A team of researchers from the U.S., New Zealand, Australia and Germany has found evidence suggesting that a type of star formation near the center of the Milky Way is responsible for large gamma ray emissions, not dark matter. ...
Electromagnetic radiation is pervasive. It comes in many forms, including radio waves, microwaves and high-energy X-rays and gamma rays. But what, precisely, is it?

When trying to understand the origins of life on Earth, researchers run into a paradox: while water is an indispensable solvent for all known life forms that exist today, water also inhibits the formation of string-like chains ...
New model connects the origins of very high-energy neutrinos, ultrahigh-energy cosmic rays, and high-energy gamma rays with black-hole jets embedded in their environments.
