Illustration of the Whirlpool Galaxy (M51,NGC 5194) made by William Parsons the third Earl of Rosse (1800-1867). Rosse,an Irish astronomer and telescope builder,made this illustration by using a giant reflecting telescope which he built and that became known as the "Leviathan of Corkstown". The telescope was 15m long and had a primary mirror with a diameter of 1.8m. With this instrument he was the first to recognise the spiral shape of some fifteen nebulae,including M51. This illustration was taken from a paper written by Rosse which was published in 1850 and entitled "Observations on the Nebulae" | |
