Geology
The Earth was humming because a huge underwater volcano was forming
Buzzing temblors marked the formation of a supervolcano -- but there is no risk yet.
Venus might still be volcanically active, according to its infrared emissions
Earth's sister planet might also enjoy a bit of volcanism.
A new study says oxygen buildup on Earth was “inevitable,” and maybe on other planets, too
The findings offer renewed hope of finding oxygen on alien worlds.
World’s deepest point on land found hidden in Antarctica
A trough beneath Denman Glacier is the deepest continent point in the world, measuring more than 2 miles beneath sea level.
NASA maps ice water reserves inches below Martian surface
A new map of water ice trapped beneath Mars' surface could inform astronauts where they should land.
First geological map of Titan reveals varied, intriguing geology
Titan is a lot like the Earth... except it's nothing like the Earth.
Radar reveals ancient ‘ghost’ human footprints — in mammoth footprints
Researchers have used ground-penetrating radar to find overlapping tracks from 12,000 years ago.
The Nile is 30 million years old — and held together by movements in the Earth’s mantle
Ancient Egyptians believed the Nile was eternal -- and they may have been on to something.
Where Does the Carbon Go When Permafrost Coasts Erode?
Arctic coastlines have not been considered carefully in carbon cycles for long, but new research suggests that eroding permafrost may emit more greenhouse gases than previously thought.
Giant geode large enough to fit people inside grew slow and steady
Temperature fluctuations, maybe from climate or maybe from geothermal systems, amplified a natural process that grew the crystals.
Researchers may have spotted the smallest dwarf planet in the solar system
Small but significant.
Underwater volcanoes can produce stadium-sized bubbles
Some bubbles were up to 750 feet (228 meters) across.
Salt lake Mars: Red planet had salty lakes billions of years ago
Mars' past seems to be more and more interesting.
Io volcano is surprisingly predictable, and will likely erupt this month
Pop goes the volcano.
Scientists detect climate “smoking gun” signature in rivers
For decades, researchers have been trying to detect the influence of climate on river formation -- now, they've done it.
Scientists reconstruct the first 24 hours of dinosaur-killing asteroid impact
Molten rock shooting for the moon, huge tsunamis hundreds of feet tall, and global wildfires were triggered immediately after the impact.
Key variable used to study Mars’ ancient atmosphere varies during the day
This used to mess up our calculations, but now we understand why.
