Imagining Exoplanets: Visualizing Faraway Worlds Using Global Climate Models

Authors Info & Claims
Published:20 August 2020Publication History

ABSTRACT

In the past decade, we’ve discovered over 4,000 exoplanets1, or faraway worlds orbiting other stars. However, we can’t yet take a clear picture of any of them, so how can we begin to imagine what they look like?

Three teams at NASA’s Goddard Space Flight Center developed a unique approach to tackling this problem for an exoplanet called TOI-700 d. By combining 3D climate models, a newly-developed module for an exoplanet visualization tool, and Adobe After Effects, they successfully visualized possible scenarios for the planet (Figure 1) and offer an effective model for approaching future discoveries.
