With over 7,000 exoplanets identified in our galaxy, scientists are shifting their focus to studying these worlds' characteristics in the quest for extraterrestrial life. The backdrop for one team is the discovery of super-Earth HD 20794 d, an exoplanet detected by researchers from the University of Geneva (UNIGE) and NCCR PlanetS. Orbiting in an eccentric path, HD 20794 d moves in and out of its star’s habitable zone, making it a compelling subject for further study. This breakthrough, built on two decades of observations with the world’s most advanced telescopes, has just been published in Astronomy & Astrophysics.
Join planetary astronomer Franck Marchis and lead author Nicola Nari for a discussion on the search for exoplanets, what a habitable world could look like, and how HD 20794 d will help us understand our universe.

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.
