(TIME) — The moon is shrinking, and it's causing powerful “moonquakes” mag.time.com/0qv11wG.
A new NASA sponsored study found that as moon's interior cools, it shrinks, which causes its hard surface to crack and form fault lines
As the moon’s interior cools, it shrinks, which causes its hard surface to crack and form fault lines, according to research sponsored by NASA. The moon has gotten about 150 feet skinnier over the last few hundred million years.
Astronauts have placed seismometers on the moon over a series of past missions. Scientists, who determined that the moonquakes are close enough to the fault lines to establish causality, published their analysis in a study in Nature Geoscience on Monday, according to NASA.
