Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest

Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...

Phys.org / Mercury's crust points to deeper, hotter volcanic origins than expected

The evolutionary histories of Earth and Mercury differ fundamentally. The smallest planet, closest to the sun, likely began cooling early on, much like a setting pudding: As early as about 1 billion years after its formation, ...

Phys.org / Geomagnetic superstorm shook GPS accuracy across the US—its timing may have averted agricultural losses

On Nov. 11, 2025, Earth experienced a severe geomagnetic storm triggered by solar flares and coronal mass ejections from an active sunspot region. While this kind of storm brings beautiful auroras admired in many areas around ...

Phys.org / Major polluters are worsening the Western US water crisis: A new way to measure who's responsible

Climate change was once something scientists warned us about, and now it's a reality we are living in. In California's Central Valley, about one-third of climate-related groundwater loss between 2003 and 2024 can be attributed ...
