It feels great to discover a planet, just like any discovery in science, except that it has more of the feel of exploration - you can go back and look at it. However, I can never visit.

Super-Earths are how we call a family of planets... up to two times larger and about ten times more massive than the Earth.

When we discover New Earth - a planet we could call home - the question of the 'plurality of worlds' will come front and center, reminding us yet again that we are not the center of the universe.

We love our planet Earth. We should - it is our home, and there's no place like home. There can't ever be a better place than Earth.

It's very important for us to see that science is done by people, not just brains but whole human beings, and sometimes at great cost.

Any teaching of falsehoods in science classes should certainly be identified and stopped by school inspectors. School inspectors should be looking at science teachings to make sure they are evidence-based science.

I just had a crazy, wild imagination all my life, and science fiction is the greatest outlet for me.

As you continue to work on a show, if I still feel inspired, and I feel they are making exciting choices, then our enthusiasm remains. This is not a perfect science. It's an evolutionary process.
