But a high school searching through data gathered by TESS contributed to its latest discovery.
The planet orbiting two suns, like Tatooine in the Star Wars films, is the first of its kind for the TESS mission.
The planet TOI 1338 b was found 1,300 light-years away in the Pictor constellation. It's the only planet in the system with two stars. It's between the sizes of Neptune and Saturn and experiences regular eclipses from its stars.
The stars whirl around each other in orbit every 15 days, with one 10% more massive than our sun and the other is more diminuitive and cooler.
