The first detection of an extrasolar planet took place 25 years ago. We now know of more than 4000 planets orbiting distant suns. Some of these exoplanets are similar to planets in our own solar system, while other have no solar system analogue. Among the most interesting planets are those that can harbor life as we know it – habitable planets. In the lecture, we will discuss the methods and instruments needed to detect terrestrial planets similar to our own planet Earth, and what are the signatures we look for to determine a planet habitability.

A native of Tel Aviv, Dr. Sagi Ben-Ami graduated in physics from the Technion and completed his PhD in the Department of Particle Physics and Astrophysics at the Weizmann Institute of Science. Dr. Ben-Ami was awarded a NASA Einstein fellowship in 2014 and conducted his postdoctoral research at the Harvard-Smithsonian Center for Astrophysics. In January 2020, he returned to the Department of Particle Physics and Astrophysics where he joined the Weizmann team on the Israel-U.S. space-borne ULTRASAT mission, the latest revolutionary project in space exploration. An experimental astrophysicist, Dr. Ben-Ami develops advanced instruments and methods that help detect “bio-signatures”—substances whose origin specifically requires a biological agent—on planets outside of our solar system. Dr. Ben-Ami is currently working on developing a spectrograph, an instrument whose ability to capture extremely high spectral resolutions will enable the detection of O2—one of the strongest indicators of planetary life.
