For decades, a sharp kink in the energy spectrum of particles raining down from space has taunted astrophysicists, hinting at powerful engines in our Galaxy but refusing to reveal their identity. Now ...

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...

A seven-hour gamma-ray burst, GRB 250702B, stuns astronomers and hints at powerful new cosmic engines still unknown to science.

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...

Michigan State University astrophysicists are closing in on one of space science’s biggest mysteries: where the galaxy’s most energetic particles come from. Their studies uncovered a pulsar wind ...

Cosmic rays are high-energy particles that constantly bombard Earth from space and are influenced by the sun's magnetic activity. When the sun is active, fewer of these particles reach Earth; when the ...

BEIJING -- Scientists using China's Large High Altitude Air Shower Observatory (LHAASO) found that black holes, devouring material from their companion stars and producing jets, act as powerful ...

Archaeologists have dated the lakefront Neolithic (7000–3200 b.c.) settlement of Dispilio in northern Greece using a method that involves detecting evidence of bursts of cosmic radiation in ancient ...

When I was four years old, my pregnant mother drove my sister and me out to Dugway Proving Grounds in Utah to visit my father ...

Cosmic rays, high-energy particles that travel through space, have puzzled scientists for decades. One particular feature of their energy spectrum—the “knee”—has long remained a mystery. Recent ...

A joint team of Chinese and international scientists released the latest scientific results from China's Large High Altitude Air Shower Observatory (LHAASO) on Sunday. The data solved a decades-old ...

What mechanism accelerates cosmic rays to the 3 peta-electron-volt (PeV) range — over 1,000 times the energy of the world's most powerful man-made particle accelerators — causing a sharp decline in ...
