1st lunar lava tube discovered by NASA moon orbiter

For decades, scientists have debated the existence of lava tubes on the moon. A lava tube is a natural tunnel below the surface, formed by flowing lava. If the lava breaks out onto the surface, that creates a cave opening. On July 15, 2024, an international team of researchers, led by the University of Trento in Italy, said it has finally found an ancient lava tube on the moon. It’s the first potential confirmation of a lunar lava tube.
