@NASAExoplanets @NASAUniverse I understand the efficiency behind moving multiple accounts into far fewer accounts, I just hope the information you share won't become diluted. Also I appreciate the old accounts pointing us where to go to keep connected to the science. 972 views · 23 likes · 0 reposts · 0 replies Open on X →

@NASA @NASAWebb 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! https://t.co/6B2POkz933 https://t.co/C5chbkDIzj
An artist's concept depicts a giant exoplanet in the path of a red giant  star's destruction.

@NASA @NASAWebb 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! https://t.co/Mt7qSi5ffT https://t.co/fWhprvqB7
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.

@NASA @NASAWebb 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. Another Earth-sized exoplanet later joined the lineup. https://t.co/cSCm4pa0wB https://t.co/

@NASA In addition to finding exoplanets on its own, TESS serves as a pathfinder for @NASAWebb. TESS discovered the rocky world LHS 3844 b, and Webb took a closer look to tell us more about it. Our telescopes, much like our scientists, work together. https://t.co/lC8rqe8xAZ https:
An artist’s concept depicts a dark gray exoplanet very close to its fiery star, of which only the bottom corner appears. The planet’s surface is mottled and partly in shadow. The image is labeled Illustration in the bottom right corner.

@NASA 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. https://t.co/rW4H8Jl0D7 https://t.co/YtCb2uCMpI

#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! https://t.co/V21GAtWwex Here are some of the wondrous worlds.🧵⬇️ https://t.co/927QfAmYLX

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! https://t.co/SurKKApeUX 36.6K views · 165 likes · 61 reposts · 1 replies Open on X →
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… https://t.co/dEmzlcHztk
A vintage style travel poster shows giant flares from a giant, bright young star in oranges, reds and bright yellow burst from the star, affecting a nearby planet. You can see the planet’s atmosphere being blasted away by the energy. It says, Located less than 32 light-years from Earth, AU Microscopii is among the youngest planetary systems ever observed by astronomers, and its star throws vicious temper tantrums! You’ve heard of the “terrible twos”? Well, AU Mic is in the midst of its terrible 22 … millions! This devilish young system holds planet AU Mic b captive inside a looming disk of ghostly dust and ceaselessly torments it with deadly blasts of X-rays and other radiation, thwarting any chance of life… as we know it! Beware! There is no escaping the stellar fury of this system. The monstrous flares of AU Mic will have you begging for eternal darkness.\x3C
Ubicado a menos de 32 años luz de la Tierra, AU Microscopii se encuentra entre los sistemas planetarios más jóvenes jamás observados por los astrónomos, ¡y su estrella tiene unas brutales rabietas! ¿Has oído hablar de los "terribles dos años"? Pues AU Mic está en medio de sus terribles 22… ¡millones de años! Este sistema joven diabólico mantiene cautivo a su planeta, AU Mic b, dentro de un disco de polvo fantasmal y lo atormenta incesantemente con explosiones mortales de rayos X y otras radiaciones, frustrando cualquier posibilidad de vida ... ¡tal como la conocemos! ¡Cuidado! No hay escapatoria a la furia estelar de este sistema. Las llamaradas monstruosas de AU Mic te harán rogar por la oscuridad eterna.

An illustration shows a mottled, rocky exoplanet very close to its orange star with reddish flares against star-filled black space.
