What I want to look at with Webb is what we call ice giants in our solar system - the planets Neptune and Uranus.
Even after years of observing, a new picture of Uranus from Keck Observatory can stop me in my tracks and make me say, 'Wow!'
We really have only been observing Neptune with big telescopes since shortly before 1989.
No one planet can tell us everything about the universe, but Neptune seems to hold more than its share of information about the formation of our own solar system - as well as the solar systems beyond.
When Hubble was launched, it became clear very shortly thereafter that there was a problem with the optics.The mirror was not quite the right shape. And the one program that I had really been looking forward to doing with Hubble was studying outer planets in our solar system, the planets Uranus and Neptune.
You have to budget time for the inevitable problems that come up with children. You have to always be ahead of the game. If your proposal is due at NASA on Friday, it has to be finished on Wednesday because, on Thursday, it could be fevers and head lice.
