Scientists at the University of Trento have unveiled the first direct evidence of extensive underground caverns beneath Venus’s surface, lending credence to long-held theories about the planet’s volcanic past. This groundbreaking study reveals a colossal tunnel nearly 1 kilometer wide with an estimated roof thickness of 490 feet and internal height exceeding 375 meters.
Despite its dense atmosphere and extreme heat, this discovery validates previous speculations that Venus contains hidden underground structures. Previously obscured by Venus’ inhospitable conditions, these new findings underscore the planet’s geological complexity, suggesting a vast network of tunnels beneath its crust. This revelation is poised to revolutionize our understanding of Venus and paves the way for future exploration missions.
NASA’s VERITAS and the European Space Agency’s Envisat are scheduled to launch in 2031. These ambitious undertakings aim to map these ancient volcanic caverns, allowing scientists to probe the depths of Venus’ hidden underworld. The insights gleaned from these missions will not only shed light on Venus’ geological history but also provide critical data for future space exploration endeavors.
The existence of such substantial tunnels suggests that Venus harbors a rich and complex geological landscape, potentially revealing new information about volcanic activity and environmental changes over time. This discovery marks a significant step forward in our understanding of one of the least explored planets within our solar system.
