Oldest galaxy pile-up was found
Recently, a team of scientist managed to discover what seems to be one of the biggest galactic collisions t hat has ever
been seen. Being named LBG-2377, this cluster is situated at more than 11.4 billion light years away. The team used the volcano-top Keck Telescope in Hawaii in order to capture the image of galaxies in the act of coming together at about two billion years after the Big Bang. This discovery was part of a larger survey of distant galaxies, and Dr Jeff Cooke, a researcher at the University of California at Irvine stated that this particular cluster showed up as a particularly bright one. This means that the cluster must be at least 10 times bigger than the Milky Way in order to be so bright at such a distance.
The interesting thing is that several galactic signals are being emitted, and hundreds of young stars are emerging from the collision. This is due to the fact that the collision is very violent and destructive, this many new stars are born, so this is why the cluster has become so bright.
Scientists believe that all galaxies cluster in the same way: they gather into growing groups over time and sometimes merge, forming giant galaxies, some of which may contain over 1000 smaller galaxies. For example, our own galaxy is part of a cluster know as the Local Group, which contains about 35 galaxies, all of which are quite small.
