Watcher of the Sky: An Observational Astronomer's View of the Universe
Wall Scholars Cafe
25 Mar 2009
Talk by Harvey Richer, Physics & Astronomy and 2009 Distinguished Scholar in Residence
Observational astronomy is the science of observing the Universe using various astronomical instruments. In this talk I will discuss some of the objects, events and instruments that have influenced me in my career as an observational astronomer. I will present a few incidents from early in my career and then discuss a number of celestial objects that have shaped my own research over the years. In particular I will mention recent work with the Hubble Space Telescope which has allowed me to discover the oldest known planet in the Universe, derive ages for the most ancient star clusters known and play "MythBuster" with a very fashionable current paradigm in star cluster physics.
Dinner and talk 6:30 to 9:00 pm, but welcome at 6:00 pm reception.
