 All right, Dan, time for a quick look at what's trending. If you can't afford rent on Earth, there might be a cave on the moon you could stay in. I'll take it. Researchers announced today that they found the deepest cave on the moon. They think it could be 500 meters deep and has a skylight entrance that's 330 meters across. Experts are considering using a hopping robot called the Lunar Leaper to find out what's inside.
