Study of ancient craters shows slow buildup of ice in permanent shadows rather than sudden delivery by a comet.

A new experimental design suggests that scientists could exchange energy between laser beams and gravitational waves to prove that gravity is made of tiny individual particles called gravitons.

Researchers have observed a distant black hole twisting the fabric of the universe as it shreds a star, confirming a century-old prediction made by Albert Einstein about gravity.

Neutron stars might be surrounded by clouds of tiny particles called axions, and this might help explain dark matter.

For the first time, a rocky habitable-zone exoplanet shows atmospheric variability. Confirmed on LHS 1140 b, this Science-published milestone elevates the super-Earth as a prime JWST target for life biomarkers.

This finding shows complex chemical reactions in Saturn's moon's underground ocean, increasing the potential for life and supporting plans for a future space mission.

A major gift enables MIT to support a powerful new observatory and boost U.S. leadership in exploring the universe.

Physicists develop FROSTI to enhance LIGO's precision in observing cosmic events by controlling powerful laser distortions.

These dim stars make it easier to spot the infrared glow of energy-harvesting megastructures, bypassing dusty false alarms and boosting SETI’s search efficiency.

NASA's Webb Telescope finds a 13-billion-year-old supernova, the earliest ever seen, revealing surprising similarities to modern star explosions and detecting its ancient host galaxy.
