Priests opposed his theory that earth revolved around the sun

Frombork, Poland: Nicolaus Copernicus, the 16th-century astronomer whose work was condemned by the Catholic Church as heretical, was reburied by Polish priests as a hero yesterday, nearly 500 years after he was laid to rest in an unmarked grave.
His burial in a tomb in the cathedral where he once served as a church canon and doctor indicates how far the church has come in making peace with the scientist whose revolutionary theory that the Earth revolves around the Sun helped usher in the modern scientific age.
Copernicus, who lived from 1473 to 1543, died as a little-known astronomer working in what is now Poland, far from Europe's centres of learning. He had spent years labouring in his free time developing his theory, which was later condemned as heretical by the church because it removed Earth and humanity from their central position in the universe.
After his death, his remains rested in an unmarked grave beneath the floor of the cathedral in Frombork, northern Poland, the exact location unknown.
At the urging of a local bishop, scientists began searching in 2004 for the astronomer's remains and eventually turned up a skull and bones of a 70-year-old man — the age Copernicus was when he died.
