For years, astronomers have searched for the origins of ultra-high-energy cosmic rays, the most powerful particles in the universe. These energetic travelers move at nearly the speed of light, packing ...

The most powerful cosmic rays raining down on Earth may come not from distant corners of the universe but from heavy dark matter particles that annihilate themselves in our own backyard. Cosmic rays ...

Research has found black holes which 'nibble' on stars are contributing more than previously thought to the bombardment of 'cosmic rays' on Earth. Our world is constantly showered by particles ...

India’s MACE telescope has detected a gamma-ray flare from a distant quasar, marking a breakthrough in cosmic observation. The burst, originating from quasar OP 313 (B2 1308+326), is 8 billion ...

Instead, he chose to pursue physics in Cambridge, focussing on cosmic ray research. But home is where his heart lay and after receiving his PhD in 1947, he returned to India and founded the ...

DURING the last ascent of the balloon F.NM.S. (August 18, 1934), we had the opportunity of measuring with precision the intensity of cosmic rays at altitudes of about 12,000 m., 15,000 m.

Survivor is one of the most popular and enduring reality competition series currently on television. Debuting way back in 2000, it was one of the first and remains one of the longest running.

Cosmic rays are high-energy particles that zip through space at nearly the speed of light. They come from many different places in the Universe, like exploding stars (supernovae), the Sun, and even ...

ACT’s final data set delivers the most precise view of the early universe, mapping cosmic expansion and primordial gas ...

Every day, our beloved homeworld is showered in high-energy atoms called cosmic rays. Traveling close to the speed of light, these “rays” can cause havoc to electronics and other machinery ...

It's well known that huge black holes exist at the center of galaxies, including our Milky Way. But their role in cosmic ray production wasn't clear. Listen to Story Scientists have wondered where ...
