Astronomers are trying to understand a mysterious cosmic explosion that the Einstein Probe spacecraft spotted in April last year.

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

That gamma rays under certain experimental conditions appear to become less penetrating as they pass through matter was shown by Dr. Gray in 1913. Recently it has been shown by me (Phil.

The 25 ground-based and orbiting telescopes that comprise the EHT saw the outburst as high-energy light called gamma rays. Not only was this the first time M87* had flared since 2010, but the ...

Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it ...

The recent detection of a cosmic explosion by the Einstein Probe is stirring excitement among space watchers everywhere.

Recently, China’s Tianguan satellite (Einstein Probe Satellite) detected a gamma-ray burst EP240315a. It's the first time to ...

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...

As a result, they detected increased gamma-ray activity from this source, including a strong outburst. The finding is reported in a research paper published on the arXiv preprint server.
