#OTD in 2018, @nasa launched the TESS Space Telescope. In its first five years, TESS has discovered 329 planets and 4,300+ planet candidates. go.nasa.gov/3opfR05 Here are some exoplanet highlights!🧵⬇️
#NASAExoplanets


TESS’ first discovery was a world called Pi Mensae c. It orbits the star Pi Mensae, ~60 light-years away and visible to the unaided eye in the Southern Hemisphere. This discovery kicked off NASA's new era of planet hunting. go.nasa.gov/2VFm70W

Hello, cosmic caterpillar!

This #HubbleClassic image shows a light-year-long knot of gas and dust. Its long shape is the result of ultraviolet radiation blasting from bright stars!

On Friday, April 21, @northropgrumman's uncrewed Cygnus spacecraft will depart the space station to begin a planned destructive re-entry and safely burn up in Earth’s atmosphere. Live coverage begins at 7am ET on @nasa TV, with departure at 7:20am. go.nasa.gov/3NbEaJl

Happy birthday, TESS! 🥳

We’re excited to keep working together with you to further exoplanet science 🪐

NASA astronaut Steve Bowen and UAE astronaut @Astro_Alneyadi will step outside the @Space_Station on Friday, April 28, to prepare for new solar arrays that will boost the station's power capacity.

Tune in Monday, April 24, for a live spacewalk preview: go.nasa.gov/3KJ8isB

In 2020, TESS discovered its first Earth-size world in the habitable zone of its star – the distance from a star at which liquid water *could* exist on a planet’s surface. Earlier this year, a second rocky planet was discovered in the system.
#NASAExoplanets


In addition to finding exoplanets on its own, TESS serves as a pathfinder for @NASAWebb. TESS discovered the rocky world LHS 3448 b, but Webb will tell us more about it. Our telescopes, much like our scientists, work together. go.nasa.gov/3L5mEW2
#NASAExoplanets


TESS looks at stars to find much tinier planets orbiting them. A closer look at a neighboring star required scientists to peer through the dusty realm of creation. Within the debris disk of an angry young star, they found a planet! And then another…

Five years ago today, NASA's Transiting Exoplanet Survey Satellite (TESS) mission was launched in search of planets outside our solar system, and boy did it succeed. Happy launchiversary TESS!

If aliens from there visited us they would be astonished at how blue everything is


Shining brighter than a trillion suns✨
Our galaxy, seen from a distance, would appear as bright as 10 billion suns. @NASAWebb observed an object brighter than one *trillion* suns. It's actually two galaxies merging, leading to luminous star formation. go.nasa.gov/3oef1TD

Earth at night. 🌏🖤

Dark skies help us see the brilliant color of auroras, pinpoint constellations and other planets in the night sky, and are important for the health of plants, insects, animals, and humans. #DarkSkyWeek
#NASAEarth



Auroras are caused by particles from the Sun interacting with Earth’s magnetic field and upper atmosphere. The northern and southern lights are more difficult to observe near the lights of cities and large metropolitan areas.
#NASAEarth


Scientists compared nighttime lights seen by NASA satellites and @cdc health data.

They found that poorer, non-white neighborhoods experience more artificial light at night, which can disrupt circadian rhythms and cause sleep deficiency. #DarkSkyWeek

Heavy rains overtopped the banks of the Shabelle and Juba rivers, affecting hundreds of thousands of people in Ethiopia and Somalia. NASA’s Terra satellite captured flooding in this enhanced-color image which makes the water, in dark blue, stand out.

Shine bright like a ULIRG 💎

With the light of a trillion suns, an ultra-luminous infrared galaxy (ULIRG) shines in the latest @NASAWebb image. Located 250 million light-years away, this target is actually the result of two colliding spiral galaxies: go.nasa.gov/3L7dojN

Crew would, I hope, have been called “donauts”?

I think I would get tired living in something like that.

The exhausted Apollo 13 flight controllers, joined by astronauts, managers, and VIPs in the Mission Control Center in Houston, rejoiced in the safe splashdown of the Apollo 13 astronauts in the Pacific Ocean #OTD in 1970. go.nasa.gov/3UpaJVF

One of my favorite movie memories is watching Ron Howard's "Apollo 13" at the Chinese Theater and a Q&A with Jim Lovell afterwards.


hey girl, are you an ULIRG? because you shine brighter than a trillion suns ✨

Arp 220 is an ultra-luminous infrared galaxy (ULIRG) that emits 300 times more light than the Milky Way. It also happens to glow brightest in infrared light, Webb's specialty: go.nasa.gov/3oef1TD

very interesting. On the subject of circadian rhythms, it would make sense to reduce the colour temperature of domestic led lights
