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, ...

Polar ice melt caused by climate change is slowing the rotation of our planet at a rate never seen in the last 3.6 million ...

It only takes one close encounter with a lightning strike to get the full sense of its power. At around 1 gigaJoule of energy ...

An exoplanet, TOI-5205 b, which is almost as large as Jupiter, orbits a small red star. By many estimates, this red star ...

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

Dying stars may be wiping out nearby giant planets as they expand into red giants. Astronomers found that these close-in planets become increasingly rare around more evolved stars, suggesting many ...

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 ...

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 ...

A distant star has just been caught in the act of destroying one of its own worlds, a violent finale astronomers have long predicted but never directly seen. The event offers a preview of the kind of ...

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in the direction of Africa over the past decade. When you purchase through ...

Amid the cold silence of the main belt, a giant rock drifts through space. It has existed for billions of years unchanged, but today, it will be irrevocably broken. Another rocky object hurtles toward ...
