Computer simulation: when 2 galaxies collide... | Jamie Janover

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 and the Andromeda Galaxy. The stars involved are sufficiently far apart that it is improbable that any of them will individually 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 elliptica

This celestial drama, known as the Andromeda-Milky Way collision, is a cosmic dance on an astronomical scale. Over the course of billions of years, these colossal galaxies have been hurtling toward each other through the vastness of space. As they draw closer, gravitational forces will dramatically alter the structure of both galaxies, leading to the birth of new stars and the reconfiguration of cosmic landscapes. The collision promises a breathtaking display of celestial fireworks, with stars a
