M2 is approximately 37, light years distant and has an apparent magnitude of 6. The brightest stars in the cluster, mostly red and yellow giants, have a magnitude of Charles Messier discovered the cluster in , but believed it to be a nebula.
German astronomer William Herschel was the first to resolve the stars in the cluster in Messier 72 is also a globular cluster, approximately 53, light years distant. It lies well beyond the Galactic Centre. It is about light years in diameter and has an apparent magnitude of 9. It contains several blue giant stars and is considered to be a young cluster. It also has a significant number of variable stars, 42 known ones, mostly RR Lyrae type.
The brightest star in the cluster has an apparent magnitude of Both he and Charles Messier, who included the cluster in his catalogue, believed the object to be a faint nebula. The cluster is not an easy one to observe. In a inch telescope, it appears only as a faint patch. The stars can, however, be resolved in a inch telescope. M72 is located three degrees to the south and 1. Messier 73 is an asterism of four stars that appear close to each other in the night sky, but are really not connected.
Messier 73, image: Sloan Digital Sky Survey. Charles Messier discovered the object in and described as a cluster of four stars with some nebulosity. English astronomer John Herschel was not entirely convinced that M73 was a cluster, but included it in his General Catalogue of clusters, nebulae, and galaxies.
It got its name from the English astronomer and telescope maker William Parsons, 3rd Earl of Rosse, in the 19th century. The spectacular planetary nebula NGC , or the Saturn Nebula, emerges from the darkness like a series of oddly-shaped bubbles, lit up in glorious pinks and blues. Walsh, September In larger telescopes, its shape appears similar to that of the planet Saturn.
The nebula is located a degree to the west of Nu Aquarii. The Saturn Nebula is a planetary nebula that formed when a low-mass star evolved into a bright white dwarf. The central star has a luminosity of about 20 Suns and an apparent magnitude of Its temperature is about 55, K.
It is a large planetary nebula, one of the closest bright nebulae to Earth. It is approximately light years distant. Because of its appearance, the nebula has earned the nickname the Eye of God. The nebula is 2. It is located a degree to the west of Upsilon Aquarii. In small telescopes, it appears as a faint patch of light, but bigger ones 6-inch will reveal a dark centre with a star.
The Aquarius Dwarf is an irregular dwarf galaxy and a member of the Local Group of galaxies. It is approximately 3. Atoms for Peace Galaxy, catalogued as NGC , is a peculiar elliptical galaxy, approximately million light years distant. It is believed to be the product of a collision between two disk galaxies roughly a billion years ago. The galaxy has an apparent magnitude of The stunning Atoms for Peace galaxy was given its nickname due to its superficial resemblance to an atomic nucleus, surrounded by the loops of orbiting electrons.
