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 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. Dimitar Sasselov Read Quote
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.

Life and the universe compare to each other like a child and a parent, parent and offspring. Dimitar Sasselov Read Quote
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. Dimitar Sasselov Read Quote
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. Dimitar Sasselov Read Quote
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. Dimitar Sasselov Read Quote
In science, it is rare that a transformational change occurs during our lifetimes. Dimitar Sasselov Read Quote
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. Dimitar Sasselov Read Quote
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. Dimitar Sasselov Read Quote
