The manufacture of the JWST mirror blanks has now been completed.
Despite this milestone, the fate of JWST is still somewhat precarious, because although the scientific bang from the telescope is expected to be huge, the bucks required have increased to a staggering $4.5 billion. A Space.com article on the squeeze in NASA's space-based astronomy plans gives some background. The JWST home page can be found here. The Space Telescope Science Institute, which runs Hubble, also has a site here. As does ESA. |

A good summary of the various caveats for the claims of large, early galaxies in Webb images from S&T.
In short, we need proper spectroscopy and ratios of massive to light stars may differ in the distant past from today, and it'll take time to sort through this. |
