An artist's illustration of TRAPPIST-1d takes you to the surface of the third planet from the red TRAPPIST-1 star. From here, the star looms larger than our sun and its light casts a red glow across the sky. Look up, and you may catch a glimpse of its six sister planets, as visible as our moon is from Earth. With click or touch, descriptions will appear for each point of interest.
