Astronomers have created a satin collision of galaxies, including our own, which will take place in five billion years. Clash of the Milky Way (our parent galaxy of the Earth) and the Andromeda galaxy, is projected to occur in 3-5 billion years. This merging of galaxies, according to experts, is a clear example of "the formation, growth and evolution of galaxies." Atlas of galaxy collisions has been created on the basis of information obtained Spitzer Space Telescope and Galex.
Galex (Galaxy Evolution Explorer or Explorer Evolution of Galaxies) is monitoring in the ultraviolet light, allowing you to explore the radiation of young hot zvezd.Spittser monitors infrared radiation of warm dust and the stellar surface. Some galaxies like NGC 935 and IC 1801 have already started their galactic collision sliyanie.No the Milky Way and Andromeda, is expected no sooner than a few billion let.Stolknovenie lead to the birth of new stars from crashing into each other cosmic clouds of gas and dust . Lauranna Lantz Smistonievskogo of Harvard Center for Astrophysics, said: "This atlas - the first step to reconstruct the history of the formation, growth and evolution of galaxies." "We are working with the theorists to give a realistic model."
"But the real test of our understanding will happen in five billion years, when there will be a clash Milky Way." Clash of galaxies leads to the formation of new stars, but in each case, the number of new stars variruetsya.Lents and her colleagues are trying to find regularities and differences in physical processes which depend on the formation of new stars that will create a computer model of such collisions.
