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

SAN FRANCISCO – Muon Space will deliver space weather data to the U.S. Space Force under a $400,000 contract option announced July 11. Under the original $2.8 million contract with Air Force Life ...

Muon tomography, or muography, is the practice of using muons generated by cosmic rays interacting with Earth’s atmosphere to image structures on Earth’s surface, akin to producing an X-ray. In lieu ...

A prototype of a device that could someday detect nukes through layers of steel just passed its first test. The detector, which uses technology that was developed for particle physics experiments at ...

A mysterious magnetic property of subatomic particles called muons hints that new fundamental particles may be lurking undiscovered. In a painstakingly precise experiment, muons’ gyrations within a ...

A subatomic particle called the muon is wobbling far more than leading physics models can explain. Its unusual behavior could be evidence of a fifth force of nature or a new dimension. Scientists ...

The muon—the short-lived cousin of the electron—could be the key to understanding relationships between other fundamental particles. And it holds a mystery all its own. In the 1930s, scientists ...

A Falcon 9 lifts off June 12 on the Transporter-8 rideshare mission. Credit: SpaceX webcast SAN FRANCISCO – Muon Space, a Silicon Valley startup building a climate-monitoring constellation, sent its ...

Muons might not behave as expected. But scientists can’t agree on what to expect. By taking stock of how the subatomic particles wobble in a magnetic field, physicists have pinned down a property of ...

The Muon g-2 experiment (pronounced “gee minus two”) is designed to look for tantalizing hints of physics beyond the Standard Model of particle physics. It does this by measuring the magnetic field ...
