One of the most important realisations that planetary scientists have come to in the last 30 years is that in the search for potential habitability in our solar system, the focus need not only be on planets close to the Sun, where water on the surface is in liquid form. Based on observations from instruments on the GALILEO spacecraft at Jupiter and the CASSINI spacecraft at Saturn, there are many potential places in our solar system where liquid water oceans may exist below the surface. In this Discourse, Michele Dougherty, the first female Astronomer Royal, will describe the discoveries made by CASSINI scientists, as well as exploring the future discoveries waiting to be made at Jupiter’s moons with the European Space Agency mission JUICE. The JUICE mission was successfully launched from Kourou in French Guiana in April 2023, and the spacecraft will spend at least three years making detailed observations of the giant planet Jupiter and three of its largest moons, Ganymede, Callisto and Europa, which all show hints of hosting liquid water oceans beneath their crusts. On Earth, life thrives in the deepest, darkest parts of our oceans near hydrothermal vents. Ultimately leading to the big question: could life similarly evolve or survive in the ocean floors of these moons? By booking to attend events at the Royal Institution, you confirm that you have read and agree to the Ri's event terms and conditions. Discourses are one of the Ri’s oldest and most prestigious series of talks. Since 1825, audiences in the theatre have witnessed countless mind-expanding moments, including the first public liquefaction of air by James Dewar, the announcement of the electron by JJ Thomson and over 100 lectures by Michael Faraday. In more recent times, we have had Nobel laureates, Fields medal winners, scientists, authors and artists – all from the cutting-edge of their field. Discourses are an opportunity for the best and brightest to share their work with the world. Steeped in nearly two centuries of tradition, a Discourse is more than just a lecture. To keep the focus on the topic, presenters begin sharply at 7:30pm without introduction and we lock the speaker into a room ten minutes ahead of the start (legend has it that a speaker once tried to escape!). Some of our guests dress smartly for our Discourse events to add to this sense of occasion. Discourses are free for Ri Members and Patrons - consider joining today. Find out more about the history of Discourses on our blog. The doors will open at approximately 6.45pm, and all ticket holders must take their seats by 7.20pm for a prompt start at 7.30pm. There will be a brief question/answer period after the talk. Latecomers will be admitted to the gallery. Event image by NASA
