Reactors designed to produce energy from the fusion of atoms could have an unexpected scientific side benefit. An ...

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 ...

Conditions can get rough in the micro- and nanoworld. For example, to ensure that nutrients can still be optimally ...

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 ...

The findings could help researchers predict dangerous space weather. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists may have ...

"History shows us that whenever you do open a new 'energy window,' you never really know what you're going to find. It's completely unexplored." When you purchase through links on our site, we may ...

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 ...

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 ...
