Gamma ray bursts are fleeting and can originate at any point in the sky, making it much easier for astronomers to observe ... The nearest ring is about 1,300 light-years away, and the most distant ...
Astronomers observed two neutron stars, each the remains of a dead star, colliding and turning into a black hole, a powerful event that produced a huge burst of gravitational waves — and ...
Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy -- the most distant detection of such hot gas yet. Galaxy clusters are some ...
On the morning of October 9, 2022, multiple space-based detectors picked up a powerful gamma-ray burst (GRB) passing through our Solar System, sending astronomers around the world scrambling to ...

Astronomers believe they can be found at the centre of all large galaxies, such as the Milky Way. Ultramassive black holes are rare and elusive, and their origins are unclear. Some believe they ...
Astronomers are becoming increasingly concerned about light pollution in the night sky caused by the growing number of satellites, and also space junk, in low-Earth orbit. Sunlight reflecting off ...
One of the largest black holes ever recorded has been discovered using a new technique that could spot thousands more of the insatiable celestial monsters in the coming years, according to astronomers ...
Using AstroSat and NuSTAR space telescopes, astronomers have observed an X-ray binary known as XTE J1739−285 during its recent period of bursting activity. Results of the observational campaign ...
This image shows the protocluster around the Spiderweb galaxy (formally known as MRC 1138-262), seen at a time when the Universe was only 3 billion years old. Most of the mass in the protocluster ...
On October 9, 2022, a gamma ray burst brighter than any before seen swept across Earth and space-based detectors. A team scrambled to take follow-up observations at radio wavelengths, and they ...
