A groundbreaking new survey from China’s LHAASO observatory has unveiled powerful ultrahigh-energy gamma-ray emissions across ...

There are strange radio waves miles above Antarctica’s ice and scientists aren’t exactly sure what’s causing them. The radio pulses could “hint at” new particles or interactions between known ...

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

Scientists are trying to solve a decade-long mystery by determining the identity of anomalous signals detected from below ice ...

High above the windswept Ross Ice Shelf, a helium balloon the size of a football stadium drifts in the polar twilight. Slung ...

A NASA experiment has picked up bizarre cosmic whispers—and they’re defying everything we thought we knew about particle physics.

STRANGE radio pulses detected roughly 25 miles (40km) above Antarctica could be the mark of a new cosmic particle, according to a new study. This rare signal was first detected by the Antarctic ...

The icy, desolate landscape of Antarctica, a continent synonymous with extreme cold and scientific isolation, might be harboring a secret that could fundamentally alter our perception of the cosmos.

Most cosmic rays are already high in energy, but some go even further. These ultra-high-energy cosmic rays (UHECRs) carry more than 10¹⁹ electron volts of energy.
