A new theory suggests fusion reactors could help scientists search for axions, mysterious particles that may explain dark ...

One of the biggest mysteries of the universe is why its expansion seems to be speeding up. Physicists have attributed it to a strange force called dark energy, but exactly how it works is largely ...

The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the first time by researchers at UCL and George ...

Scientists have identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. NASA's Parker Solar Probe is venturing closer to the ...

For decades, scientists have been trying to solve a vexing problem about the weather in outer space: At unpredictable times, high-energy particles bombard the earth and objects outside the earth’s ...

The detected cosmic ray had an estimated energy of 244 EeV, comparable to the most energetic cosmic ray ever observed (Osaka Metropolitan University/L-INSIGHT) (CN) — Researchers out of Osaka, Japan, ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Deep underground in Europe, the world's most powerful particle ...

Ever since their discovery in the 1960s, ultrahigh-energy cosmic rays have captivated scientists, who wonder where they come from. Like all cosmic rays, they are arguably misnamed: they are not “rays” ...

It might be true that there's an ultimate speed limit to everything in the Universe — the speed of light in a vacuum — but that doesn't mean there's a limit to how energetic a single particle can be.

Ultrahigh-energy cosmic rays twist and turn on their way to Earth, which has made it nearly impossible to identify the colossal monsters that create them. In the 1930s, the French physicist Pierre ...

Astrophysicists show how and when specific particles form and offers clues to questions that have troubled scientists since the 1940s. For decades, scientists have been trying to solve a vexing ...
