The Nancy Grace Roman Space Telescope is NASA's next flagship astrophysics observatory, scheduled to launch this September. Combining the sharp vision of the Hubble Space Telescope with a field of view more than one hundred times larger, Roman will enable astronomers to survey the Universe with unprecedented speed and detail. Roman will search for planets beyond our Solar System, map the distribution of dark matter, investigate the mysterious force known as dark energy, and reveal how galaxies have formed and evolved over billions of years of cosmic time. Join us for an introduction to the Roman Space Telescope as we prepare for its launch and explore the exciting discoveries it is expected to make.

About the Series

Stargazing Lectures are free lectures at a public level followed by a Q&A panel and guided stargazing with telescopes (weather permitting). All events are held at the Cahill Center for Astronomy and Astrophysics at Caltech and are free and open to all. No reservations are needed. Lectures are 30 minutes; stargazing and panel Q&A last 60 minutes. Stay only as long as you want.

Stargazing is only possible with clear skies, but the lecture and panel Q&A take place regardless of weather.
