The ocean covers approximately 70% of Earth’s surface. It’s the largest livable space on our planet, and there’s more life there than anywhere else on Earth. Through exploration, we’re learning more about its biological, chemical, physical, and geological (地质的) aspects. Exploration lea...
Astronomers say they have discovered the largest "planet killer"-sized asteroid(小行星) in eight years, and that the huge space rock will cross the Earth's orbit.They have found three rather large asteroids, one of which, named 2022 AP7, crosses the Earth's orbit, making it a potentially...
Because massif-type anorthosites don’t form on Earth today, the new evidence linking these rocks to very hot subduction on the early Earth opens new interdisciplinary approaches for understanding how these rocks chronicle the physical evolution of our planet. “This research advances our understanding...
