Scientists are building a 'beyond state-of-the-art' digital model of near-Earth space to improve forecasting of solar storms and their effects on infrastructure.

Trying to avoid satellite collisions in orbit increases the risk of future collisions in the aftermath of each avoidance maneuver, researchers have round.

Weird effects of space junk collisions could help researchers detect dangerous, hard-to-see orbital clutter.

Tech giant Rolls-Royce unveiled a mockup lunar nuclear reactor at the U.K. Space Conference in Belfast last month.

For the first time since its discovery, scientists have found stars within the Magellanic Stream, a mighty river of hydrogen gas emanating from two small galaxies in the outskirts of the Milky Way.

The James Webb Space Telescope has found water and organic carbon molecules in the vicinity of a massive, active young star.

The world's first satellite capable of detecting industrial sources of carbon emissions from space has just reached orbit  —  and it promises to be a game-changer.

Scientists have detected the presence of air pollutants from burning space junk in the upper layers of Earth's atmosphere.

Blinking streetlights could protect astronomy from the damaging effects of light pollution.

The first images from a new Earth-observing satellite reveal in unprecedented detail how temperature changes on the planet's surface.

A U.K. startup is preparing to send a satellite to space that will manufacture new semiconductor materials that could be used in electronic devices on Earth.

A collision between two ancient icy moons that may have once orbited Saturn could have given rise to the planet's iconic ring system, a new study reveals.

Asteroid Bennu is the space rock with the highest known probability of hitting Earth in the next 200 years. NASA's OSIRIS-REx mission will help us protect ourselves.

The Indian Space Research Organization began attempts to wake the Chandrayaan-3 moon lander and rover from hibernation after the two-week frosty lunar night.

Sir Brian May and NASA's OSIRIS-REx chief scientist Dante Lauretta challenge Space.com readers to photograph solar system objects to win a signed copy of their new book about asteroid Bennu.

NASA's OSIRIS-REx mission taught astronomers how little they know about space rocks. They might be only a few hundreds of feet wide, but their geology appears surprisingly complex.

The European Very Large Telescope in Chile has photographed a planet orbiting a star in a multi-star system that sits some 480 light-years from Earth.

When the OSIRIS-REx probe arrived at asteroid Bennu, it found a body that looked and behaved quite differently from what scientists had expected.

Satellites observe Hurricane Lee swirl above the Atlantic Ocean as it makes its way toward the Canadian coast for a Saturday landfall.

Satellite measurements have revealed the extent of ground movement caused by the 6.8-magnitude earthquake that struck Morocco last week, killing nearly 3,000 people.

Satellite images reveal the scale of destruction wrought by medicane Daniel on Libya, where temporary lakes and river systems sprang up across the desert landscape.

A big telescope on the moon could peer deeper into the universe than the famed James Webb Telescope and perhaps even help find life on exoplanets, scientists say.

Satellites watched as a rare Mediterranean hurricane, or "medicane," named Daniel swirled above the Sahara Desert, bringing catastrophic flooding to Libya.

New electronic devices designed to power antennas of the world's largest radio telescope are so quiet that they'll cause less disturbance than a mobile phone on the moon.

Watch ferocious hurricanes Jova and Lee spring up above the Pacific and Atlantic Ocean through the eyes of satellites.
