Meet Our Hosts
Franck Marchis is a senior planetary astronomer at the SETI Institute and Chief Scientific Officer and Founder at Unistellar. He has dedicated his work to the study of our solar system, specifically the search for asteroids with moons, using mainly ground-based telescopes equipped with adaptive optics.
Simon Steel is Deputy Director of the Carl Sagan Center for Research at the SETI Institute. As an observational astrophysicist, he specialized in optical spectrophotometry, with an interest in the star formation histories of galaxies.
Bettina Forget is an art-science researcher, educator, and visual artist who joined the SETI Artist-in-Residence program in 2016 as a Researcher in Residence and became its Director in 2020. In this capacity, she facilitates collaboration between artists and the SETI Institute’s scientists, promotes art-science research, and weaves a network of institutional partners active in art, science, and technology.
How Clouds Hide Alien Worlds—and How Astronomers See Through Them
The James Webb Space Telescope is transforming our understanding of exoplanets—but what happens when clouds get in the way? Astronomers have developed a new method for detecting clouds and hazes in distant planetary atmospheres, helping researchers determine when they're seeing a planet itself and when weather is obscuring the view.
Join SETI Live as host Dr. Lauren Sgro welcomes lead author Dr. Sagnick Mukherjee to discuss this innovative method, how it works, and what it means for the future of exoplanet science and the search for life beyond Earth.

SETI Institute
Scientists are getting closer in their search for life beyond earth. But with limited federal funding for the search for extraterrestrial intelligence, supporters are the reason cutting-edge scientists can keep their eyes on the sky.
