Our @NASAExoplanets mission @NASA_TESS has found its first planet with two suns ☀️☀️, located 1,300 light-years away in the constellation Pictor. A @NASAGoddard intern examined TESS data, first flagged by citizen scientists, to make this discovery: go.nasa.gov/2ZZVtSJ

The final speaker of the #AAS235 @NASA_TESS splinter session is Eliza Kempton. She highlighted how many of the exoplanets being discovered by TESS are prime targets for @NASAWebb - JWST can be used to reveal the properties of the atmospheres of exoplanets!

.@NASA_TESS data pair well with data from and tools used for other missions like the NASA Kepler and K2 missions! Christina Hedges talked about the Kepler/K2/TESS connection at our splinter session at #AAS235.

Did you know @NASA_TESS also studies objects outside of our galaxy? Krista Smith told us all about how TESS does this at #AAS235.

Scientists used @NASAspitzer to confirm the discoveries and to model the potential environments for TOI 700 d. The planets' star is a small, cool M dwarf just over 100 light-years💡⤳ away in the constellation Dorado.

📣Discovery Alert!📣 Meet three new exoplanets discovered by @NASA_TESS. One of the planets, TOI 700 d, is an Earth-sized🌍 world in its star's habitable zone (where liquid water💧 *could* exist on the surface). 👋TOI 700 b, c & d! We see you. go.nasa.gov/2T12IbI

Astronomers using data from NASA’s TESS were surprised to find that Alpha Draconis, a star visible to the naked-eye, undergoes mutual eclipses with its fainter companion star. The brief six-hour eclipses were easy for ground-based observatories to miss. go.nasa.gov/2uhnrxx

Surprise! The bright, naked-eye star known as Alpha Draconis that has been studied for centuries was just discovered to be an eclipsing binary star by @NASA_TESS. Learn more here: nasa.gov/feature/goddard/202… #AAS235

A signal that was originally thought to be from a stellar eclipse in the TOI 1338 system turned out to be from a new world! This planet became TESS’s first circumbinary planet, a world orbiting two stars. go.nasa.gov/36vBpdy

NASA’s TESS discovered its first Earth-size planet in a star’s habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface. @NASAspitzer followed up and confirmed it. go.nasa.gov/2QrTiEv
