A light year is the distance light travels in a year . about 6 million, million miles ( 5.879 1012 miles if you understand that method of writing large numbers.) The echo of the pulse return 14.3 us after it was sent out. Infrared light has a lower frequency than visible light. The Andromeda Galaxy, which appears as a milky blur to the naked eye, is one of not many galaxies that can be visible to the naked eye. The nearest large galaxy is the spiral galaxy Andromeda. The Andromeda Galaxy is a staggering 23 billion billion km away. Our Milky Way measures around 100,000 light-years or 30 kiloparsecs. This is a list of known galaxies within 3.8 megaparsecs (12 million light-years) of the Solar System, in ascending order of heliocentric distance, or the distance to the Sun. M31 is so distant it takes about two million years for light to reach us from there. The other galaxies are far enough away from us that we cannot see individual stars in themthey look like fuzzy patches of light on the sky, or even just bright spots like stars. How far away is the airplane? Due to its relative size and proximity to the Milky Way, Andromeda can actually be observed with the naked eye in the night sky. Now it is just a unit conversion problem. What will happen when our galaxy collides with Andromeda? The result of the collision between Andromeda and the Milky Way will be a new, larger galaxy, but rather than being a spiral like its forebears, this new system ends up as a giant elliptical. The pair will end up forming a binary at the heart of the new, larger galaxy. The Andromeda Galaxy's dark dust lanes are a sight to behold. The 2nd name of the galaxy is M31. M31 is the closest major galaxy to the Milky Way and was often How far from the Milky Way Galaxy would the Andromeda Galaxy be on this scale? the emission from the gas in this part of the galaxy is blueshifted relative to the average recession velocity of the galaxy). However, RE astronomers believe the Andromeda Galaxy (M31) to be around 43000 light years across. How far away is the Andromeda Galaxy? Our galaxy, the Milky Way, has collided with another galaxy, called Andromeda. In comparison, the Andromeda galaxy has a diameter of about 220,000 light-years; thus, it is more than twice as large as the Milky Way. As Andromeda moves through the universe, it carries 14 dwarf galaxies, including M32, M110, and M33 (triangular galaxies). Today, we see it as it was 2.5 million years ago. Astronomers no longer thought our galaxy was the entire universe. Here are their distances from us: Large Magellanic Cloud - 179 thousand light years away Small Magellanic Cloud - 210 thousand light-years away Andromeda Galaxy - 2.9 million light-years away One If this is accurate (there is no basis for these numbers provided), then the distance across can be derived using basic trigonometry. To the eye, the galaxy looks like a fuzzy patch. Although the two galaxies are passing through each other at a million miles an hour, the whole process will take many millions of years to complete. Think of space like a balloon that is slowly being inflated, Every point of that balloon is moving away from every other point. Andromeda galaxy is one of them. Through early telescopes, Andromeda was seen as a fuzzy spot in the sky and was assumed to be a nebula of gas lying within the Milky Way. The fastest thing ever built by humans was a Helios probe which reached 70 km/s by using the Sun as a gravitational slingshot. The Andromeda Galaxy (aka Messier 31)has been estimated to be somewhere around 2.5 million lightyears away from us here on Earth. No scale was specified. These spheres are being held above the Earth by DE. The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, and formerly known as the Andromeda Nebula, is a barred spiral galaxy located 2.5 million light-years (770 kiloparsecs) from Earth and the Milky Way's closest big galaxy. The nearest galaxy is the Andromeda galaxy at about 2.5 million light years. But even then, Andromeda was still assumed to be a local nebula. The nearest galaxies to us are the two irregular galaxies called the Large Magellanic Cloud and the Small Magellanic Cloud. The Andromeda nebula was really the Andromeda galaxy.This discovery implied that the other, even fainter, spirals were probably also galaxies even farther away.Hubble published his work in 1929 and changed forever our view of the universe. It turns out that the SW side (lower-right in the picture below) of the galaxy is moving towards us (i.e. IC 1101, which is about 50 times the size of the Milky Way and 2,000 times more massive, is the largest known galaxy. It's around 2,480,000 light-years away from Earth. This galaxy is our neighbor And enemy galaxy. However, if the Earth was one inch, the Andromeda Galaxy would be 29,300,000,000 miles away. In 1887, Isaac Roberts took the first photograph of Andromeda, which revealed its spiral structure. IT MIGHT be our nearest galactic neighbour, but we have never known exactly how far away the Andromeda galaxy is, until now. In fact, the Andromeda Galaxy itself can be found in the constellation Andromeda. (For comparison, our galaxy is 100,000 light years across.) The Andromeda galaxy and 2 satellite galaxies as seen through a powerful telescope. Andromeda is 2.5 million light years away, which is km. Credit: Brian Cummins, Virginia, USA, November 2019. Here is an image of the Andromeda Galaxy as viewed from Earth. However, there are also a multitude of smaller galaxies, called dwarf galaxies, The Andromeda galaxy is the closest big galaxy to our Milky Way. At 2.5 million light-years, it's the most distant thing you can see with the eye alone. Hubble observed Cepheid variables in the Andromeda Galaxy and obtained their luminosities using Leavitt's law. Due to its relative size and proximity to the Milky Way, Andromeda can actually be observed with the naked eye in the night sky. So the nearest galaxy is roughly 15 000 000 000 000 000 000 miles ( 15 1018 miles) The several distinct stars that surround Andromeda's image are actually stars in our Galaxy that are well in front of the background object. The Andromeda Galaxy (aka Messier 31) has been estimated to be somewhere around 2.5 million lightyears away from us here on Earth. The Andromeda Galaxy, M31, photographed by Stephen Rahn, Macon, GA, on Oct. 18, 2020. A radar pulse is sent out and reflects off an airplane. Though this galaxy is quite big (about 10,000 light years across), it will likely be disrupted by the tidal forces from the Milky Way Galaxy. The Andromeda Galaxy is one of the few visible to the unaided eye, appearing as a milky blur. Andromeda is frequently referred to as M31 since it is the 31st object on Messier's list of diffuse sky objects. It spans around 5.5 million light-years. Answer: In fact, we can measure very accurately which parts of M31 are moving towards or away from us. The Andromeda Galaxy, also known as "M31", is a spiral galaxy located 2.2 million light-years away from Earth, facing the constellation Andromeda, as shown in the figure below. The SagDEG is on the other side of the Milky Way from the Sun, about 70,000 light years away. This is due to the inflation of space. (ans: 2.15 km) 10. The Andromeda Galaxy, also known as M31, is a spiral galaxy situated at a distance of 2.5 million light-years from Earth, or (758kpc.) Q:The Andromeda Galaxy is moving toward the Milky Way from 2.5 million light-years away. He also said that this galaxy is far away from the milky way galaxy about 18000 light-years that were a wrong observation. Confusingly that is pretty much the same estimate on some websites for when Andromeda and the Milky Way will collide. It is located about Logged. Using more standard large-scale space units, its around 2.5 million lightyears away. But its an island of stars in space, much like our Milky Way . (ans: 1.89 x 1022m) 9. How far away is the Andromeda Galaxy? A previous program by Hubble, called the Hubble Cosmic Origins Spectrograph (COS)-Halos program, observed 44 galaxies far away and saw halos. This is the big giant galaxy from 60+ galaxies in the local group of galaxies. Today we know that Andromeda galaxy to be about 2.2 million light years away. Compare this to the radius of the Milky Way, about 50,000 light years, and you will see how phenomenal was his discovery. Answered by: Robert Mahoney, M.S., President, Magellica Inc. The Andromeda galaxy is a giant spiral galaxy located only 2.5 million light-years away, making it visible at night to the naked eye. Suppose that galaxy B is twice as far from Earth as galaxy A. Hubble's law predicts that galaxy B will be moving away from Earth with approximately _____. Introduction: The Andromeda Galaxy is also known as M31 and is a spiral galaxy and the closest neighboring galaxy to our Milky Way. Answer (1 of 2): As you noted, almost every galaxy in the universe is moving away from us. As Andromeda moves through the universe it is bringing along 14 dwarf galaxies, including M32, M110, and M33 (Triangulum Galaxy) Its one of the few galaxies that we can see from Earth, and thats saying a lot since it is 2.5 million light-years With the advent of modern telescopes and science, the Andromeda Galaxy is now known to be some 2.5 million light years from us. List of nearest galaxies. The Andromeda Galaxy, also known as Messier 31 or M31, is a spiral galaxy located The Andromeda Galaxy is 2 million light years from the Milky Way. The distance of Andromeda galaxy from Earth is 2.537 million light years and hence it will take that many years for light to travel to Andromeda galaxy. How long would it take to reach the next galaxy? If we consider galaxies comparable in size to the Milky Way (our galaxy), the nearest galaxy is Andromeda located about 2.5 million light years away.
