Moonquakes Surprisingly Common

https://apod.nasa.gov/apod/image/2504/AldrinSeismometer_Apollo11_960.jpg

Why are there so many moonquakes? Analyses of seismometers left on the moon during the Apollo moon landings reveal a surprising number of moonquakes occurring within 100 kilometers of the surface. In fact, 62 moonquakes were detected in data recorded between 1972 and 1977. Many of these moonquakes are not only strong enough to move furniture in a lunar apartment, but the stiff rock of the moon continues to vibrate for many minutes, significantly longer than the softer rock earthquakes on Earth. The cause of the moonquakes remains unknown, but a leading hypothesis include tidal gravity from -- and relative heating by -- our Earth. Regardless of the source, future moon dwellings need to be built to withstand the frequent shakings. Pictured here, Apollo 11 astronaut Buzz Aldrin stands beside a recently deployed lunar seismometer, looking back toward the lunar landing module. Explore Your Universe: Random APOD Generator

More on what #Perseverance has been spending its time on these last few sols. Those spots are measured in μm rather than in mm.

Located in the southern constellation Puppis, the area around NGC 2467 is a bustling star-forming region. This vibrant cluster, only a few million years old, is a stellar nursery where stars continually form from dense dust and gas clouds.

Mind-Blowing Scale: Betelgeuse Compared to Our Solar System! 🤯☀️

Imagine replacing our Sun with the colossal red supergiant star, Betelgeuse! Its size is absolutely staggering—it would extend beyond the orbit of Jupiter, swallowing Mercury, Venus, Earth, Mars, and a chunk of the asteroid belt! 😱

And the cosmic drama doesn't end there!
