Collision between Via Laáctea and Andromeda
When galaxies collide
By Mariano Ribas
The word is out: now, our dear Milky Way is approaching at full speed to its big brother, the giant Andromeda galaxy. And a brand-new research reveals the clash is inevitable. Anyway, not to run out the cries announcing the end of the world because intergalactic distances are so enormous that the sensational new meeting will occur within billions of years. Moreover, if by entoia.
Birth Via Andromeda It appears that the Milky Way and Andromeda are approaching the tune of 500,000 km / hour. But as they are nearly 3 million light years away, it will rub in just 3 billion years. Over the millennia, the two galaxies begin to coalesce (sounds ugly, but that's the right word). And contrary to what one might think, would be transferred to each other, with virtually none of the stars of a crash with the other (the distances between stars are so enormous that there is plenty of room for many other transit without problems.) But: have significant intellectualgravitational interaction, which would originate continuous streams of stars that would go from one place to another. Gradually, and after hundreds of millions of years, the two spiral galaxies would lose their initial forms, melting into a monster quite elliptical, which could baptize Via Andromeda, to put some clear name. What would happen to the Sun and our planet? According to Dubinsky, the chances are that our star shot out toward the edges of the new galaxy, or, to its innermost parts. "The earth will continue in its nearly circular orbit around the Sun," says the researcher, because the Sun's gravity will be stronger than the gravitational pull of other stars. " Anyway, at that time, the Sun and beto a star very old, about to die. If humanity still survives, is the right time to pack up, and sent to move. But that's another story. + SOURCE
