"Moonquakes Surprisingly Common" is #NASA #astronomy picture of the day (#APOD) - Seismometers left by Apollo crews continued to transmit #quake data for years. Data from max sensor network installation in 1972 until 1977 shows moonquakes are more common than earthquakes. One theory about why says that could be caused by tidal influence from Earth's gravity. Future lunar stations and settlements will need to plan for quakes. apod.nasa.gov/apod/ap250406.ht #planetary #geology

NASA Apollo 11 photo of Buzz Aldrin standing next to the first lunar seismometer, which he and Armstrong had installed NASA APOD image caption https://apod.nasa.gov/apod/ap250406.html 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.

🐚Most likely an Acteonella fossil, estimated to be around 70 million years old. This region was once covered by sea, and one of the nearby mountains was a massive coral reef in ancient times—traces of a long-lost ocean world, now hidden in stone.

Shot with my #nikon d500. More to follow :)

I saw this book on another post - and so went and found a copy at a 2nd hand book shop…
Looking forward to lunches at work with a cup of tea and maybe a couple of rainy Sundays at home…

Mexican Hat rock! I'm still trying to get a really good photo of it. One of these days things will line up with a low angle sun (I seem to always be there mid-day) and a pretty sky. I kind of like how in this shot the 'hat' stands out a bit due to the shadow on the hills in the background. Ooo, I just thought of an idea. I'll try shooting this under a full moon when I'm there later this month.

A color landscape photo of a brown-red sandstone formation that forms a hill in the foreground top with a balanced rock in the shape of a disk. The large hills and cliffs in the background are a tortured landscape of folded sandstone beds of brown-red and greys. The sky is a medium grey color from a heavy overcast.

Mastodon! I'm delivering a talk to a couple of grade 9 classes in a month on the use of space (mainly satellites, but probes to other planets, comets, etc., will be included).

How does your work benefit from satellites?

I'm thinking of a direct use of the data, as opposed to stuff like “internet access” or “my bank relies on satellites to transfer my grant money from one account to another” 😄

Anecdotes, rants, personal stories are all fair game 😊
(To the inevitable suggestion that I just Google this, yes, I can, and have, but I want the human element - I want to be able to say "someone I ‘know’ uses satellites for their job, and this is what they like about the tech”)

Hashtag suggestions are welcome.
(Also - question: Does Mastodon discriminate hashtags with different capitalization? Are #Astronomy and #astronomy functionally different? We *really* need some kind of ISO standard 😉)
