The Whirlpool Galaxy is about 23 million light-years away and is roughly the size of the Milky Way at about 60,000 light-years in diameter. It was discovered by Messier in October 1773. Sixty-four years later, Ireland's William Parsons ('Lord Rosse') first observed The Whirlpool's spiral structure with his Leviathan Reflector. Discovered in 1773 by Charles Messier, M51 was first observed in detail in 1845 by William Parsons, the 3rd Earl of Rosse, with his 72″ reflecting telescope at Birr Castle in Ireland. Lord Rosse simply called M51 a “spiral nebula,” not realizing that the glowing spiral-shaped object was a faraway galaxy brimming with innumerable stars.

He had to invent many of the techniques he used for constructing the Leviathan, both because its size was without precedent and because earlier telescope builders had guarded their secrets or had not published their methods.

In 1845 Rosse and his technicians claimed to have resolved the Orion nebula into its individual stars using the Leviathan, a claim which had considerable cosmological and even philosophical implications, as at the time there was considerable debate over whether or not the universe was "evolved" (in a pre-Darwinian sense), a concept which the nebular hypothesis supported and with which Rosse disagreed strongly. 1.1k.

Now known to be a spiral galaxy, Messier 51, the Whirlpool Galaxy, is one of the most well-studied galaxies beyond our Milky Way. Rosse himself did not believe that nebulas were truly gaseous, arguing rather that they were made of such an amount of fine stars that most telescopes could not resolve them individually (that is, he considered nebulas to be stellar in nature). Details of the metal, casting, grinding and polishing of the 3-ton 'speculum' were presented in 1844 at the Belfast Natural History Society.

Very cool sketch by astronomer Lord Rosse of the whirlpool galaxy. He built several giant telescopes. A main component of Rosse's nebular research was his attempt to resolve the nebular hypothesis, which posited that planets and stars were formed by gravity acting on gaseous nebulae. Kaushik Patowary Jul 8, 2016 1 comments. Eventually, neither man (nor telescope) could establish sufficiently scientific results to resolve the question (the convincing evidence for the gaseous nature of the nebula would be developed later from William Huggins's spectroscopic evidence, though it would not immediately resolve the philosophical issues).
