Google is celebrating the 540th birth anniversary of Polish astronomer Nicolaus Copernicus with a doodle. The doodle depicts the sun at the center with Mercury, Venus, Earth, Mars, Jupiter and Saturn revolving around it, depicting the heliocentric model formulated by him. Copernicus was the first astronomer to suggest that the sun is at the center of the universe and that Earth and other planets revolved around it, challenging the Church, which maintained the Earth as flat and the center of the universe.
At the time, only five other planets were known and that the moon revolver around the Earth, which is animated in the doodle. The sun is depicted in the second ‘o’ of Google, while the rest of the logo is present in Google’s typical Catull font. Unlike some recent doodles, Copernicus’s doodle is not interactive and clicking it leads to a search query for the famous astronomer.
His treatise “On the Revolution of the Celestial Spheres” was not published until the year of his death in 1543. His treatise was followed by future scientists like Kepler and Galileo, among others.
