Galaxies, like our own Milky Way, are among the basic building blocks in our universe. Discovered only one hundred years ago, galaxies are complex systems consisting of billions of stars, along with gas and dark matter. They occupy much of what we see when we point our telescopes up in the night sky. I will discuss what scientists have learned about galaxies both from telescope observations as well as sophisticated computer simulations to better understand how galaxies form and evolve since the birth of our universe.
About the Series
Stargazing Lectures are free lectures at a public level followed by guided stargazing with telescopes (weather permitting). All events are held at the Cahill Center for Astronomy and Astrophysics at Caltech. No reservations are needed. Lectures are 30 minutes; stargazing lasts 90 minutes. Stay only as long as you want.
Stargazing is only possible with clear skies, but the lecture, slideshow, and Q&A takes place regardless of weather.
