O Trappist-1, O Trappist-1, how lovely are thy planets!

We know you are all eagerly awaiting Webb's look at this system of 7 Earth-sized worlds. The telescope has observed all the planets, and preliminary results (including atmospheric properties) will be out in the new year!

Using light that has passed through the atmosphere of these planets during their occlusions of their home stars, we can literally determine atmospheric composition using a spectrometer. Each element gives a unique spectrographic result. We can read atmospheric composition from hundreds of lightyears. Fucking awesome.

Also, any rocket surgeons, feel free to correct any mistakes in my understanding. I am but a lowly history major.
