Astronomers are still attempting to predict what it will be like when the Andromeda Galaxy and the Milky Way eventually collide. It's be known for a while that an Andromeda-Milky Way collision is inevitable. Measurements of the Doppler shift of the Andromeda Galaxy's spectral lines indicate the...

The Andromeda Galaxy (M31) is the closest large galaxy to theMilky Wayand is one of a few galaxies that can be seen unaided from the Earth. In approximately 4.5 billion years the Andromeda Galaxy and the Milky Way are expected to collide and the result will be a giant elliptical galaxy. ...
When the Milky Way and Andromeda merge in about 4.5 billion years, they will probably form a huge elliptical galaxy. Chances are that oursolar systemwill be relatively unaffected. We might be pulled away from the center of the galaxy, or we might be totally ejected from it. Stars are so ...
Andromeda's "halo" already bumping into Milky Way's ahead of collision Astronomers have mapped out a huge invisible region of the galaxy next door. Hubble has detailed the size and structure of Andromeda's gas halo – and found that it’s already bumping up against that of the Milky Way...

This NASA animation shows how the Milky Way and Andromeda galaxies will collide.
Monte Carlo simulations are used to quantify the uncertainty as a function of sample size.For the Milky Way Galaxy, the satellite sample consists of 26 galaxies with line-of-sight velocities. We find that the mass of the Milky Way within 300 kpc is M300= 0.9 卤 0.3 1012 M assuming ...
The Andromeda Galaxy is the largest in the local group of galaxies to which the Milky Way belongs, and twice its size. It is a spiral galaxy 2.3 million light-years away, and it is the most distant object visible to the naked eye. ...
