The lava is gushing from a tube that was exposed when a huge, 26-acre lava delta collapsed into the ocean at the site on New Year’s Eve. The collapse of the newly formed land triggered massive ...

Lunar lava tubes offer shelter from harsh surface conditions. Evidence suggests at least one large underground lava tube exists. These tubes could protect astronauts from radiation and extreme ...

Lunar lava tubes seem to be still larger, the researchers found, with collapse sites 300 to 700 times the size of Earth's. Lunar lava tubes likely range from 1,600 to 3,000 feet (500 to 900 m).

On the surface of the Moon, there are more than 200 known pits that scientists have speculated are underground cave conduits.

Hawaii’s Kīlauea volcano began erupting again on Wednesday for the 30th time in under a year, continuing to be among one of ...

Scientists have discovered lava tubes just under the surface of the Moon. The team used radar to answer a question scientists have been asking for over 50 years. If we’re lucky, these tubes ...

This is when the sun pours through a hole in the roof of the Mojave Desert Lava Tube, creating a magical beam of light onto the dusty floor. The pictures you see here were taken around 2 pm in June.

Lava tubes are tunnels that form from lava flowing during long volcanic eruptions. As the lava flows, the top and sides of the stream harden, forming a tube in which the rest of the lava continues ...

Lava tubes can also form when the surface of a lava stream hardens into rock, while the inner stream of lava continues to flow, according to Oregon State University ‘s volcano education page.

Given their proximity to the surface, lava tubes actually tend to have more entrances than in other types of caves. As a result, there are a whole bunch of places across the world where you can go ...
