NASA’s TESS mission had announced in American Astronomical Society’s 235th meeting, that an exoplanet known as TOI 700 d was found in a multi-planet system, orbiting around TOI 700 star which is part of the Dorado constellation. With the use of Spitzer Space Telescope infrared, astronomers attest their discovery of TOI 700 d, as they also illustrate the planet’s environment to confirm its livability. Planet TOI 700 d gives more excitement to astronomers as they discovered its size is the same as planet Earth’s. Leading astronomers misclassified the star at first, the three planets revolving were thought too close and hot to sustain life, but Alton Spencer, a high school student together with the TESS team, denoted the miscue. The research assistant from Universities Space Research Association, Gabrielle Engelmann-Suissa stated: “Someday, when we have real spectra from TOI 700 d, we can backtrack, match them to the closest simulated spectrum, and then match that to a model, it’s exciting because no matter what we find out about the planet, it’s going to look completely different from what we have here on Earth.”

On the other hand, the TESS or Transiting Exoplanet Survey Satellite, have discovered a planet revolving around two suns just like in Star Wars’ Tatooine. This Tatooine planet known as TOI 1338 b is part of the Pictor constellation, with a size between Neptune and Saturn, and with constant eclipses coming from its two stars. An intern at NASA’s Goddard Space Flight Center, Wolf Cukier, noticed this Tatooine in TESS data and said: “I was looking through the data for everything the volunteers had flagged as an eclipsing binary, a system where two stars circle around each other and from our view eclipse each other every orbit. About three days into my internship, I saw a signal from a system called TOI 1338. At first, I thought it was a stellar eclipse, but the timing was wrong. It turned out to be a planet.”
