The Institute for Research on Exoplanets invite you to the public lecture:

Titan : 
Ingredients for Life

by Sarah Hörst, assistant professor at Johns Hopkins University. Prof. Hörst is an expert on the formation and composition of planetary atmospheric hazes. She received her Ph.D. in 2011 from the University of Arizona where she studied the chemical processes in Titan’s atmosphere.

The conference will take place on Wednesday, October 16, 2019 at 7:30 pm, at the campus MIL of University of Montreal,  room A-4502.1.

No prior knowledge is necessary. iREx conferences are for anyone who wants to learn about exoplanets and astronomy, regardless of age or scientific knowledge.

Saturn’s largest moon, Titan, is unique in our solar system. Below Titan’s thick organic haze layer, rivers of methane carve channels into an icy bedrock and flow into large hydrocarbons seas. Across the landscape, water ice mountains and extensive organic sand dune fields are simultaneously alien and reminiscent of Earth. Titan’s lake mottled surface and thick, organic rich atmosphere may be an ideal setting for life as we do not know it and there is certainly much yet to be learned about our own home from the study of Titan. NASA’s newly selected mission Dragonfly will use a rotocraft lander to explore multiple settings on Titan and answer many of our outstanding questions.


To Get There

The Université de Montréal’s campus MIL is located at 1375 Avenue Thérèse-Lavoie-Roux, Montréal, QC H2V 0B3. It is easily accessible via the Acadie métro station. When you exit the métro, follow the overpass that goes over the train rails. Afterwards, head towards the building on the right-hand side. Directions to the room will then be clearly visible.
