Hidden Lava Tubes Hint at a Subsurface Network Beneath Venus

Researchers analyzing radar data from the Magellan mission detected what appears to be a large underground lava tube beneath Venus, near the Nux Mons region. The tube is about 1 kilometer wide, with a roof around 150 meters thick and a hollow cavity at least 375 meters high, marking the first confirmed subsurface feature on Venus and supporting long-held ideas about the planet’s volcanic activity. If confirmed, there may be more tubes beneath Venus’ surface, a task for upcoming radar-focused missions VERITAS and EnVision, planned to launch around 2031.

Venus may conceal a giant underground lava tube

Analysis of NASA's Magellan radar data suggests Venus may host a large underground lava tube on Nyx Mons, potentially stretching tens of kilometers. If confirmed, it would be only the second lava tube found on Venus and would support the view that the planet is geologically active; confirming its full size will require higher-resolution radar from future missions like ESA's EnVision with the Subsurface Radar Sounder.

"7000-Year-Old Human Refuge Found in Saudi Arabian Lava Tube"

The Umm Jirsan lava tube system in Saudi Arabia has provided shelter for humans herding livestock for at least 7,000 years, with archaeological remains including stone tool fragments, animal remains, and human bones dating back to that time. This discovery sheds light on the occupation of volcanic caves by early humans as temporary refuges during migrations between oases, and suggests that thousands of similar volcanic caves across Saudi Arabia hold promise for understanding the migrations of early humans.

"7000-Year Human Shelter: Uncovering Ancient Life in a Saudi Arabian Lava Tube"

A nearly mile-long lava tube in Saudi Arabia, known as Umm Jirsan, provided shelter for ancient humans and their domesticated animals for at least 7,000 years. The cave, now inhabited by wolves, foxes, and snakes, contains hundreds of thousands of bones from at least 40 species, dating back to the Neolithic era. While not a permanent residence, the cave served as a crucial pit stop for herders along a pastoral route, offering shade and water for their flocks in the harsh desert environment.

"7000-Year-Old Human Refuge: Prehistoric Occupation in Saudi Arabian Lava Tube"

Archaeologists in Saudi Arabia have discovered evidence that humans were living in a lava tube called Umm Jirsan at least 7,000 years ago, with artifacts such as fragments of cloth, worked wood, rock art of domesticated animals, and human skeletal remains found. The site may have been used as far back as 10,000 years, and it appears to have been a key location for herding routes and hunting activities. The discovery sheds light on ancient human activities in the region and provides insight into their interactions with the environment and local wildlife.
