On July 15, a solar filament erupted from the Sun’s upper left side, ejecting a powerful blast of plasma and magnetic fields into space. The resulting explosion was so massive that it seared a deep, fiery scar of hot plasma and debris onto the star’s visible surface. While filament eruptions aren’t uncommon, astronomers had already been watching an unusually large …

Astronomers have discovered that radiation emitted by a rapidly spinning neutron star, or “pulsar,” is dominated by the impact of its powerful particle winds — and not by the material it strips from a companion star. The pulsar in question is PSR J1023+0038 (J1023), which sits in a binary system located 4,500 light-years away from Earth. This binary consists of …

Scientists have discovered a long-lost landscape that’s been preserved beneath the Antarctic Ice Sheet for 30 million years. Erosion by ancient rivers appears to have carved large, flat surfaces beneath the ice in East Antarctica between 80 million and 34 million years ago. Understanding how these features formed, and how they continue to affect the landscape, could help refine predictions …
