Replying to a redditor:

> What are some of the bigger mysteries that the James Webb telescope is going to help us solve?

> It'll be able to see the formation of the first stars and galaxies (because it's sensitive in the infrared) - which will be very exciting. It'll also open up the possibility of analysing the atmospheres of exoplanets. The 'wild' but wonderful discovery would be oxygen in an atmosphere - which would look very much like photosynthesis ! There's lots more, but these are two capabilities that really go a lot further than Hubble.
