Happy Space Science Saturday! Planning some observing? Remember to check our AllSky Cam to view weather conditions at the observatory! You might even get a cool shot like a view of the moon over the domes (seen in this image)

Plate #tectonics represents a defining framework of modern #geoscience, accounting for large-scale features on Earth’s surface, such as mountains and valleys, as well as the processes that shape them, like volcanoes and earthquakes.

Present-day plate tectonics have not been observed on any other world in the solar system, and evidence of past activity on planets such as #Mars and #Venus is circumstantial.

Perhaps the best case for extraterrestrial plate tectonics is found in the floating ice shell of #Jupiter’s #moon #Europa.

The plate tectonics on Europa differs from its Earthly analog. It is spatially widespread; it is regionally confined rather than globally connected; it occurs intermittently and is not happening now; and during past activity, plates drifted limited distances of between 10 and 100 kilometers.

Europa’s Plate Tectonic Activity Is Unlike Earth’s

The moon of Jupiter has likely experienced intermittent, regional plate tectonic activity in the past, although the plates are currently dormant.

A weather application I use says the moonrise time from this morning but for moonset, there's no time like the Moon is going to never set and will always be visibly present.
