Join us for a discussion with David Armstrong, a researcher at the University of Warwick and Franck Marchis, senior astronomer at the SETI Institute on TOI-489b, the heaviest rocky planet ever observed. Wednesday, Aug 26 at 9am PT. Armstrong, lead author of an article published in Nature, will tell us about the possible origin of TOI-489b which might have been born as a standard hot Jupiter which lost somehow its gaseous envelope. This is a gift for astronomers since this bizarre planet offers them the chance to directly observe the core of a giant planet.
