Is the moon shrinking?

The moon may “hit your eye like a big pizza pie” but for how much longer?

Scientists are worried that the moon is shrinking.

New research at the University of Maryland says the moon is shrinking because of quakes caused by “thrust faults” which are stair-shaped cliffs made at the moon’s formation and cooling.

Scientists used seismic data from instruments used in the Apollo missions of the 1960s and 1970s to create an algorithm for the moonquakes which they believe are likely still happening today.

Some scientists hope to one day return with modern seismometers for more research.
