This week The Observatories will host astronomers from around the globe for the inaugural Carnegie Symposium in Honor of Leonard Searle. The topic of the meeting is "Understanding Nebular Emission in High-Redshift Galaxies: Massive Stars, Chemical Abundances and Photoionization Models."
With the New Horizons historic flyby of Pluto next week, imagine how excited we were a few weeks ago to unearth a set of plates from 1925 in our vault that include Pluto--five years before Pluto was discovered. This unexpected find led to a bit of historical detective work to uncover the story of these unusual astronomical plates. The short video tells the tale of our digging, and what we learned from it, and highlights the amazing work done by astronomers of an earlier, pre-digital era. You never know what you might find in your own archives!
