi Gamma-ray Space Telescope orbits Earth in this illustration. Credit: NASA’s Goddard Space Flight Center/Chris Smith (USRA) Scientists have discovered the first gamma-ray eclipses…
An artist’s impression of the gamma-ray burst GRB191221B. Credit: Urata et al./Yu-Sin Huang/MITOS Science CO., LTD Gamma-ray bursts are the brightest explosions in the cosmos,…
Artist’s conception of a gamma-ray burst caused by the violent collision of two massive neutron stars, following their inspiraling danse macabre. In addition to high-energy…
This artist’s impression shows a kilonova produced by two colliding neutron stars. While studying the aftermath of a long gamma-ray burst (GRB), two independent teams…
This animation is an artist’s impression of how the material of a star fell towards the black hole at the centre of a distant galaxy,…

Artist’s impression of GRB 211211A. The kilonova and gamma-ray burst is on the right. The blue color represents material squeezed along the poles, while the red…
An artist’s impression of a gamma-ray burst in the moment after the collapse of its progenitor star. Credit: Nuria Jordana-Mitjans/University of Bath Scientists determine that…
Astronomers think GRB 221009A represents the birth of a new black hole formed within the heart of a collapsing star. In this illustration, the black…
A small satellite galaxy (green globe on the bottom left) of the Milky Way – called Sagittarius – has been observed from Earth through giant…
Nova outbursts are apparently a source for cosmic rays. The MAGIC telescopes have observed the nova RS Ophiuchi shining brightly in gamma rays at extremely…

FAST catches a real pulse from FRB 121102. Credit: NAOC The energetic phenomena known as Fast Radio Bursts (FRBs) are one of the greatest cosmic…
Roughly a century ago, scientists began to realize that some of the radiation we detect in Earth’s atmosphere is not local in origin. This eventually…
Artist’s impression of a gamma-ray burst. Credit: Carl Knox, OzGrav-Swinburne Short gamma-ray bursts are extremely bright bursts of high-energy light that last for a couple…
A detailed look at the gamma-ray sky. Credit: NASA/DOE/Fermi LAT Collaboration Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated…
This illustration depicts a collapsing star that is producing two short gamma-ray jets. Just before a massive, collapsing star explodes as a supernova, we often…
