Scientists still don’t know where ghostly particles called neutrinos originate. A distant galaxy could be a potential source.

In 1991, an experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power ...

An international team of scientists led by Mahidol University in Thailand has discovered a link between solar storms and ...

A neutrino from space recently plunged into the Mediterranean Sea with an energy that blows all other known neutrinos out of the water. Packing a punch of some 220 million billion electron volts, this ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...
