“It's feasible that we'll meet other sentient life forms and conduct commerce with them. We don't now have the technology to physically travel outside our solar system for such an exchange to take place, but we are like Columbus centuries ago, learning fast how to get somewhere few think possible.”
“We do care about planets like the Earth because by now we understood that life as a chemical system really needs a smaller planet with water and with rocks and with a lot of complex chemistry to originate, to emerge, to survive.”
“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.”
“I grew up in Bulgaria in a small city on the Black Sea Coast, so I was very interested in the sea, marine life, and everything related to it. But it was also a very dark place at night, so I could see the stars. And I just got very interested in it.”
“Life is extremely resilient once it takes hold, but it requires rich chemistry, large energy sources, and stability, right from the beginning. The comparative planetology of our solar system makes it seem like those initial conditions are hard to come by.”
“My parents gave me a small telescope, then I built my own, and one thing led to another. So that's how I ended up going from being a hobby astronomer to a professional astronomer.”
“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.”
“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.”
“The question we ask is - if there is life on other planets, should we expect it to be based on the same molecules, i.e. be universal - or should we expect it to depend on the local conditions, i.e. on the planet's geochemistry. So to find out, we try experiments on biomolecules, starting with such geochemistry conditions.”
“In science, it is rare that a transformational change occurs during our lifetimes.”
