Penn Science Café: “Watching the Hidden Evolution of Galaxies”
Tuesday, Aug. 15, 6-7 p.m.
World Cafe Live Upstairs, 3025 Walnut St., Philadelphia
The galaxies seen in the universe today are the result of a long process of formation and evolution. By using the finite speed of light, one can view galaxies as they were in the past, and the very expansion of the universe provides a way to measure the distance to them, together providing 3-D snapshots of galaxies changing over time. The most detailed and comprehensive picture of the universe comes from visible light, but much of the story of galaxy formation is only available by looking at infrared and radio wavelengths. Dr. Aguirre will discuss his work on new instruments to view this heretofore invisible process and how it is linked to the larger evolution of the universe.
The talk is part of the Penn Science Café free public-lecture series presented by Penn Arts & Sciences and the Office of University Communications that takes science out of the lab for a night on the town. Dr. Aguirre’s presentation will be followed by an audience Q&A. Café events are free and open to the public. Food and beverages will be available for purchase. Seating is limited. RSVPs are encouraged. To RSVP or for more information or directions: Gina Bryan at 215-898-8721 or firstname.lastname@example.org.
