Scientists in China identify shock drift acceleration as the key process behind cosmic rays' high energy, resolving a major ...

These high-energy particles are linked to powerful cosmic events such as exploding stars and the environments around black ...

A new approach suggests that a tiny spin of the universe throughout space might reconcile those conflicting numbers. If the ...

such as near black holes or during cosmic events like the collision of neutron stars, the effects of gravity can be significantly different and would require Einstein's theory of general ...

It took a full year of testing, experimenting and calculating for them and another group of researchers at Princeton to explain the phenomenon: It was cosmic ... the Big Bang theory, first ...

These cosmic strings could stretch the length of the universe. A piece of this string only 1.6 kilometers long would weigh more than the earth. Others have added to the theory: That symmetry still ...

One approach looks far back in time, using the cosmic microwave background—the ... their results create a 4.8-sigma tension with the standard theory, a statistically significant mismatch.

Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.

A dramatic cosmic event is winding up to occur right in our backyard. Astronomers have spotted a pair of stars bound for collision, located just 150 light-years away. When the pair impact, they will ...
