Discovery of the aberration of light (1727–1728 observations)
Discovery of the aberration of light (1727–1728 observations) is James Bradley’s landmark astronomical finding that revealed the apparent shift in stellar positions due to Earth’s motion, providing strong evidence for heliocentrism and the finite speed of light.
