A single pancake may capture where you poke a straw into it, but it takes a whole stack to record the straw’s direction. Similarly, Kobe…
The U.S. Naval Research Laboratory and the Fermi Large Area Telescope Collaboration have discovered nearly 300 gamma ray pulsars, advancing pulsar research and contributing to…
Northwestern University researchers have developed simulations showing that long gamma-ray bursts, previously thought to be exclusive to massive star collapses, can also occur from neutron…
New research using computer simulations and astronomical data has uncovered that some long-lasting gamma-ray bursts (GRBs) are caused by cosmic mergers forming black holes, challenging…
ESA’s Integral space telescope detected an unprecedented gamma-ray burst from a distant exploding star, causing significant disturbances in Earth’s ionosphere. This event, the brightest and…
Researchers discovered the highest-energy light ever observed from the sun, known as gamma rays, which was brighter than previously anticipated. This finding, derived from six…
Researchers from the Purple Mountain Observatory and the Italian National Institute for Astrophysics have developed a new way to measure UV sources using the Swift/UVOT…
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…

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,…

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…
