Cosmic Rays
Researchers using the DAMPE space telescope have identified a shared spectral softening in cosmic rays across multiple particle types. The pattern appears at a rigidity of about 15 teraelectron-volts for protons through iron nuclei. This finding, published in Nature, offers new insight into how these high-energy particles behave in the galaxy.

Astrophysicists at Michigan State University have made progress in unraveling a century-old mystery about the origins of galactic cosmic rays. Their recent studies identified a pulsar wind nebula as a potential source behind a signal from China's LHAASO observatory. The findings, presented at the American Astronomical Society meeting, offer new insights into these high-energy particles.
