NASA Observes Moon's Tidal Bulge from Lunar Orbit

The moon’s gravity is responsible for the rise and fall of the ocean’s tides, but the Earth has a similar effect on the moon.   Scientists at the U.S. space agency, NASA, say they’ve been able to observe, for the first time from lunar orbit, a “bulge” in the moon caused by the “gravitational tug-of-war with Earth.” “The deformation of the moon due to Earth’s pull is very challenging to measure, but learning more about it gives us clues about the interior of the moon,” said Erwan...
