New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.

The satellite, launched 14 years ago, will make an uncontrolled re-entry Tuesday evening. NASA puts the risk of harm to anyone on Earth at "approximately 1 in 4,200." ...

Decades of satellite observations show that Earth's vegetation forms a moving balance point across continents and seasons.

A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes far below reshape the planet's gravity field over millions of years.

— -- Astronomers on Monday reported the discovery of an Earth-like planet outside the solar system whose size and distance from its own star put it in the "habitable" zone and make for a surface ...

When we look at the solid ground beneath our feet, it's easy to assume Earth has always been this way. But our planet tells a story so extraordinary, so ...

In a landmark achievement, the James Webb Space Telescope has discovered its first exoplanet. About the same mass as Saturn, it was found in a star system about 111 light-years distant. It’s also the ...

The view of Earth from space is famously familiar—bright blue ocean, swirling gyres of white clouds, touches of terrestrial green. The luminosity of this image is the result of the sun’s rays shining ...

Leaving Planet Simple doesn't require rocket ships and interstellar “road trips” to Mars. It demands something potentially more challenging: a paradigm shift in how we understand our relationship with ...

We’re going dark. The Earth is reflecting less light than it used to, especially the Northern Hemisphere. While climate change is to blame, the reverse is also true: the planet being darker — and ...

Sixty-six light-years away, an Earth-sized exoplanet completes an orbit in under six hours, skimming around its star at nearly one-hundredth the distance that Mercury orbits the Sun. This planet is on ...
