Her most significant contributions to astronomy were the discoveries of several comets and in particular the periodic comet 35P. She was the first woman to be paid for her contribution to science, to be awarded a Gold Medal of the Royal Astronomical Society and to be named an Honorary Member of the Royal Astronomical Society. William Parsons, the 3rd Earl of Rose, (1800–1867) was an Anglo-Irish astronomer who made several large telescopes. His 72-inch telescope, the "Leviathan", built in 1845, was the world's largest telescope until the early 20th century. Rosse's telescope was considered a marvelous astronomical and engineering achievement. A main component of Rosse's nebular research was attempting to resolve the nebular hypothesis, which posited that planets and stars were formed by gravity acting on gaseous
