On this day in 1633 (Vatican inquisitors declare Galileo's heresy) : verdict on cosmology

from Writer's Almanac (American Public Media, Garrison Keillor):

On the date of June 22 in 1633, the Vatican ruled that Galileo Galilei was "vehemently suspect of heresy." Galileo supported Copernicus's theory of heliocentrism: namely that the Sun, not the Earth, was the center of the universe. All his books were banned, and he was placed under house arrest for the rest of his life.
Of course, Galileo's theory wasn't quite right either. We do revolve around the Sun, but the Sun is just one little yellow star on the arm of the spiraling Milky Way galaxy.
