What is an exoplanet?
April 22, 2021 at 12:07 pm
Exoplanets are planets orbiting distant stars beyond our Solar System, and today astronomers calculate that for every star we can see in the night sky, there is on average at least one exoplanet in orbit around it.

The concept of exoplanets is hardly new: as far back as 1584, Italian philosopher Giordano Bruno suggested space was filled by “an infinity of worlds of the same kind as our own”. An illustration depicting the variety of exoplanets discovered so far. Credit: NASA/JPL-Caltech/Lizbeth B. De La Torre
Over the past century, numerous authors, TV directors and film producers set their stories on planets beyond our own Solar System.
As a young girl growing up in small-town Vermont, Aki Roberge dreamed of other worlds.
An avid science fiction fan, she wondered if the kinds of planets she saw in the âStar Warsâ movies, with their varied climates and cultures, creatures and civilizations, might really exist.
Today, and for more than a decade now, she actually explores such possibilities, searching not for parched Tatooine or ice-clad Hoth, but for real exoplanets â planets orbiting other stars.
Dr. Aki Roberge, a research scientist in NASAâs Exoplanet and Stellar Astrophysics Lab at the Goddard Space Flight Center in Maryland, right outside Washington, D.C., will talk about her life, her work and the latest breakthroughs in this relatively new branch of astronomy at 7 p.m. Friday. Itâs part of Wyoming Stargazingâs âThe World Above the Tetonsâ speaker series.
