Dig deeper at pwnphysics.blogspot.comOn this day in physics: 25 March 1655- Titan, the largest moon of Saturn, was discovered by Christian Huygens. Word of the Day- Lava Tubes- I came across an article in the National Geographic which stated that scientists had discovered Lava Tubes on the moon, and that they are currently being scouted to house a permanent moon base. So Lava Tubes are tunnels under the surface of the Moon, where lava once flowed. Now they are hollowed out caves of drained lava, but proof of volcanic activity on the Moon. Now they can be used to protect our first Moon base from space shrapnel such as asteroids and other hazards like direct exposure to the Sun. Question of the Day: Would you live in a Lava Tube on the moon???Keywords: Lava, Tube, Moon, Lunar, Titan, Huygens
