The andromeda galaxy is a _ _ galaxy

Andromeda is one of 48 constellations described by the Ancient Greek astronomer Claudius Ptolemy in 150 AD in his famous work "The Almagest." Ptolemy's list was the first official description of constellations, although these stellar groupings had been known to ancient Greeks, Babylonians, Egyptians and other cultures, who frequently saw them as embodiments of their mythical figures. When to observe the Andromeda constellation The Andromeda constellation can be best viewed from the Northern Hemisphere, as it moves lower toward the horizon the farther south you stand. At about 40 degrees south latitude it disappears completely, according to EarthSky. (The 40th parallel south lies just below the southern tips of Africa and Australia and crosses the southernmost part of South America). In the Northern Hemisphere, Andromeda is best observed from August to February, while in the Southern Hemisphere, the visibility period is much shorter, from October to December, according to PlanetGuide. From August to September, in the Northern Hemisphere, Andromeda emerges on the north-eastern horizon at about 10 p.m. local time, then gradually rises overhead. From October to November, it emerges in the eastern sky at around 8 p.m. From December to January, Andromeda rises at around 6 p.m. and moves along the northwestern horizon, according to Planet Guide. The position of the Andromeda constellation among the other constellations named after characters related to the Perseus myth. (Image cr...

The Andromeda Galaxy is the second most famous galaxy in astronomy, after our home galaxy, the Fortunately, we know a lot about the Andromeda Galaxy now, and it has become an object of endless fascination in both astronomy and popular culture. But how did we go about discovering it in the first place? How were we able to tell it was a galaxy like our own? Will we ever be able to visit it one day, and do we know if Andromeda can support life? What is the Andromeda Galaxy? The Since its apparent magnitude is 3.4, it is visible to the naked eye on a clear and dark night, so it isn't possible to say who "discovered" it, though the earliest known record of it appears in 964 CE in the Book of the Fixed Stars by the Persian astronomer Abd al-Rahman al-Sufi. The American astronomer Edwin Hubble was the first person to have conclusively demonstrated that Andromeda was a separate galaxy apart from our own in 1925, and not a nebula as previously believed. The Andromeda Galaxy is also of particular importance to astronomers since it bears a lot of similarities to our own galaxy, and is the most distant object in the universe that is visible to the naked eye. Andromeda Galaxy or Andromeda Nebula? A photograph of the Great Nebula of Andromeda, now known as the Andromeda galaxy, taken in the late 19th century. | Andromeda is our largest and nearest galactic neighbor, and for centuries, it was believed to be a nebula of little significance. French astronomerCharles Messier cataloged the "...

The stars of constellation Andromeda and the magnificent neighboring galaxy M31 rise above the highest peak of Mount Gongga, Sichuan province, China. Credit: Jeff Dai Using binoculars, you’ll find the galaxy with little or no difficulty. It will be oval in appearance – although you won’t be able to make out any of the individual stars within it. The Milky Way, Cassiopeia and the Andromeda Galaxy in the night sky, captured by Danny Cameron from Patna, UK, October 2016. Take our tour of the Andromeda Galaxy below with your telescope and discover its most intriguing sights. These targets can be seen with a refractor under 4 inches or a reflector/SCT under 6 inches. Search around the Andromeda Galaxy M31 to observe galaxies M32 and M110, plus the star cloud NGC 206 and globular cluster G1. Credit: Pete Lawrence Observe how far M31’s core extends from the galaxy’s centre. One measure for this is satellite galaxy M32 which sits 24 arcminutes south of M31’s star-like core. 3 M110 Like M32, M110 is another gravitationally bound satellite galaxy of M32 and another elliptical galaxy. It appears fainter and more elongated than M32, M32 being classed as type E2 while M110 is type E6p. M110 sits 35 arcminutes northwest of the centre of M31, 1.5x the apparent distance of M32 from the centre of M31’s core. NGC206 is a star-forming region in the Andromeda galaxy surrounded by dark dusk lanes. Credit: Martin Griffith We return to the main galaxy for our next object, NGC 206, a bright star ...
