Collisions of Milky Way and Andromeda

After a few billion years Milky Way galaxy will collide with the Andromeda galaxy.It would mean as destruc tion and also creation, because the galaxies will merge into one but also cosmic clouds of gas and dust will rout together, a result of which will be created a new stars.Because of that astronomers for better understand this process have assembled an atlas of several galactic “train wrecks.”The new images join observations from NASA’s Spitzer Space Telescope, which observes infrared light, and NASA’s Galaxy Evolution Explorer spacecraft, which observes ultraviolet light. So analyzing information from different parts of the light spectrum give opportunity scientists to more learn about collisions of galaxsies.
