Three years ago, in the waters of the Mediterranean Sea, the passage of an "ultra-energetic" cosmic neutrino was observed—the ...

A team of astronomers led by Matteo Cerruti of Paris Cité University reports multi-wavelength evidence for a repeating, roughly 3-year modulation in the gamma-ray output of the blazar S5 1044+71, a ...

The KM3NeT collaboration has traced the most energetic neutrino ever recorded back to a likely source: blazars, the supercharged jets fired by supermassive black holes directly toward Earth. The ...

On October 9, 2022, telescopes detected one of the brightest gamma-ray bursts ever! A gamma-ray burst (GRB) is an extremely energetic and bright explosion observed from distant galaxies and can last ...

A miniature cubesat built by Eastern European astronomers has been detecting gamma-ray bursts since 2021. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

White and green electromagnetic detectors surround mounds of dirt covering instruments to detect muon particles originating from outer space at the Large High-Altitude Air Shower Observatory (LHAASO) ...
