"Pictures of Distant Worlds"
Dr. Bruce Macintosh (University of California Observatories)
Mar. 11, 2026
In the past three decades, more than 6000 planets have been discovered orbiting other stars. Advances in technology have allowed a handful of giant planets around other stars to be imaged directly. Dr. Macintosh tells us about the first-ever images of other solar systems — and the technology that has allowed us to discover them, such as the Gemini Planet Imager — as well as the future planet-hunting space telescopes. The ultimate goal is detection of a second ‘pale blue dot’ — an Earth twin where we could even see the biosignatures of extrasolar life. (He also talks a bit about the wind damage to the Lick Observatory and what is being done to repair the historic dome.)
Bruce Macintosh is the Director of the University of California Observatories in California and Hawaii. He co-led the team that imaged the first extrasolar planets, and was the Principal Investigator of the Gemini Planet Imager, an advanced planet-finder for the Gemini South telescope.
