Andromeda Galaxy photographed in 1899 The Andromeda Galaxy (also known as Messier 31, M31, or NGC 224; older texts often call it the Andromeda Nebula) is a giant spiral galaxy in the Local Group, together with the Milky Way galaxy. It is at a distance of approximately 2.5 million light years or 770 kpc, in the direction of the constellation Andromeda. With a mass of about 1.5 times that of the Milky Way, it is the dominant galaxy of the Local Group, which consists of about 30 sma ...

The Andromeda Galaxy was observed in 964 by the Persian astronomer 'Abd Al-Rahman Al Sufi, who described it as a "small cloud". The first description of the object based on telescopic observation was given by Simon Marius (1612), who is often wrongly credited as the discoverer of the Andromeda Galaxy. In 1885, a supernova (known as "S Andromedae") was seen in the Andromeda Galaxy, the first and so far only one observed in that galaxy. At the time, it was thought to be much less luminous and unrelated event calle ...

The Andromeda Galaxy is approaching us at about 300 kilometres per second, so it is one of the few blue shifted galaxies. Given our motion inside the Milky Way, one finds that the Andromeda Galaxy and the Milky Way are approaching one another at a speed of 100 to 140 kilometres per second. However, this doesn't mean it will collide with the Milky Way, since the galaxy's tangential velocity is unknown. If it is on a collision course, the impact is predicted to occur in about 3 billion years. In that case the two galaxies will merge to form a giant elliptical galaxy. Such ...

A nebula (Latin: "mist"; pl. nebulae) is an interstellar cloud of dust, gas and plasma. Originally nebula was a general name for any extended astronomical object, including galaxies beyond the Milky Way (some examples of the older usage survive; for example, the Andromeda Galaxy is sometimes referred to as the Andromeda Nebula).

Wilhelm Heinrich Walter Baade (March 24, 1893 - June 25, 1960) was a German astronomer who emigrated to the USA in 1931. Walter Baade - Biography. Along with Fritz Zwicky, he proposed that supernovae could create neutron stars. He took advantage of wartime blackout conditions during World War II, which reduced light pollution at Mount Wilson Observatory, to resolve stars in the center of the Andromeda galaxy for the first time, which led him to define distinct "populations" for stars (Population I an ...

In Greek mythology, Andromeda ("ruler of men") was the daughter of Cepheus and Cassiopeia, king and queen of the Ethiopians.

During the early twentieth century, science fiction writers began to consider the possible alteration of human beings and other species, either through the natural alteration of genes or by the use of deliberate genetic engineering. Stories of mutated humans first became common in the 1930s pulp magazines and in the British scientific romances of the time, mutation often providing the justification for stories of supermen. Such narratives provide scientifically rationalized accounts of the transformation of human beings and nature, a theme of timeless fascination, as shown by the man ...

The Lloigor take the form of invisible vortices of psychic energy, though they may sometimes manifest themselves as great reptilian beasts, akin to the mythical dragons of legend.

Like stars, most galaxies do not have names. There are a few exceptions such as the Andromeda Galaxy, the Whirlpool Galaxy, and others, but most simply have a catalog number. In the 19th century, the exact nature of galaxies was not yet understood, and the early catalogs such as the Messier catalog simply grouped together open clusters, globular clusters, nebulas, and galaxies. The Andromeda Galaxy is Messier object 31, or M31; the Whirlpool Galaxy is M51. The New General Catalogue (NGC) was a much larger catalog which contained thousands of objects.< ...
