Monster black holes shooting jets of gamma-ray radiation right at us have been spotted farther away than ever before, dating back to when the universe was nearly one-tenth its current age. The five ...

A single particle cut through the Mediterranean in February 2023 carrying an almost absurd amount of energy. Detected deep off the coast of Sicily by the KM3NeT/ARCA neutrino telescope, the neutrino ...

Astronomers are actively hunting a class of supermassive black holes throughout the universe called blazars thanks to data collected by NASA’s Wide-field Infrared Survey Explorer (WISE). The mission ...

Blazars and quasars are both subclasses of active galactic nuclei (AGN). The accretion of gas onto a galaxy’s central supermassive black hole powers AGNs. Both appear as bright, variable point sources ...

Fast-acting astronomers have captured blazars in the act of spewing out material, providing new insights into these powerful phenomena. Blazars are found in the middle of galaxies where supermassive ...

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 ...

Blazing brightly: NASA illustration of a blazar, with one of its jets beaming straight towards Earth. (Courtesy: NASA/Goddard Space Flight Center Conceptual Image Lab) An international group of ...
