@JacksonBTT Splitting the sunshield into 5 layers allows heat to radiate out from between them, causing each successive layer to be cooler than the one below. The vacuum of space between each layer also acts as a great insulator. Learn more about the sunshield design: https://t.co/j1nRsAwHOL — PolitiTweet.org

Why is @NASAWebb's sunshield shaped like a kite? In short, it's exactly the shape & size it needs to be. The iconic profile lets the telescope tilt back and forth to observe more of the universe. Plus, it helps radiate heat from the sides. Take a look: https://t.co/YhpDZdWLb8 https://t.co/TjCXoFivq9 — PolitiTweet.org
