Space scientists confirmed on Monday the existence of a cave on the surface of the moon, suspecting there are hundreds more that could house future astronauts.
According to scientists, the cave is not far from where Neil Armstrong and Buzz Aldrin landed 55 years ago.
An Italian-led team of scientists reported Monday that there is evidence of a large cave accessible from the deepest known crater on the moon, located at the Sea of Tranquility just 250 miles (400 kilometers) from the Apollo 11 landing site.
The crater, like more than 200 others discovered there, was formed by the collapse of a lava tube.
Researchers analyzed radar measurements taken by NASA's Lunar Reconnaissance Orbiter and compared the results with lava tubes on Earth. Their findings appear in the journal Nature Astronomy.
