Milky Way Galaxy Doomed

Will our Milky Way Galaxy collide one day with its larger neighbor, the Andromeda Galaxy? Most likely, yes. Careful plotting of slight displacements of M31′s stars relative to background galaxies on recent Hubble Space Telescope images indicate that the center of M31 could be on a direct collision course with the center of our home galaxy. Still, the errors in sideways velocity appear sufficiently large to admit a good chance that the central parts of the two galaxies will miss, slightly, but will become close enough for their outer halos to become gravitationally entangled. Once that happens, the two galaxies will become bound, dance around, and eventually merge to become one large elliptical galaxy — over the next few billion years.

Pictured above is an artist’s illustration of the sky of a world in the distant future when the central parts of each galaxy begin to destroy each other. The exact future of our Milky Way and the entire surrounding Local Group of Galaxies is likely to remain an active topic of research for years to come.

    Not really. Blogs are usually meant to be the voice of the author, not a forum per se. I’ve chosen to create this blog to represent what i love in life. I’m not trying to comment on politics or policies or talk about specific issues very often. I prefer to keep this blog a place where people come to hear my views, and see beautiful images to reflect my values about beauty, inspiration and love.
