How common are Earth-like planets in the universe? When I started working on supernova explosions, I never imagined that my ...

Some of the most energetic cosmic rays in the galaxy may come from a surprisingly small source. If Max Planck Institute for Astrophysics researcher Laura Olivera-Nieto and her colleagues are right, ...

So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and helium, and fluctuations of energy and matter set into motion the formation of ...

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 ...

The “Oh-My-God” particle has a new companion. In 1991, physicists spotted a particle from space that crashed into Earth with so much energy that it warranted an “OMG!” With 320 quintillion electron ...

Scientists have detected the most powerful cosmic ray seen in more than three decades. But the exact origin of this turbocharged particle from outer space remains a mystery, with some suggesting that ...

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 ...
