Images collected from NASA’s Spitzer Space Telescope are shedding light on the dramatic conditions that arise when two galaxies collide. Due to the strong gravity resulting from the large mass of a galaxy, galaxies are drawn together and eventually collide. Sometimes this results in one of the galaxies being annihilated, as scientists believe will happen when the Large Magellanic Cloud collides with our Milky Way in two billion years’ time. But at other times, the two galaxies merge together to create one huge galaxy.
Death or Glory? It’s going to take billions of years to decide.
