My father was not only a planetary scientist and a great popularizer of science, but he thought very deeply about the world. He was a scholar, he studied history. He taught a class in critical thinking, and he was very, very aware of the directions we might go.

Dad was a difference maker. He reached out to people. He took them by the awe and wonder we feel over the most important questions we can think to imagine. He pulled them away from blind faith, away from pseudoscience, toward a deeper, richer understanding of the universe.

Life in space is impossible,' we're warned, and amidst the hypnotic beauty of these heavens, we become painfully aware of what a hostile environment space is, how unforgiving, how unsympathetic to human desires.

Astonishingly powerful and poignant, 'Gravity' is the rarest of rares: a space survival film informed by a genuine reverence for the awe-inspiring cosmos we inhabit.

Something my father dearly loved is the scientific method, and it's founded in this element of humility. The idea is that you pursue the truth wherever it goes; you need to evidence, and you can - you see if it's repeatable.

It goes back to the starfish. That's when the light bulb really popped over my head. We'd found one on the beach, and I was struck by what astonishing creatures they are, talking with Dad about how they regenerate.

Dad was a world-famous astronomer; Mom was the artist who drew the iconic Pioneer plaque.

I've met secular humanists who grew up in evangelical households, for whom 'Cosmos' was their first exposure to a scientific way of viewing the world.

Bringing the astronaut's nightmare to life so vividly is a remarkable accomplishment but Alfonso and Jonas Cuaron want more than just the adrenaline ride - they're feeding our wonder and inviting us to think deeply about profound questions of existence.

American sci-fi has fallen into the doldrums in part because of the anti-science sentiment that's so prevalent in our culture lately.

I'm thrilled to be working with the Science Channel. A chance to shine a light on the wonder and exciting possibilities of science with such a smart and talented team is a dream come true for me. It's very gratifying to me personally, and it's also a way to honor my family.

We're so bitterly divided these days, the appearance of a true 'other' might be the best chance of bringing us all together.
