For the first time, researchers looking at a black hole have spotted a naturally occurring particle accelerator that's speeding up the cosmic rays bombarding our planet.
Gamma rays and ultra-high-energy cosmic rays are filling a huge area of the sky. An astronomer calls it a "total conundrum."

Cosmic rays have been suspected of affecting an election in Belgium, brakes on Toyota vehicles, and possibly even the Samsung Galaxy Note 7's battery.

The origin of the universe's most powerful cosmic rays, or high-speed particles, has been difficult to determine since their discovery about 100 years ago. Astronomers recently used ghostly particles called neutrinos to verify that rapidly spinning black holes called blazars emit cosmic rays.
Pilots and flight attendants get pummelled by cosmic rays and solar storms while keeping you safe and serving you drinks.
Physicists used cosmic rays to penetrate the pharaoh Khufu pyramid's thick rock and discover a void that's about the length of two semitrailers.
Based on a study in mice, the risk of cancer on Mars could be twice as high as researchers previously thought.
New research shows that even ordinary levels of cosmic radiation can have a disruptive effect on our personal devices — it doesn't even take a solar storm.
An explosion close enough to Earth would bombard us with radiation, causing mutations as well as potentially catastrophic climate shifts.
This very second, high energy particles from outer space are racing towards us at nearly the speed of light.
This very second, high energy particles from outer space are racing towards us at nearly the speed of light.
And could be at higher risk of radiation-related health effects.
It's baffled scientists for decades.
Track cosmic rays with your phone.
Scientists inch closer to detecting dark matter.
From neutrinos to chimps.
Sensors buried below the ice may help scientists figure out where the high-energy rays that speed through space are born.

We, too, may be living in a simulation generated by an all powerful computer. Cosmic rays could tell us if we are living in the matrix, one physicist suggests.
