By contrast, lava caves, widely known as lava tubes, are formed in a geological instant—a year or two, sometimes weeks—by an eruption from the Earth’s crust.

Mathew Stewart at Griffith University in Brisbane, Australia, and his colleagues excavated a trench inside Umm Jirsan. At 1.5 kilometres in length, it is the biggest lava tube in Saudi Arabia. The ...

Inside lava tubes on Earth, scientists have found microbial life appearing like a sparkly, yellowish film on the walls. This microbial life, Osburn said, can live off carbon dioxide.

The lava within active lava tubes in Hawai’i, for example, is around 2200° F (or 1250° C). People are therefore only allowed inside lava tubes that are completely drained and cooled.

ANCIENT humans lived in lava tubes inside cave systems around 7,000 years ago, according to a new study. The lava tube in question is called Umm Jirsan and is located in Saudi Arabia. A new study a… ...

The idea is to build a base inside a lunar lava tube, where astronauts gain additional protection from the thick rock ceiling overhead. China is considering the idea now, just like others before them.

Once inside the pit or lava tube, building a structure would be no more difficult than building on the Moon’s surface. In fact, it may even be easier due to the favorable temperature conditions.

Inside a lava tube opening registering about 140°F, Fernández and fellow cave specialists David Sanz Mangas and Eduardo Díaz Martín collect samples for testing lava composition.

A similar inflatable habitat architecture could be used inside lunar lava tubes. Studies have investigating sealing off and pressurizing a lava tube itself for use as a lunar habitat, but that ...

Inside ancient Saudi Arabian lava tube that humans hid in 7,000 years ago Artefacts, rock art, and skeletal remains are but a few of the amazing materials archaeologists discovered inside the ...
