Public Star Night 21 February 2020 – Dr Emily Hardegree-Ullman – Erased from History

Our guest speaker for this public star night will be Dr. Emily Hardegree-Ullman.  The title of her presentation is “Erased from History”.

Einstein, Hawking, Hubble. Ask a stranger to name a famous astronomers and 9 times out of 10 they will think of a man. Despite the incredible contributions of women to astronomy, their names are all but forgotten. In this talk, Dr Hardegree-Ullman will highlight some of the significant achievements you might not have heard about. The women who this talk will be about are the Harvard Computers (Annie Jump Cannon, Henrietta Swan Leavitt, and Antonia Maury) and Cecelia Payne-Gaposchkin, Jocelyn Bell Burnell and Margaret Hamilton and Katie Bouman, as well as Vera Rubin, who discovered dark matter.

Dr. Emily Hardegree-Ullman is a professor in the Physics Department at Colorado State University. She earned her PhD from Rensselaer Polytechnic Institute where she studied the chemical composition of young stellar systems. Emily discovered the fascinating subject of astrobiology while an undergraduate at the University of Arizona. Her prior research projects include searching for methane lakes on Titan, investigating the evolution of protoplanetary disks, and observing extrasolar planet transits.

Weather permitting after the presentation, visitors will be invited to look through our large telescope at various celestial objects. Our Public Star Nights are usually held the third Friday of each month, except July, when we are closed for annual maintenance.
