Speaker: Shane L. Larson (Northwestern University)

Nearly everything we know about the universe has been discovered using photons - light in all its myriad forms. However, using advanced technology we can now access the cosmos through the detection of ripples in the fabric of spacetime itself: gravitational waves. 

Dr. Larson will explore the modern description of gravity, how we can measure gravitational waves, and what we expect to learn. He will focus on LISA, the space gravitational wave observatory being launched in the early 2030s by ESA and NASA. LISA observations will unveil the adventures of black holes of all sizes, neutron stars, and white dwarfs as they interact, merge, and send ripples across the universe. Join us to explore these discoveries - because gravity has quite a story to tell.

The STScI Public Lecture Series offers talks on a diverse selection of cosmic topics, typically held the first Tuesday of every month. The 2024 Public Lecture Series is continuing an online-only format. This lecture will be presented with a livestream to YouTube, and questions can be asked in the YouTube chat. As usual, the recording will also be posted on our YouTube channel. We will, as necessary, adjust from the traditional first Tuesday at 8 PM schedule to accommodate our speakers.
