In 1959 Franz Kahn and Lodewijk Woltjer suggested that maybe the Andromeda and Milky Way are gravitationally bound, forming a binary galaxy system. They argued that the two galaxies were born together and just moved apart because of the cosmic expansion.Dubinski...
By the time the Milky Way and Andromeda collide, though, much of the gas in both galaxies will have been used up to create stars, so a “starburst” won’t happen. It won’t be a quick merger, though, and the spiral structure of each will be seriously changed. As you can see int...
It is commonly believed that our own Milky Way is on a collision course with the neighbouring Andromeda galaxy. As a result of their merger, predicted in around five billion years, the two large spiral galaxies that define the present Local Group would form a new elliptical galaxy. Here we ...
If the Universe Is Expanding, Why Are the Milky Way and Andromeda Galaxies on a Collision Course? [Video]Eric R. Olson
Collision theory（碰撞理论）指的是化学反应发生的前提是反应物分子之间发生碰撞，且这些碰撞必须满足一定...

“This represents very slim pickings when compared to nearby galaxies of the same size as the Milky Way. For example, our nearest neighbor, the Andromeda galaxy, devoured galaxies weighing nearly 30 times more than those consumed by the Milky Way. ...

In a series of three papers published in The Astrophysical Journal, van der Marel and collaborators discuss the timing and dynamics of the 'imminent' - or at least inevitable - collision between the Milky Way and the neighbouring Andromeda galaxy. The inevitable aspect of this situation has been...
Galactic collisions and mergers are monumentally energetic and dramatic events, but they take place on a very slow timescale. For example, theMilky Wayis on track to collide with its nearest galactic neighbor, theAndromeda Galaxy(M31), but these two galaxies have a good four billion years to ...
