Galaxy of the dating
As the Milky Way was growing, taking shape, and minding its own business around 10 billion years ago, it suffered a massive head-on collision with another, smaller galaxy.That cosmic cataclysm changed the Milky Way’s structure forever, shaping the thick spirals that spin out from the supermassive black hole at the galaxy’s core.“You’re basically surrounded by that debris now.” He and his team found a large number of stars that aren’t moving in step with the galaxy’s rotation.Instead, they move in radial orbits, streaming toward or away from the center of the galaxy.🙊 Virtual pets Get a virtual pet and it won't make you bored. 🎮 Games Play Trivia, Cannons & Barrels, Mafia and other popular games.

“This is a big step forward,” said Elena D’Onghia, an astrophysicist at the University of Wisconsin who is unaffiliated with the new research.They’re the scions of stars from a long-ago galaxy that smacked into the Milky Way, their orbits still reflecting the odd trajectory of that cosmic agitator.“If you throw a stone in a pond, those ripples last for awhile.In an analogous way, if you shake the Milky Way disk, even billions of years ago, it can take awhile for that response to settle down,” said Johnston.Belokurov’s group also modeled different collision scenarios, as well as a possible quieter history without significant collisions.
