A new method to exploit Gamma-Ray Bursts (GRBs), the most energetic explosions in the universe, as independent measurements of the Universe’s expansion rate has been discovered in optical wavelength.

A flash of high-energy light from deep space has forced astronomers to rethink what they thought they knew about the most ...

Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, ...

Telescopes operating up and down the electromagnetic spectrum have confirmed that the longest gamma ray burst (GRB) was ...

A seven-hour gamma-ray burst, GRB 250702B, stuns astronomers and hints at powerful new cosmic engines still unknown to science.

Astronomers have observed the longest-ever gamma-ray burst — a powerful, extragalactic explosion that lasted over seven hours ...

Aug. 5 (UPI) --The collision of two distant neutron stars released one of the most powerful short gamma-ray bursts ever recorded, scientists say. The collision marked the first time scientists have ...

ESA’s gamma-ray satellite, Integral, is fully operational. Today Integral’s first ground-breaking images of the high-energy Universe were presented in Paris, France. Astronomers call such initial ...

A huge surge of gamma-ray energy from space caused electric currents to flow through the surface of the Earth on October 9, scientists have said. This gamma-ray burst, named GRB221009A, is the ...

A pancake stack of radioactivity-sensitive films carried through the sky by a balloon was able to take the world's most accurate picture of a neutron star's gamma ray beam. To achieve this, Kobe ...
