MethaneSAT, the first satellite made by an environmental nonprofit organization, was designed to monitor some of the world's largest industrial contributors of greenhouse gas emissions. Now, without power, the spacecraft's mission has abruptly ended.

As the sun grew hotter, so did Mars, prompting much of its atmospheric carbon dioxide to rain out and ultimately get locked up in rocks.

Astronomers using the European Space Agency’s Cheops mission have caught an exoplanet that seems to be triggering flares of radiation from the star it orbits. These tremendous explosions are blasting away the planet’s wispy atmosphere, causing it to shrink every year.

Some planets take the expression "you're your own worst enemy" to the extreme — triggering stellar flares from their own parent stars by being too clingy.

Space.com sat down recently with retired NASA astronaut Terry Virts to talk about space, politics and his run in Texas for a seat in the U.S. Senate.

Two meteorological missions – Meteosat Third Generation Sounder-1 (MTG-S1) and the Copernicus Sentinel-4 mission – have launched on board a SpaceX Falcon 9 from Cape Canaveral in Florida, US.

Our Red Planet explorers may encounter a peculiar threat.

SpaceX launched 27 Starlink satellites into low Earth orbit today (July 2), on the 500th Falcon 9 rocket launch in the company's history.

Auroras may be visible from Alaska to New York as an incoming solar storm could spark geomagnetic storm conditions overnight.

Astronomers have discovered the first evidence of a white dwarf wiped out by a double-detonation supernova, also providing space-lovers with stunning eye-candy.

Update July 2, 3 a.m. EDT: SpaceX landed its first stage booster on the droneship, ‘A Shortfall of Gravitas.’

The second of the Meteosat Third Generation (MTG) satellites and the first instrument for the Copernicus Sentinel-4 mission lifted off at 23:04 CEST on Tuesday, 1 July. The satellite is now on its way to monitor Earth’s atmosphere from an altitude of 36 000 km. From this geostationary orbit, the missions can provide game-changing data for forecasting severe storms and air pollution over Europe.

A SpaceX Falcon 9 rocket launched the MTG-S1 weather satellite for EUMETSAT today (July 1), then came back down to Earth for a landing on a ship at sea.

Cosmic archeologists have used the James Webb Space Telescope to excavate ancient disk galaxies that tell the story of how the Milky Way and other modern galaxies evolved.

The phenomenon is created by the shifting play of light and shadow over the lunar surface.

The Australian company Gilmour Space is back at the launch pad with its Eris-1 rocket, preparing for the country's first orbital launch on July 2.

A European satellite designed to augment both weather monitoring and assessments of air quality and pollution for Europe and North Africa is preparing to take flight from Florida on Tuesday evening.

American companies launched 21 commercial space missions in June 2025, which was a new record for a single month, according to the Federal Aviation Administration.

The Mars rover captured images of low ridges called boxwork patterns, which appear like spiderwebs from space.
