Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements,

NASA is tracking asteroid 2026 FV6, a 91-foot airplane-sized space rock set to make a safe close approach to Earth on April 13, 2026, with no threat. NASA is continuously tracking this asteroid.

The JWST discovers an impossible anomaly on TOI-5205 b and challenges everything we thought we knew about giant planets.

Artemis II’s journey around the moon, scheduled to conclude on Friday, has delivered stunning new images of our home world taken from space. Those pictures remind us that Earth has changed immensely since the last time astronauts went near the moon in 1972.

When astronomers announced Kepler-452b, they were not just adding another distant world to a growing catalog. They were pointing to a planet that orbits a star much like our own, in a region where liquid water could plausibly exist, and that looks ...

Our breakdown of 7 hidden science lessons in the stunning photo taken by an astronaut on the Artemis II mission.

An exoplanet, TOI-5205 b, which is almost as large as Jupiter, orbits a small red star. By many estimates, this red star should not have been able to form it due to the star’s mass.

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on our site, we may earn an affiliate commission.

Earth’s core may contain up to 45 oceans’ worth of hydrogen, a new study finds—an estimate that suggests that the planet formed from a gas-and-dust disk that was rich in the universe’s lightest element. The new research, published today in Nature ...
