M31 - Andromeda Galaxy . Andromeda is a spiral galaxy of similar size, so we can think of it as a second CD. At 140,000 light years across, it’s 40% bigger than our 100,000 light year diameter Milky Way. Andromeda can be difficult to observe in detail because of its large size in the sky. The nearby galaxy Andromeda will eventually (in about 4 to 5 billion years) merge with our own galaxy, the Milky Way. Wiki User . Putting the size to 500,000 light years across. In fact, if you want to observe Andromeda in its entirety, a low-power, wide-angle eyepiece is best. Specifically, the new study shows that the Andromeda galaxy is 800 billion times heavier than the sun, which is roughly the same weight as the Milky Way, according to the statement. The full Andromeda Galaxy, M31, is at least 3.5 degrees wide, and perhaps as wide as 5 degrees. Both Andromeda and the … Andromeda is 2.5 million light years away from us, or about 25 Milky Way diameters.

In the wreckage of the galaxy, Andromeda and her crew soon discovered the Magog

Our understanding of the size of the Andromeda galaxy has grown bigger in recent years.

Only the much smaller core is visible without long-exposure photography. The Andromeda Galaxy (IPA: / æ n ˈ d r ɒ m ɪ d ə /), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a spiral galaxyAndromeda Galaxy (IPA: / æ n ˈ d r ɒ m ɪ d ə /), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a spiral galaxy Andromeda is the closest large galaxy to us. The Andromeda Galaxy is located about 2,480,000 light-years from Earth, and its diameter is approximately 200,000 light-years. Andromeda Galaxy, great spiral galaxy in the constellation Andromeda, the nearest large galaxy. The Andromeda Galaxy (Cataloged Messier 31), is a spiral galaxy located about 2.5 million light-years from Earth.

A new study published February 15 in the Monthly Notices of the Royal Astronomical Society finds that the Andromeda galaxy is actually around the same size as our own galaxy… Messier 31 or M31 (also designated NGC 224) is a spiral galaxy in the constellation Andromeda. The Andromeda Galaxy is a spiral galaxy, just like our own galaxy (the Milky Way). This is size as in, at 10-20x the diameter, which means 3-4 times the area, or in reality slightly less because the Andromeda is seen as an eclipse not a circle, unlike the moon. It is one of the few visible to the unaided eye, appearing as a milky blur. In fact, if you want to observe Andromeda in its entirety, a low-power, wide-angle eyepiece is best. You would need more than … Imagine the Milky Way galaxy as a music CD (the thickness compared to its diameter is about right). It has an apparent visual magnitude of 3.4 and its angular diameter is 178x63 arc-minutes. Angular diameter or size Relative size Andromeda Galaxy: 3°10′ by 1° About six times the size of the Sun or the Moon. It sits approximately 2.5 million light-years away NASA Galaxy Evolution Explorer/JPL-Caltech/NASA . Angular diameter or size Relative size Andromeda Galaxy: 3°10′ by 1° About six times the … Recent observations showed a "halo" of Stars around the Galaxy - a bit like suburbs to a city.

You can actually get some fairly good views with a very good pair of large lens binoculars. It has an apparent visual magnitude of … The Andromeda Galaxy is a spiral galaxy, just like our own galaxy (the Milky Way). Here’s a picture to scale: She and her crew found that the entire galaxy had been stripped bare and destroyed, with nothing left but a gigantic cloud of gas and other debris. But on the scale of galaxies, they are quite close together.
