Instead, they found that our nearest galactic neighbor is more or less the same mass as the Milky Way — some 800 billion times the mass of the Sun. NASA also agreed that the Sun will likely fling into another part of the galaxy. Astronomers have known for some time that the Milky Way and the Andromeda galaxies will collide on some future date. Andromeda is the largest galaxy in the so-called Local Cluster but the Milky Way is believed to be heavier. When the Milky Way and Andromeda COLLIDE: Stunning simulation reveals the fate of our galaxy in five billion years. By that time, the Sun would have run out of fuel, leading it to expand Venus' orbit. The Milky Way is destined to get a major makeover during the encounter, which is predicted to happen four billion years from now. 1. For decades, astronomers have been saying that our home galaxy, the Milky Way, is destined someday to collide with the … Calling the event a "titanic collision," the United States space agency said that the merger will be happening about four billion years from now. The merger will, however, affect the orbits of the stars, sending them on brand new trajectories. The Andromeda Galaxy is approaching the Milky Way at nearly a quarter million miles per hour. We will use your email address only for sending you newsletters. In 2012, researchers determined that a collision between the Milky Way and the Andromeda Galaxy was sure to happen, based on Hubble data that tracked the motions of Andromeda from 2002 to 2010. Another galaxy Andromeda will collide with our galaxy, what on earth will happen? 5. That is, in approximately 4.5 billion years, the two largest galaxies in the Local Group, the Milky Way and Andromeda (also known as M31), will collide and become one. Our home galaxy is a so-called spiral galaxy with four arms. This galactic collision might be more impactful than you think.See that bright object in the sky? And it’s scheduled to collide, head-on, with the Milky Way in approximately 3.75 billion years. ", "Regardless of the name, it will be the greatest transformative event in the history of the Milky Way.". The galaxies as we know them will not survive.

In this image, representing Earth's night sky in 3.75 billion years, Andromeda (left) fills the field of view and begins to distort the Milky Way with tidal pull. But not to worry. Astronomers have suspected for some time it will eventually collide with our Milky Way. Dr Kafle said the research suggests scientists previously overestimated the … Both the Milky Way and the Andromeda galaxy (M31) are giant spiral galaxies in our local universe. Including the gravitational influence of M33 and the LMC, however, causes a delay of about 1 billion years, and the first collision between the Milky Way and M31 occurs 5.5 billion years from now. Lavender stated that: "There is even a 12 percent chance that the Sun could be completely ejected from Milkomeda, left to spend an eternity drifting alone the intergalactic space," she also said that "We would only be swapping galaxies for a short while, as the merger will eventually bring us back together again.". There is also a small chance the small M33 will each the Milky Way before Andromeda does. Sure it's still billion of years away, but here are some of the top theories from experts March 24, 2017 3:31 a.m. PT Scientists now believe we'll hit Andromeda … Lavender wrote: "Our two galaxies will start ripping chunks out of each other, tidal streams trailing away, their central bars destroyed and their spiral arms twisted this way and that. They will merge into a much larger elliptical body called Milkomeda. If the collision speed is slow, the two galaxies may not have enough energy to separate again, resulting in an eventual merger into a single giant galaxy. On Wednesday, astronomers working with NASA's Swift satellite spotted what looked like massive bursts of radiation in the Milky Way… It is said that in about four billion years, the Andromeda Galaxy will collide with a neighboring galaxy, which is none other than our Milky Way Galaxy, and the phenomenon will cause a makeover in this part of the universe. newspaper archive.
