There is a powerful recognition that stirs within us when we see our little blue ocean planet in the skies of other worlds. In an instant we can see how small, fragile, and alone we all really are.

Saturn is the most photogenic planet in the solar system.

While I was there, Voyager flew by Saturn. I got involved with a person who was a member of the imaging team and started working on data from Saturn. With all that data coming in, the imaging team didn't have enough hands or scientists to work on all of it.

Spokes are one of those Saturn-system phenomena that we are keenly interested in understanding.

All the atoms of our bodies will be blown into space in the disintegration of the solar system, to live on forever as mass or energy. That's what we should be teaching our children, not fairy tales about angels and seeing grandma in Heaven.

The same spiritual fulfillment that people find in religion can be found in science by coming to know, if you will, the mind of God.

Being a scientist and staring immensity and eternity in the face every day is as grand and inspiring as it gets.
