The Phoenix Cluster's central galaxy is about 5.8 billion light-years away and should be mostly done with star formation. Many galaxy clusters have a region of hot gas in the intracluster medium (ICM) ...

Using an observatory located deep beneath the Mediterranean Sea, an international team has detected an ultra-high-energy ...

Three and a half kilometers beneath the Mediterranean Sea, around 80km off the coast of Sicily, lies half of a very unusual ...

The particles that aren't swallowed can be shot out at extreme speeds. These "active galactic nuclei" are another way that the universe could create extreme neutrinos. Third, the neutrinos could be ...

Three and a half kilometers beneath the Mediterranean Sea, KM3NeT, a deep-sea telescope, detected the most energetic neutrino ever found, marking a major advancement in understanding extreme cosmic ...

"History shows us that whenever you do open a new 'energy window,' you never really know what you're going to find. It's completely unexplored." ...

Neutrinos are very mysterious particles,” says Damien Dornic, one of the co-authors of a new paper published February 12 in ...

A deep-sea detector glimpsed a particle with 220 million billion electron volts of energy — around 20 times as energetic as any neutrino seen before.
