This Flammarion engraving, by an unknown artist, is called Empedocles Breaks through the Crystal Spheres. It first appeared in Camille Flammarion’s 1888 book L’atmosphère: météorologie populaire (The Atmosphere: Popular Meteorology) with the caption: “A missionary of the Middle Ages tells that he had found the point where the sky and the Earth touch …”

February 19, 1473. This is the birthday of Nicolaus Copernicus, a Renaissance astronomer and mathematician who sparked the revolution in cosmology that’s still going on today.

Copernicus - Time - People - Earth - Spheres

Copernicus was born at a time when people believed Earth lay enclosed within crystal spheres at the center of the universe. Can you picture the leap of imagination required for him to conceive of a sun-centered universe? The publication of Copernicus’ book – De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres) – just before his death in 1543, set the stage for all of modern astronomy.

Today, people speak of his work as the Copernican Revolution.

Years - Word - Google - Copernicus - Birthday

A few years ago, if you searched on the word “Google” on Copernicus’ birthday, you’d have found an animated version of a Google Doodle celebrating a sun-centered cosmos. Google uses Google Doodles to showcase holidays, famous birthdays and so on. Not sure if they’re using this doodle this year or not. Search and see! Or see the video below, which also features the Copernicus Google Doodle. Thank you to EarthSky Facebook friend...
