Mars’ Mysterious Streaks Lose Their Watery Allure

A groundbreaking study using machine learning has revealed that the dark streaks once thought to indicate liquid water on Mars are actually the result of dry, dusty processes — reshaping the way we explore the Red Planet.

Craters That Reveal What Mars Is Hiding

Debris blasted from Martian craters is revealing what's hidden beneath the surface — from glaciers to ancient lakebeds — using just satellite images.

Magnetic Chaos of the Milky Way Comes into Focus

A supercomputer-powered simulation reveals how magnetic turbulence shapes the Milky Way — from solar wind to star birth.

When the Universe Wiggles

A new study proposes a groundbreaking way to detect gravitational waves — by watching distant quasars “wiggle” in the sky — potentially unlocking the three-dimensional nature of spacetime ripples and rewriting what we know about gravity.

Magnetar Flares May Forge the Universe’s Heaviest Elements

Flares from ultra-magnetized neutron stars, or magnetars, may be key contributors to the universe’s supply of heavy elements like gold and platinum, according to a new study from Ohio State University.
