Tiny particles bubbling up from the tops of melting sea ice into the Arctic sky may be a key, understudied element of cloud formation in that climate-sensitive region. Ice-nucleating particles can ...

In November, scientists arrived at the South Pole in planes outfitted with skis to pull off a construction project seven years in the making. They had a short summer window – November to early ...

Clouds form when water vapor – an invisible gas in the atmosphere – sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, ...

Scientists working at the South Pole have completed a major hardware expansion of the IceCube Neutrino Observatory, installing new sensor strings deep in Antarctic ice during the 2025-2026 austral ...

NASA's most ambitious Arctic voyage to date has revealed surprisingly high concentrations of ice particles in clouds over Greenland, a clue that may help explain why Arctic ice is melting even faster ...

Scientists have identified traces of radioactive stardust preserved in Antarctic ice, directly linking Earth to debris produced by ancient stellar explosions. The discovery involves iron-60, a rare ...
