Astronomer Casper Farret Jentink works deep in the forests above Geneva on one of the biggest questions humanity has ever asked itself: are we alone in the universe? We are born alone, we die alone, and in between we try to understand what it means to be there at all. In a workshop, half-observatory, half science fiction decor, astronomer Casper Farret Jentink builds instruments with Swiss precision that can accurately measure light from distant stars to five silicon atoms, in search of a second Earth.
