The traditional astrophysical recipe for life as we know it is quite simple: Get a rocky, gas-shrouded world in a “habitable zone” orbit around a star so that it’s not too hot or too cold. Then just ...

Across the observable universe, galaxies advertise themselves in radio waves for familiar reasons-magnetic fields, cosmic ...

SALT LAKE CITY — The first thing to know about potential alien invaders is that the U.S. Government no longer classifies them as unidentified flying objects. That sounds too scary. They are classified ...

Michigan State University astrophysicists are closing in on one of space science’s biggest mysteries: where the galaxy’s most energetic particles come from. Their studies uncovered a pulsar wind ...

An illustration of a young solar system immersed in high-energy cosmic rays from a nearby supernova. Unlike considering only direct injection of supernova ejecta, this process naturally explains key ...
