This envelope of radio-emitting particles — a so-called "radio mini-halo," though it isn't really mini at all — is the most distant example of such a structure ever detected.

But if those particles aren't strange enough for you, I'm here to help. There are other particles that are so rare, we're not even sure they exist. Here are five of the weirdest, rarest ...

On its surface, entanglement allows particles to communicate over vast distances instantly, apparently violating the speed of light. But while entangled particles are connected, they don't ...

Hot, fast-moving particles dominated the cosmos after the burst of energy known as the Big Bang that scientists believe triggered the universe's expansion 13.7 billion years ago.

Scientists have identified a new source of energetic particles near the Sun. These definitive observations were made by instruments aboard NASA's Parker Solar Probe, which detected the powerful ...

Physics Physicists discover that 'impossible' particles could actually be real. Every fundamental particle in the universe fits into one of two groups called fermions and bosons, but now it seems ...
