Profs & Pints DC: The Search for Life Beyond Earth
Profs and Pints DC presents: “The Search for Life Beyond Earth,” with Måns Holmberg, postdoctoral researcher at the Space Telescope Science Institute and part of a team of astronomers looking for chemical traces of life on distant exoplanets.
Are we alone in the universe?
While many of us have pondered that question, astronomer Måns Holmberg of Baltimore’s Space Telescope Science Institute is seriously focused on answering it. Last year he was part of a Cambridge-led team of astronomers who generated worldwide headlines by announcing that they had discovered potential evidence of a gas produced almost exclusively by life in the James Webb Space Telescope’s data from the atmosphere of a distant world.
Dr. Holmberg will talk about how the search for life elsewhere is being conducted and what strides are being made on that front. He’ll describe what it would take to confirm signs of life on such a world, what challenges remain, and how the next wave of observations could ultimately tip the scales.
Recent observations from JWST have revealed something extraordinary: the atmosphere of planet K2-18 b contains carbon-based molecules like methane and carbon dioxide and possibly even dimethyl sulfide (DMS), a gas that, on Earth, is almost exclusively produced by life. Dr. Holmberg will discuss what makes DMS a compelling (though not yet definitive) biosignature candidate.
You’ll emerge from the talk with a much richer appreciation of the immense possibilities out there among the stars. (Advance tickets: $13.50 plus sales tax and processing fees. Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)
