James Webb Space Telescope reveals Fomalhaut's disk in detail
As a layman I get the feeling that JWST is showing us more detailed things we'd already seen than brand new ones. I remember being moved by the Hubble deep field, where a long exposure revealed that what looked like an empty patch of the sky was anything but.<p>Are we reaching the point of diminishing returns of what a reasonably sized (for our current rockets) space telescope can see?
