Will the Milky Way and Andromeda merge?
The Andromeda galaxy is currently racing toward our Milky Way at a speed of about 70 miles (113 km) per second. With this in mind, our merger will occur five billion years from now.
How long will it take for Andromeda and the Milky Way to merge?
around 5 billion years
Taking also into account the sun’s motion, Andromeda’s tangential or sideways velocity with respect to the Milky Way was found to be much smaller than the speed of approach (consistent with zero given the uncertainty) and therefore it will eventually merge with the Milky Way in around 5 billion years.
What will happen if Milky Way and Andromeda collide?
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 authors of the paper in question have named this new galaxy ‘Milkdromeda’.
Will humanity ever leave the Milky Way?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
How long until the Milky Way dies?
Scientists suppose that in about four billion years the star formation will stop, which is almost just a blink of an eye in the life cycle of the universe. The Milky Way is dying and we don’t know why.
Which is bigger Milky Way or Andromeda Galaxy?
The reason the collision is happening a few billion years ahead of schedule is that the Andromeda Galaxy is much bigger than it appears. The galaxy’s bright, starry disk is about 120,000 light years in diameter, making it slightly larger than the Milky Way.
When will Andromeda collide with Milky Way?
The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group —the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
What is the distance between Milky Way and Andromeda Galaxy?
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.
What will happen when our galaxy collides with Andromeda?
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.
