The space telescope spied three young stars in the nebula.

A plume of molten rock deep beneath eastern Africa is pulsing upward in rhythmic surges, slowly splitting the continent and potentially marking the birth of a new ocean, a new study reports.

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.

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.

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.

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 has delayed the launch of its Eris-1 rocket yet again, pushing back indefinitely from the previously planned July 2 date.

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.

A distant cluster of galaxies is wrapped in a vast halo of high-energy particles that could be the work of supermassive black holes or a cosmic particle accelerator.

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

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of physics.

"Its occurrence is like finding a tropical seed in Arctic ice – indicating either an unexpected local environment or long-distance transport in the early solar system."

Astronomers have discovered a galaxy that has been "frozen in time" for billions of years. Like a celestial dinosaur fossil, this galaxy could reveal the secrets of cosmic evolution.
