NOVA New Eye on the Universe - JWST preliminary results

.

I watched the recent NOVA program about the JWST and the first results of various investigations.  One thing is that PBS Wisconsin has moved NOVA to the 9 pm time slot from 8 pm.  Why does this matter ? see:

Yes it happened again, about 1/2 way through I nodded off.

Luckily PBS does also post NOVA to Youtube so I can rewatch the show:

The part about the calibration of the image sensors was interesting, I would have thought that this would have been nailed down on the ground but apparently they need to be done in space on the system as a whole using a standard set of stars.

After almost a year a confirmation of NOVA as a safe, effective, low cost sleep aid :)
