James Bradley was an English astronomer. He was born in 1692 at Sherborne, and died in 1762. He studied theology at Oxford, and took orders; but devoting himself to astronomy he was appointed, in 1721, professor of that science at Oxford. Six years afterwards he made known his discovery of the aberration of light, and his researches for many years were chiefly directed towards finding out methods for determining precisely that aberration. It is largely owing to Bradley's discoveries that astronomers have since been able to make up astronomical tables with the necessary accuracy. In 1741 he was made Astronomer Royal and removed to Greenwich. Research James Bradley
