"We've sent out one or two little messages, but we certainly aren't investing billions of dollars shouting out into the cosmos saying, "Hey, we are here. Come say hi.""

The ocean is evolving, and it’s not based on the ‘survival of the fittest.’ Astrobiologist Betül Kaçar explains how it’s not competition that has kept the ocean alive, but collaboration.

We may be close to finding life beyond Earth. But would we even recognize it if we did? Astrobiologist Betül Kaçar explains what signs NASA is looking for.

"If we did create beings that were more like non-human animals, we ought to treat them much better than we now treat non-human animals."

These microbes endured the unlivable. The NASA astrobiologist who studies them reveals what that means for us today

"If we're related to every living thing on the planet, do we not have a special responsibility for every living thing on this planet? They are really all our relatives."

“When you think about this interconnection of all these tiny causes and effects which add up to the way the world unfolds, it becomes impossible to imagine that we have complete control.”

“It's a remarkable series of events that were required for us to be here, and that so many things could have happened in a different way that we wouldn't be here at all, both individually, and as a species.”

“We are beginning to take our first steps out into the cosmic ocean… and the water seems inviting.”

“We don't have enough knowledge to precisely calculate what is going to happen, and so we assign probabilities to it, which reflects our ignorance of the situation.”

"Asking the question of, "Where did the entire universe come from?" is no longer a question for poets and theologians and philosophers. This is a question for scientists, and we have some amazing scientific answers to this question."

"What would a totalitarian society that is not well disposed to our own do if it had God-like power? We don't wanna find out."
