![]() ![]() You need a good spot away from bright lights in order to see it. The signature of these galaxies is an elegant spiral pattern in the disk. The Andromeda Galaxy is the most distant object you can spot with the naked eye. The center of a spiral galaxy is something we call the Bulge, which is a very large group of stars, giving a super bright appearance. Spiral galaxies have three visible parts: a thin disk composed of stars, gas, and dust a central bulge of older stars and a spherical halo of the oldest stars and massive star clusters.Some of them are among the most densely populated globulars ever seen. There are at least 450 globular clusters orbiting in and around the Andromeda Galaxy. galaxy Table of Contents Galaxy - Elliptical, Spiral, Irregular: Almost all current systems of galaxy classification are outgrowths of the initial scheme proposed by the American astronomer Edwin Hubble in 1926.It has an apparent magnitude of 8.4 and can be spotted with a small telescope most easily during May. Discovered by Charles Messier in 1773, M51 is located 31 million light-years from Earth in the constellation Canes Venatici. Astronomers think that it may have interacted more closely with Andromeda several hundred million years ago, when M32 plunged through the heart of its larger neighbor. The blue color can be attributed to hot, young stars while the yellow color is from older stars. The Andromeda Galaxy has at least two spiral arms, plus a ring of dust that may have come from the smaller galaxy M32.The spiral arms of the Andromeda Galaxy are being distorted by gravitational interactions with two companion galaxies, M32 and M110.Not only does it have a massive star cluster right at its heart, but it also has at least one supermassive black hole hidden at the core. The Andromeda Galaxy has a very crowded double nucleus.The Andromeda Galaxy is approaching the Milky Way at approximately 100 to 140 kilometres per second.Since it is the nearest spiral galaxy to us, astronomers use the Andromeda Galaxy to understand the origin and evolution of such galaxies. ![]() Identity the disk, bulge, halo, and spiral arms, and indicate the galaxy's approximate dimensions., What are the Large and Small Magellanic Clouds and the Sagittarius and Canis Major Dwarfs, Describe the basic characteristics of stars' orbits in the bulge. The Milky May is thought to contain more dark matter, which could make it much more massive. Study with Quizlet and memorize flashcards containing terms like Draw simple sketches of our galaxy as it would appear face-on and edge-on. While Andromeda is the largest galaxy in the Local Cluster it may not be the most massive. ![]()
