Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

Particle accelerator technology has crested a new wave. For the first time, scientists have shown that electrons can gain energy by surfing waves kicked up by protons shot through plasma. In the ...

Physicists at MIT have developed a new way to probe inside an atom's nucleus, using the atom's own electrons as "messengers" ...

Developed by researchers at MIT, the method uses the atom’s own electrons as “messengers” within a molecule to help probe ...

If you expanded an atom to the size of a baseball, what would it look like? And how would the inside look if you sliced it open? The nucleus is the atom’s central core and contains more than 99.9 ...

The origins of extremely high-energy particles that fill the universe—such as protons, electrons, and neutrinos—remain one of ...

CubeSat satellite activates after a powerful solar storm and discovers two new and mysterious radiation belts around Earth.

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Researchers just found out where the secret mass of protons is located. Physicists have long known that ...

We all know the story. Electrons and protons are attracted to each other. That’s why a balloon rubbed on hair clings to clothes. The electrons it gained are crying out for protons and dragging the ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...
