Scientists are seeking answers after a telescope in Utah detected the most powerful cosmic ray seen in more than three decades.

Kinky particles: the GRAPES-3 experiment in Ooty, India depicted with a simulated cosmic ray shower. The inset shows the cosmic ray proton spectrum measurement by GRAPES-3 along with observations by ...

The source of this extragalactic cosmic ray, detected on May 27, 2021, remains an enigma, as its incoming direction does not align with any known astronomical objects.

Space scientists have detected an extremely rare, ultra-high-energy particle that they believe traveled to Earth from beyond the Milky Way galaxy.

To reach this conclusion, scientists studied millions of data points captured by a cosmic ray detector on the ISS.
