For the past six years, our TESS mission has been staring at the sky for long periods, hunting for possible planets outside our solar system. Since TESS catches changes in its view, it can also help us find and study other dynamic sources — here are a few of our favorites! 🧵

#OTD in 2018, @NASA launched the Transiting Exoplanet Survey Satellite to search for new worlds. So far, it’s discovered 432 planets and 7,138 planet candidates! go.nasa.gov/3vXUCq8 Here are some of the wondrous worlds.🧵⬇️

ALT An animated cartoon short shows the TESS spacecraft lifting its solar panels like wings, and in a fabulous poof, the light brightens and colorful exoplanets appear.

A super-Earth in the habitable zone! TOI-715 b orbits a small, reddish star that is, by astronomical standards, fairly close – only 137 light-years away. The same system also might harbor a second, Earth-sized planet! go.nasa.gov/3Q3qpN5
An artist’s concept shows one way that planet TOI-715 b, a super-Earth in the habitable zone around its star, might appear to a nearby observer. On the right lower foreground, this illustration shows a 'super-Earth' – a planet larger than Earth but smaller than Neptune – with a brownish atmosphere flecked with white, horizontal strips of cloud. The planet's left side is partially lit by its reddish parent star, a red dwarf, smaller and cooler than our Sun, seen in the upper left of the image. It is labeled Artist’s concept in the bottom right corner.

Exoplanet 8 Ursae Minoris is somehow orbiting a star that should have destroyed it. TESS studied a star in the latter stages of becoming a red giant – and discovered a planet in a stable orbit! go.nasa.gov/4cV0t02

April is #CitSciMonth and there are lots of ways to join in. Of course, we're partial to the programs where you can discover worlds, but you do you and @DoNASAScience! go.nasa.gov/3TX4pox

Citizen Science Projects - NASA Science

Through the projects below, sometimes called "citizen science" or "participatory science" projects, volunteers and amateurs have helped make thousands of important scientific discoveries.

Of 5,609 confirmed exoplanets, just 200 are thought to be terrestrial – rocky worlds like Earth and Mars. Fewer still are in their stars' habitable zones. That doesn't mean they're inhabited, of course, but we're looking! go.nasa.gov/3Ul23RP
An artist's concept depicts the imagined view from the surface of a terrestrial exoplanet. The surface is rocky with hills or mountains on the horizon. The shy is dusky with one large star low on the horizon, with two other stars in sky, higher and farther away. It is labeled Illustration and the credit is ESO.

In a cosmic ballroom 1,900 light-years away, six stars are dancing in pairs across space. All three pairs are entwined, and all six stars go through eclipses to our view. go.nasa.gov/3TZloX4
Eclipsing binary schematic headlined Structure of Sextuple System TYC 7037-89-1. This schematic shows the configuration. The inner quadruple is composed of two binaries, A and C, which orbit each other every four years or so. An outer binary, B, orbits the quadruple roughly every 2,000 years. All three pairs are eclipsing binaries. The orbits shown are not to scale. Credit: NASA's Goddard Space Flight Center

Pretty in purple 💜 Nearly 200,000 light-years from Earth, the Large Magellanic Cloud circles the Milky Way in a long and slow dance around our galaxy. Vast clouds of gas slowly collapse to form new stars. go.nasa.gov/4cVt59F
The Large magellanic cloud shines in purple with black streaks in this image from @NASAHubble. The gas and dust is purple and new stars shine in white and blue.

It's an honor just to be nominated (but...vote for us 😉) NASA is up for 13 #Webbys, including social media and broadcast coverage of two planetary missions - #OSIRISREx and @EuropaClipper! Here's how to vote for your favorite NASA internet moments: nasa.gov/general/nasa-receiv…
An engineer attends to the OSIRIS-REx sample return capsule soon after its landing in the Utah desert. The capsule is about the size of a large truck tire, charred black from reentry, and rests on flat, bare, salty soil with a few scrub plants nearby.

A super-Earth in the habitable zone 1,400 light-years away, Earth has a bigger, older cousin. Kepler-452 b orbits a Sun-like star in 385 days and has a temperature similar to Earth's. go.nasa.gov/4aPYzvN

ALT This artist’s concept depicts one possible appearance of the planet Kepler-452b, the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. The habitable zone is a region around a star where temperatures are right for water — an essential ingredient for life as we know it — to pool on the surface. Scientists do not know if Kepler-452b can support life or not.
