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.Collection: Space
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.Collection: Home
My parents gave me a small telescope, then I built my own, and one thing led to another. So thats how I ended up going from being a hobby astronomer to a professional astronomer.Collection: Parent

Deep and elegant explanations relate to natural or social phenomena and the observer often has no place in them.Collection: Natural
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.Collection: Rocks
In science, it is rare that a transformational change occurs during our lifetimes.Collection: Lifetime
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.Collection: Discovery
Life and the universe compare to each other like a child and a parent, parent and offspring.Collection: Children
