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. |

Interesting! The two nebulae and Stephan’s Quintet should be impressive eye candy, and also scientifically interesting as common examples of their type of object, imaged for the first time with JWST.
The deep field image using gravitational lensing is an interesting complicated case. I don't think anyone could say with certainty what that will reveal until it's been seen. WASP-96 b, rather than being a particularly challenging exoplanet to study, is a relatively easy one (strong signal) that's been partially characterized already. So, rather than JWST providing some low-signal data from a new class of exoplanet, it should probably offer some really good characterization of a planet that we already know something about. 1.5 days left to wait. |
