Whoa, now that's a #fireball!!! Will there be any new #meteorites for us to study 🙏
Dr Robin George Andrews 🌋☄️@SquigglyVolcano19 May 2024
Hey everyone! Did you see any of the amazing footage of that fireball over Spain and Portugal this morning? Wondering what it was? Here’s a little thread for your Sunday reading.

Geologic map of Wetumpka structure, modified after King et al. (2015). Note that the legend is not in stratigraphic order. Yellow stars show the location of the central polymict breccia outcrops in the apparent crater floor that are the subject of this work. Dashed line shows the approximate extent of the crater rim, and dotted line represents the extra-crater terrain (modified from King et al., 2006). Inset shows the location of Wetumpka crater in Alabama. Neeraja S. Chinchalkar et al., 2024

The lunar dust samples obtained from the Apollo 11 Moon landing site; Grain#1 and Grain#4 are suspected agglutinate particles, while Grain#2 and Grain#3 are likely individual common mineral clasts found on the lunar surface. The samples were extracted from mature mare sample 10084 and encased in epoxy resin to minimize contamination. (Tai-Jan Huang et al., 2024)
