Summary

Description
English: This animation depicts the collision between our Milky Way galaxy and the Andromeda galaxy. Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together about 4 billion years from now. Around 6 billion years from now, the two galaxies will merge to form a single galaxy. The video also shows the Triangulum galaxy, which will join in the collision and perhaps later merge with the Andromeda/Milky Way pair.
Français : Simulation de la collision entre Andromède et la Voie Lactée. La simulation s'étend sur environ 6 milliards d'années : 4 milliards d'années avant le contact et 2 milliards d'interactions avant l'unique galaxie finale. La simulation présente également la galaxie du Triangle, qui rejoindra peut-être plus tard le duo Andromède-Voie Lactée fusionné.
