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

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

#Exoplanets – planets around stars other than the☀️ – were first detected using ground-based telescopes in the 1990s. Many discoveries followed, also thanks to #space telescopes 🛰️👍 #Cheops will follow-up on many of these planets to find out more 🧐 ⬇️➡️esa.int/ESA_Multimedia/Image…

☄️ @UofMaryland scientists found a comet outburst using publicly available @NASA_TESS data. Astronomers captured a clear start-to-finish image sequence of an explosive emission of dust, ice and gases from comet 46P/Wirtanen in late 2018. 💥 nasa.gov/feature/goddard/201…

What happens when a star strays too close to a black hole? Intense tides break it apart into a stream of gas. @NASA_TESS helped produce the most detailed look yet at the beginning of this cataclysmic phenomenon. Visualize how it unfolded: go.nasa.gov/2mYhMsE #BlackHoleWeek⚫

Black holes are mystifying yet awesome cosmic phenomena. Unfortunately, people have many ideas about them that are more science fiction than science fact. Here are five reasons why you wouldn’t want to live near a black hole: go.nasa.gov/2mCZQ6I #BlackHoleWeek⚫
