On February 22, 2017, NASA announced that one of their telescopes in Belgium revealed seven Earth-sized planets about 40 light-years away. This planetary system is located around an ultra-cool dwarf star called Trappist-1 named after the telescope used for their discovery. Three of these planets are located in the habitual zone but since the planets are all extremely close to each other they all have a possibility of water. Not to mention that from the surface of these planets you could easily see the others in the sky. With the launch of NASA’s new telescope in 2018 they will be able to detect if the planets have chemical fingerprints of water, methane, and oxygen which are key to the creation of atmospheres and making the planets habitability. With these seven new planets NASA has taken to twitter to see what people want to call them. I thought this was a great example of crowd sourcing that we talked about this past week. The first links down below are for the video I used and the second is if you guys wanted more information about how NASA discovered these planets.
