Observing one of the biggest cosmic collisions ever seen by Ana Maria Ciobanu

Nasa's Spitzer and Chandra space telescopes along with ground-based observatories offered the chance to a US team of astronomers of observing one of the biggest cosmic collisions ever seen; Four gigantic galaxies have crashed into one another and are expected to eventually merge into a single huge galaxy- ten times as massive as our Milky Way. This is a very important event for us all because it gives us a closer look at how the most massive galaxies in the Universe were formed and are formed. "It's the first one that I know about. So far, nobody has written to me to say they've found another four-way merger," Kenneth Rines, of the Harvard-Smithsonian Center for Astrophysics, in Cambridge, USA, declared. Kenneth Rines compared the collision to "four sand trucks smashing together, flinging sand everywhere". The stars studied from the merger so far, seem to have formed within the first three billion years after the Big Bang. Who knows what the next years will bring us? We're beginning to see light where there was only dark five years ago so our Universe understanding possibilities are expanding.
