The first picture of the Earth from space was made #onthisday in 1966. It's so inspiring and humbling that we chose to use it to decorate the entry way in the Seeley G. Mudd building (home to a number of Caltech's Division of Geological and Planetary Sciences scientists) so we could see it every day!

Happy #Aviation Week! #FunFact: Caltech GALCIT’s 10-foot wind tunnel - in operation from 1929 to 1997 - tested most of the warplanes that helped the Allies win World War II. ✈️

Engineers from Caltech have generated a computer simulation of underwater bubble rings that is so realistic it is virtually indistinguishable from a video of the real thing. Its developers hope that the simulation can shed light on the mathematics and forces that govern such phenomena. • See the full video and learn more about the research - just search “bubble rings” on Caltech.edu.
😍😍😍 • @ziiiiyawn is giving us life with this illustration of Beckmann Institute at sunset! • The image was featured on the cover of the 2019 issue of Totem, Caltech’s annual literary and visual arts magazine.
