American astronomer and popularizer of science.
We are all connected by a single history. We are stardust contemplating the stars
There are billions of galaxies with billions of stars each. On each, the possibility of life
Orbits are ellipses, not circles. The harmony ran deeper than Kepler imagined
We are a way for the cosmos to know itself. We are points of the universe experiencing itself
Science is a way of thinking far more than a body of knowledge. It's a skeptical inquiry
We are made of stars. We are literally born from stellar explosions
The cosmos is vastly larger, older, and more indifferent to us than we ever imagined
Consider again that dot. That's here. That's home. That's us.
