Why is the James Webb telescope so expensive?
That's why JWST is so expensive. Because we've spent two decades building and testing every single piece a million ways to do everything to make sure it doesn't have problems
What will James Webb be able to see?
Unlike Hubble, it will be able to see right into “stellar nurseries” , where stars and their planetary systems are being born. The observations will answer questions about how the clouds of dust and gas collapse to form stars and how planetary systems form around them.
