Hubble might not be able spot what JWT can see. Everything we can detect or see, we have catalogs of as well as their locations or coordinates, but this changes all that. They're going to need bigger catalogs.
I hope the images reveal some spectacular objects...or maybe something beyond spectacular.
Correct, but it can find areas of interest to explore in greater detail with JW. Thats how I heard they will use zhubble until it stops working for one reason or another.
They already have a list of places for JW to look at from certain areas Hubble has previously been pointed at.
