The Moon is Shrinking! Brace for "Moonquakes"

Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! In this video, we unravel the mysteries of the Moon's dynamic nature. Why the Moon is shrinking? and by how much? How does this relate to moonquakes? how often do moonquakes occur and how strong are they? Let's talk about the latest research and discoveries about the Moon's geology. Learn about the different types of moonquakes, from shallow quakes caused by tidal stresses to deep-seated tremors originating from the Moon's interior, and how these seismic events offer clues about the Moon's internal structure and what it means for astronauts and future moon missions.
