The difficulty with the first approach is that a lot of chemical and dynamical evolution has taken place since the formation of galaxies, and these processes tend to wipe out memories of time past. We are then led to studying the oldest stars in our own Galaxy, or trying to search for ...
Scientists wrote in a study that the groups might be the remains of two galaxies that united with the early pieces of the Milky Way 12 billion years ago. They say the discovery offers new information about how our galaxy formed. The Milky Way Galaxy is made up of hundreds of billions of...
Most galaxies haveblack holesat their centers that can produce a tremendous amount of energy, which astronomers can see over great distances. In some cases, a galaxy’s central black hole isextremely largeor active, even in relatively small galaxies. Material circling the black hole may be accel...

Though the researchers found a way that the stars near ourgalaxy's central black hole could have formed, the simulation is notproof that this is what happened. "As satisfying as the new results are, the case fordisk fragmentation as the origin for the disk stars remains unproven,"wrote astro...
