Earth is set to experience one of its shortest days ever recorded as the planet's rotation continues its unexpected acceleration. Following Wednesday's notably brief day, which clocked in at 1.3 milliseconds shorter than average,

Despite geopolitical tension and national budget woes, one message rang out loud and clear at Living Planet Symposium 2025: Earth science is a global mission. ESA has long fostered partnerships with NASA, JAXA, ISRO and many other space agencies and those collaborations continue to underpin the progress being made today.

In all, there are only 400 known Mars rocks on Earth, comprising less than 1% of all known space rocks on the Blue Planet.

How did Earth, alone among the solar system's rocky planets, become the home for life? How, among all this frigid lifelessness, did our planet become warm, hospitable, and life-sustaining? The answer to these questions is complex and multi-faceted,

July 9, 2025, saw the Earth spin through one of its shortest days on record a fleeting, nanosecond instant that passed unnoticed by most, but sent ripples within the domain of high-precision timekeeping.

A just-issued monthly report has found the first six months of 2025 are pacing just behind the record warm year of 2024. Here are the findings and what they mean.

Over the past two centuries, humans have quietly nudged the very axis of our planet. As thousands of dams have been built across the world, Earth's poles have tilted by over 1 meter (3 feet). The movement of Earth's poles can be traced to two great waves of dam construction: first in North America and Europe during the 19th and early 20th centuries,

Stars are known for being some of the largest objects in the cosmos, with some clocking in at upwards of 1,700 times the size of our Sun. However, they’re not all like that and recently astronomers detected an Earth-sized planet orbiting a star that is only around the size of Jupiter.
