Dimitar Sasselov Planet Quotations

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.

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.

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.
