HAPPY BIRTHDAY Isaac Newton
Born December 25, 1642 (on the Julian Calendar in use at the time in England) who, by the age of 30, would transform civilization, showing that the universe was mathematically knowable and predictable.

We just can’t get enough Saturn! In this video, 20 hours of Hubble observations are combined to show the rotation of Saturn and the revolution of six of its moons.
Listening to @NeilTyson reading Astrophysics for People in a Hurry makes me think of this lovely quote from Carl Sagan: “When you’re in love you want to tell the world. This book is a personal statement, reflecting my lifelong love affair with science.” (Carl Sagan).
In 1610, Galileo peered at Jupiter through a telescope and saw 4 small moons. This was the first observation of worlds that conclusively orbited something other than Earth, revolutionizing our understanding of the cosmos.
