Saturn Nebula
The Saturn Nebula (also known as NGC 7009 or Caldwell 55) is a planetary nebula in the constellation Aquarius. It appears as a greenish-yellowish hue in a small amateur telescope. It was discovered by William Herschel on September 7, 1782, using a telescope of his own design in the garden at his home in Datchet, England, and was one of his earliest discoveries in his sky survey. The nebula was originally a low-mass star that ejected its layers into space, forming the nebula. The central star is now a bright white dwarf star of apparent magnitude 11.5. The Saturn Nebula gets its name from its superficial resemblance to the planet Saturn with its rings nearly edge-on to the observer. It was so named by Lord Rosse in the 1840s, when telescopes had improved to the point that its Saturn-like shape could be discerned. William Henry Smyth said that the Saturn Nebula was one of Struve's nine "Rare Celestial Objects". The Saturn Nebula is a complex planetary nebula and contains many ...

In ancient Greek religion and mythology, the Muses ( grc, Μοῦσαι, Moûsai, el, Μούσες, Múses) are the inspirational goddesses of literature, science, and the arts. They were considered the source of the knowledge embodied in the poetry, lyric songs, and myths that were related orally for centuries in ancient Greek culture. Melete, Aoede, and Mneme are the original Boeotian Muses, and Calliope, Clio, Erato, Euterpe, Melpomene, Polyhymnia, Terpsichore, Thalia, and Urania are the nine Olympian Muses. In modern figurative usage, a Muse may be a source of artistic inspiration. Etymology The word ''Muses'' ( grc, Μοῦσαι, Moûsai) perhaps came from the o-grade of the Proto-Indo-European root (the basic meaning of which is 'put in mind' in verb formations with transitive function and 'have in mind' in those with intransitive function), or from root ('to tower, mountain') since all the most important cult-centres of the Muses were on mountains or hills.

Lord Rosse
William Parsons, 3rd Earl of Rosse (17 June 1800 – 31 October 1867), was an Irish astronomer, naturalist, and engineer. He was president of the Royal Society (UK), the most important association of naturalists in the world in the nineteenth century. He built several giant telescopes. His 72-inch telescope, built in 1845 and colloquially known as the "Leviathan of Parsonstown", was the world's largest telescope, in terms of aperture size, until the early 20th century. From April 1807 until February 1841, he was Style (manner of address), styled as Baron Oxmantown. Life He was born in York, England, the son of Sir Lawrence Parsons, later 2nd Earl of Rosse, and Alice Lloyd. He was educated at Trinity College Dublin and Magdalen College, Oxford, graduating with first-class honours in mathematics in 1822. He inherited an earldom and a large estate in County Offaly, King's County (now County Offaly) in Ireland when his father, Lawrence Parsons, 2nd Earl of Rosse, Lawrence, 2nd Earl ...
