Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward ...

Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the ...

Asteroids are ancient remnants of the solar system's birth. They orbit the Sun and occasionally pass near Earth. Tracking them helps scientists study space and potential risks. NASA uses radar and ...

"It's like a lid on top of its convective mantle." But without any other nearby planets exhibiting plate tectonics to compare Earth's system to, it's hard to know precisely what causes a planet to ...

They developed a 3D model that simulates how the solar system's orbital architecture may have evolved differently with the formation of a planet that is at least twice the size of Earth's mass—a ...

SpaceX launched two Earth-imaging satellites today (Feb. 4), further building out Maxar Technologies' sharp-eyed WorldView Legion constellation. A Falcon 9 rocket carrying the WorldView Legion 5 ...

If the near-Earth asteroid Bennu were to collide with Earth in the future, the space rock could cause substantial global damage, even though it’s a fraction of the size of the asteroid that ...

“Hell on Earth” might not just be an exaggeration ... when Hekla erupted with a Volcanic Explosivity Index (VEI) of 5 — the same rating as Mount St. Helens’ deadly 1980 eruption.

The meteorite was identified as billions of years older than Earth itself. The cosmic element offers valuable insights into the early formation of the solar system. Due to its unique composition ...

It may sound apocalyptic, but a newly detected asteroid nearly the size of a football field now has a greater than one percent chance of colliding with Earth in about eight years. Such an impact ...

NASA’s OSIRIS-REx mission uncovered a cosmic connection between asteroid Bennu and Earth’s Searles Lake. Both contain minerals formed by evaporating salty water, hinting that Bennu’s parent body once ...

What’s remembered today is the more general question it inspired: Given a central sphere, how many identical spheres can be arranged so that ... come up with clever new constructions in dimensions 5, ...
