 "This is a niche in the electromagnetic spectrum that hitherto has not been really sampled."-Ian Wong


Starts at 2:35. Spectroscopy is the basis of astronomy. Telescopes penultimate tequnique. This camera sees a bigger spectra than Hubble can. Spectroscopy sometimes follows probes. The probes tell the engineers what an instrument planetary science to look for. JWST is the machine previous probes demanded.

Overall this is mostly a teaser lecture. Promises of epiphanies JWST will produce. The slides are eye-candy, the lecture meanders. 

  • Slide at 6:25 illustrates the topic. JWST is looking at spectra we haven't had a good telescope for.
  • 15:40, JWST seeing DART hit the board.
  • 21:50, Jupiter Aurora, IO flux tube, Ganymede magnetosphere, JWST is perfect for studying these things.
  • 30:10. Titan stuff. Mostly teaser, that color structure exists at all is proof spectroscopy has a lot to work with.
  • 33:20, Uranus. Seems like yesterday we were arguing over which would get a probe next. Now they seem so far away. JWST will have to do.
  • 35:50 Neptune and Triton. JWST will pay off there too.

  "Best case scenario to be modeled." -Peter Jenniskens This is mostly a storybook slideshow. So it's pretty entertaining, but...
