If human beings want to survive on the other planets for a long time, they must first find or set up a safe, stable, and long-term shelter. Lunar lava tubes are geological structures on the moon ...

A Canary Islands volcano pushed rivers of molten lava through the earth. Now scientists and explorers trek through the cooling underground, looking for insights into life on this planet—and perhaps on ...

Sometimes, a hole in the ground is just a hole. Other times, it’s a portal to an underground cave spanning miles in width and length. You don’t really know what’s inside unless you dive into the void.

Hidden lava tunnels on the Moon and Mars could one day shelter human explorers, offering natural protection from radiation and space debris. A European research team has unveiled a bold new mission ...

Earth and Mars have many volcanoes on their surfaces. They also have subsurface lava tubes, formed by magma moving underground. And Venus has numerous volcanoes, which might still be active. So does ...

Crawl through Hawaii Island's lava tubes: from lit walks at Nāhuku to raw passages at Kaumana and a guided cavern near ...
