ARCHIVED NASA Exoplanetsさんのイラストまとめ

This sweet star (20 times more massive than the Sun) was blasted away from its stellar companion a million+ years ago. @chandraxray is studying the resulting shock wave near Zeta Ophiuchi. Planets can also be ejected from systems – we call them rogues. https://t.co/SThyNdLcrg

Where the grass is always redder on the other side...
A faraway world orbiting a red star inspired us to think differently. What might plants on such a planet look like? Would they be black or violet, or, perhaps, red? Take our guided tour: https://t.co/svp6QnrMMC

64 light-years away, astronomers found and measured 30 comets with @NASA's TESS space telescope. It's the first time the size distribution of comets has been measured in a planetary system other than our own. https://t.co/OyPjG9ARyA

If you could stand on one of the seven rocky planets of TRAPPIST-1, the other worlds are so close that they would hang in the sky like giant moons.
Can you imagine?
We can.

Someone ''space-ial'' in your life? Let them know with a card from @NASA 💌
Happy #ValentinesDay! https://t.co/QZGCyALTP5

Science is all about teamwork. Our TESS spacecraft🛰️ is not only finding exoplanets (175 confirmed; 5,038 planet candidates🙌), it's also been scouting for @NASAWebb! Webb will make followup observations of some interesting exoplanets discovered by TESS. Go, space team!

End the year (or start the new one) feeling a little bit smarter with Exo 101: Everything you need to know about exoplanets. Learn about mysterious worlds and how @NASA is searching for life beyond Earth. https://t.co/XOcBhbRUjy

When it launches🚀 later this year, @NASAWebb🛰 will be the most complex – and powerful – space science observatory ever. We can’t wait! Get ready with our new poster: https://t.co/4BG7Lk0bSP

Space telescopes are the extension of humanity into the farthest reaches. They are the eyes that allow us to see beyond what is ''visible.'' They are the best of us. This week we'll release the final poster in our mission series. Can you guess who's next? https://t.co/fJvd5gJmk7

For more than 30 years, @NASAHubble has brought the cosmos down to Earth. It also discovered faraway worlds and told us more about them. Get our new free poster celebrating @NASA’s intrepid explorer! https://t.co/YaSa52KE84
