A team of Italian researchers say they have discovered evidence of a lunar cave and suspect that there could be hundreds more.
Every lunar swirl identified to date coincides with a magnetic field over the lunar surface, which scientists think deflects solar particles. There also seems to be a connection between lunar swirls and lava tubes buried beneath them.
Both the Moon and Mars were volcanically active at one time and the result is lava tubes. A new study shows that lunar and Martian lava tubes might be enormous, and easily large enough to accommodate a base.
