An underground ocean refers to vast amounts of water stored inside Earth’s mantle rock. It’s not a flowing body of water like a lake or sea.

Beneath Ethiopia, the Earth’s mantle is pulsing like a slow, steady heartbeat, slowly tearing Africa apart and laying the ...

Up to that point, people had only drilled into this type of rock to a depth of about 200 meters (0.12 miles), Lang said. When Lang and the team surpassed 200 meters they were already extremely ...

Researchers mapped a pulsing mantle plume under Afar that channels molten rock upward, stretching Africa’s crust until it ...

Evidence of a deep global ocean beneath the crust of Saturn's moon Mimas—sometimes called the "Death Star"—has surprised astronomers because it's such an unlikely place to find one.

There's a whole ocean's worth of water locked in that rock, but the problem is that it's inaccessible. According to the team, the layer is 11.5 to 20 km (7 to 13 miles) beneath the surface, which ...

A new study of Saturn's 'Death Star' moon Mimas finds evidence of a young, underground ocean that may be hospitable to early forms of life. When you purchase through links on our site, we may earn ...

They say reactive basalt rock across the planet could turn CO2 into rock at the bottom of the ocean. Offshore carbon-capturing factories may help fight climate change in the future — for a steep ...

"Our findings confirm there was an explosion, possibly due to a gas-compressed rock, which released energy that equated to five of the largest underground nuclear explosions conducted by North ...

In 2005, NASA's Cassini spacecraft first discovered towering plumes of water vapor erupting from the moon's frozen surface, for instance, and it was later theorized that these geysers come from a ...
