The andromeda–milky way collision is a galactic collision predicted to occur in about 4 billion years between two galaxies in the local group—the milky way (which contains the solar system. The andromeda galaxy is the closest spiral galaxy to our milky way and the most distant thing you can see with your eye alone find it in your night sky. From hubblecast scientists have been using hubble observations to predict the future of the andromeda galaxy and the milky way, and how the collision will l. Four billion years from now, our galaxy, the milky way, will collide with our large spiraled neighbor, andromeda the galaxies as we know them will not survive in fact, our solar system is.
The milky way's nearest neighbor is headed directly towards our galaxy, sooner than astronomers thought.
Our galaxy, the milky way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and about six times as much and, often, galaxies collide.
Sometime in the next 5 billion years, our milky way galaxy will smash into the andromeda galaxy this galaxy is our nearest neighbour, a mere 25 million light years away—practically. The andromeda galaxy (/ æ n ˈ d r ɒ m ɪ d ə /), named after the mythological princess andromeda, also known as messier 31, m31, or ngc 224, is a spiral galaxy approximately 780 kiloparsecs. The milky way is destined to get a major makeover during an encounter with the andromeda galaxy, predicted to happen 4 billion years from now.
This is one of series of photo illustrations showing the predicted merger between our milky way galaxy and the neighboring andromeda galaxy, as it will unfold over the next several billion. The andromeda galaxy (m31) is the closest large galaxy to the milky way and is one of a few galaxies that can be seen unaided from the earth in approximately 45 billion years the andromeda. Image to left: many years from now, our descendants may see the mixing of the galaxies credit: nasa our galaxy, the milky way, has collided with another galaxy, called andromeda.
Astronomers used to believe that the andromeda galaxy, our nearest galactic neighbor, was three times the size of the milky way not anymore.
