Quotes by Dimitar Sasselov
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.
Super-Earths are how we call a family of planets... up to two times larger and about ten times more massive than the Earth.
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.
People quite often think of the question 'Are we alone in the universe?' in terms of other civilizations out there: life forms that have reached at least our level of technological development.
When we think of what is necessary for the phenomenon that we call life, we think of compartmentalization, keeping the molecules which are important for life in a membrane, isolated from the rest of the environment, but yet, in an environment in which they actually could originate together.
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.
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.
There is immense, powerful potential in life in this universe - especially now that we know that places like the Earth are common. And that potential, that powerful potential, is also our potential, of you and me.
Ocean planets might be very common in the universe because water is very common in the low-temperature environments where planets form and evolve. This might be especially true for super-Earths, which can retain volatiles more easily thanks to their larger mass and surface gravity.
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.
