"A modern five-day forecast is as accurate as a one-day forecast in 1980."
Hawaii is the most isolated volcanic hot spot on Earth, far away from any plate boundary.
One possible vision of the distant future.
All American and European eels originate in the same place.
It could one day fuel nuclear fusion reactors.
The monsoon rains were not always so reliable.
Recent research suggests that Earth’s magnetic field bounced back just as complex life was starting to emerge on our planet.
Asteroid collisions aren't always bad.
"The surface is no longer a record of every impact the moon has ever had, because at some point, impacts were erasing previous impacts."
The length of a day oscillates slightly every six years. This was a surprising discovery made last decade. We might now know why.
Fossils of Australopithecus in a South African cave are one million years older than previously thought. This challenges the consensus that humans first evolved in East Africa.
A new study of Martian dust gives insights into the ancient Martian climate. The findings hint at a wetter world.
The answer may lie in the particular way sand forms on Titan.
Data from the Zhurong rover suggests the Red Planet was wet more recently than we thought.
We have long thought that Pluto was completely frozen solid, but the discovery of cryovolcanoes challenges that assumption.
Volcanic activity caused the end-Triassic mass extinction 200 million years ago. The dinosaurs survived and rose to dominance.
Ancient helium-3 from the dawn of time leaks from the Earth, offering clues to our planet’s formation. A key question is where it leaks from.
Scientists have known blobs existed for a long time, but how they have behaved over Earth’s history has been an open question.
Scientists across a range of disciplines have helped solve Darwin's dilemma.
Due to a crust of carbon, the absence of oxygen, and constant bombardment from meteorites, the planet Mercury may be littered with diamonds.
Where the prime meridian meets the equator, a non-existent island captures our imagination — and our non-geocoded data.
In the Saudi Arabian desert, the Al Naslaa rock formation looks completely unnatural. Its perfectly vertical split remains a mystery.
Gigantic ranges called "supermountains" formed twice in Earth's history, and they may have had a profound influence on evolutionary history.
The natural wonders of Mauritius include the spectacular sight of an underwater waterfall. Here's the science of how it works.
Lake Baikal holds nearly one-fourth of Earth's fresh surface water and is the most scientifically interesting lake on our planet.
We know more about the universe than what is beneath our feet. But Earth's mantle holds subtle clues about our planet's past.
Dating of volcanic ash suggests the remains are at least 230,000 years old.
Purely physical and chemical processes can deceive us into thinking that life is present, when it actually is not.
Until now, researchers believed davemaoite could never be found on Earth's surface.
