An illustration of an asteroid colliding with Earth.

One of the biggest meteorite crashes in Earth’s history flung debris across 3 continents 800,000 years ago. Scientists finally found the crater....

Scientists may have solved the geological mystery of what happened to an 800-year-old meteorite that blanketed 10% of the Earth in debris.
Tourists explore White Island on July 9, 2019 in Whakatane, New Zealand.

At least 16 people are dead after a New Zealand volcano erupted. Experts say the disaster was not predictable, despite warning signs.

Geologists and tourists knew that the volcano that erupted last week on New Zealand's White Island was active. It last erupted in 2016.
A map of where the Greater Adria continent was located 140 million years ago.

A lost 8th continent is hidden nearly 1,000 miles under Europe, new research shows. Scientists named it ‘Greater Adria.’

Millions of years ago, the supercontinent Pangea broke up into land masses that became modern-day continents. One continent was buried under Europe.

Incredible videos show California’s biggest earthquake in 20 years rippling across North America

Hundreds of seismometers recorded California's magnitude 6.4 earthquake. Animations created from the data show how its energy moved across America.
The mysterious lunar lump exists below the surface of the lunar South Pole-Aitken Basin (in blues and purples).

Scientists have discovered a mysterious lump on the moon’s far side, and it’s 5 times bigger than Hawaii’s Big Island

Gravitational data suggest the anomaly is the metallic core of a giant asteroid that's hiding 190 miles beneath the lunar South Pole-Aitken Basin.

Scientists have discovered a cave that may be the largest in Canada, and it’s never been seen before by humans

A massive, unexplored cave in British Columbia could be the largest in Canada. Researchers surveyed the enormous cave in September.

NASA’s new Mars mission just landed — and it could reveal why Earth is habitable but the red planet is not

While online shoppers celebrated Cyber Monday deals, a group of NASA scientists cheered the successful landing of the $830 million InSight Mars probe.
An illustration of NASA's InSight probe attempting to land on the surface of Mars

NASA’s InSight probe must survive ‘7 minutes of terror’ to land on Mars. If it does, here are some incredible discoveries the robot ...

NASA's InSight Mars mission will attempt unprecedented science on the red planet, including probing Mars' temperature and listening for Mars quakes.
The moon as seen by astronauts in space.

The moon has ice on its surface in hundreds of places — and it could be the ‘first step in building a space economy’

The moon's cold, dark craters near its north and south poles contain water ice directly at the surface, a new study confirms. If the deposits are large enough, people or robots could harvest the water, split it into hydrogen and oxygen, fuel up rockets, and launch a new era of space exploration.
Diamonds are less rare than you probably thought.

There are over a quadrillion tons of diamonds lurking 100 miles below the Earth’s surface, according to scientists

Scientists used sound waves to uncover a cache of more than a quadrillion tons of diamonds deep below the Earth's surface. The diamonds, however, are impossible to mine — they're located far deeper than any drills are capable of reaching.
