All astronomer want to see the Andromeda Galaxy (M31). Our beginner's guide to finding the Andromeda Galaxy makes it really simple!

Messier 31 or M31 (also designated NGC 224) is a spiral galaxy in the constellation Andromeda. It has an apparent visual magnitude of 3.4 and its angular diameter is 178x63 arc-minutes. M31 lies at an estimated distance of 2.9 million light years.

2024年12月7日 · The Andromeda Galaxy (Messier 31 or M31) is a barred spiral galaxy. M31 features a large central bulge, bar-shaped structure, and two main spiral arms with arms and spurs. The galaxy measures 220,000 light-years in diameter.

Explanation: The most distant object easily visible to the unaided eye is M31, the great Andromeda Galaxy. Even at some two and a half million light-years distant, this immense spiral galaxy -- spanning over 200,000 light years -- is visible, although as a faint, nebulous cloud in the constellation Andromeda.

1993年7月20日 · A NASA's Hubble Space Telescope (HST) image of a "double nucleus" in the giant spiral galaxy in Andromeda, M31. Each of the two light-peaks contains a few million densely packed stars. The brighter object is the "classic" nucleus as studied from the ground. However, HST reveals that the true center of the galaxy is really the dimmer component.

2024年2月24日 · The Andromeda Galaxy, also known as M31, is a beautiful spiral galaxy that lies approximately 2.5 million light-years away from our Milky Way Galaxy. It is one of the closest galaxies to ours, and it is visible to the naked eye in the night sky.

M31, the great Andromeda Galaxy, is one of the most famous objects in the entire sky, and the nearest of all spiral galaxies. This object was first mentioned by the Persian astronomer Al Sufi in the 10th Century, but the world became aware of its existence only in 1764 when Charles Messier included it in his catalogue .

2017年3月16日 · Using an 8-inch (200mm) telescope, M31 presents a spectacular sight with its diffuse dust lanes stretching out from its bright center, and if these vast spiral arms are included, the Andromeda Galaxy would cover around 20 degrees of sky, or 40 full Moons.

The Andromeda Galaxy with M110 at upper left and M32 to the right of the core. The Andromeda Galaxy (M31) has satellite galaxies just like the Milky Way.Orbiting M31 are at least 35 dwarf galaxies [1]: the brightest and largest is M110, which can be seen with a basic telescope.The second-brightest and closest one to M31 is M32.The other galaxies are fainter, and were …

1 天前 · This is a wide-angle view of the distribution of known satellite galaxies orbiting the large Andromeda galaxy (M31), located 2.5 million light-years away. The Hubble Space Telescope was used to study the entire population of 36 mini-galaxies circled in yellow. Andromeda is the bright spindle-shaped object at image center.

The great galaxy in Andromeda shines at mag. 3.5. This beautiful spiral galaxy is the most distant object visible to the naked eye, yet the closest major galaxy to the Milky Way, about 2,200,000 light years away.

2013年6月12日 · Andromeda, also known as Messier 31 (M31), is a spiral galaxy located about 2.5 million light years away. It is thought that the Milky Way and Andromeda will collide several billion years from now. The black holes located in both galaxies will then reside in the large, elliptical galaxy that results from this merger.

The most distant object easily visible to the unaided eye is M31, the great Andromeda Galaxy, over two million light-years away. Without a telescope, even this immense spiral galaxy appears as an unremarkable, faint, nebulous cloud in the constellation Andromeda.

La Galassia di Andromeda (nota talvolta anche con il vecchio nome Grande Nebulosa di Andromeda o con le sigle di catalogo M 31 e NGC 224) è una grande galassia a spirale barrata che dista circa 2,538 milioni di anni luce dalla Terra [7] [4] in direzione della costellazione di Andromeda, da cui prende il nome.Si tratta della galassia di grandi dimensioni più vicina alla …

The most distant object easily visible to the unaided eye is M31, the great Andromeda Galaxy, over two million light-years away. Without a telescope, even this immense spiral galaxy appears as an unremarkable, faint, nebulous cloud in the constellation Andromeda.

2025年2月28日 · The proximity of the Andromeda Galaxy to the Milky Way would have seen material ripped out of our galaxy to settle in the same orbital plane around the Andromeda galaxy and form the dwarf galaxies ...

2018年12月17日 · Andromeda is frequently referred to as M31 since it is the 31st object on Messier's list of diffuse sky objects. M31 is so distant it takes about two million years for light to reach us from there. Although visible without aid, the …

The diffuse light from Andromeda is caused by the hundreds of billions of stars that compose it. The several distinct stars that surround Andromeda's image are actually stars in our Galaxy that are well in front of the background object. Andromeda is frequently referred to as M31 since it is the 31st object on Messier's list of diffuse sky objects.
