You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

The CosmicWatch device costs only $100 to make, making it accessible for both high school students and spacecraft operators.

Particles raining down from space offer 3-D views inside swirling tropical storms. Muons created from cosmic rays that smash into Earth’s upper atmosphere have revealed the inner workings of cyclones ...

The windy and chaotic remains surrounding recently exploded stars may be launching the fastest particles in the universe. Highly magnetic neutron stars known as pulsars whip up a fast and strong ...

New research puts forward compelling new evidence that dark matter interacts with cosmic "ghost particles" called neutrinos.

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from outside ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

"I've always been fascinated by how we extract information from reality — even when we can’t fully define what reality is." When you purchase through links on our site, we may earn an affiliate ...

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of ...

Researchers recently detected an "ultra-high-energy" cosmic ray, which is the most powerful since the famous "Oh My God" particle was detected in 1991. They have no idea where it came from. When you ...

A stream of high-energy particles from a distant supernova explosion may have caused a packed passenger jet to suddenly lose altitude in late October, forcing an emergency landing. The incident took ...
