An international group of astronomers discovered a fusion of 14 colliding galaxies.
The colossal fusion of 14 colliding galaxies is located 12 billion light-years from the Earth. The light from the confluence began traveling to us 1.4 billion years after the Big Bang, when the age of the universe was only a tenth of its present age. The protocluster, named by scientists SPT2349-56, was formed a billion years after the Big Bang.
Computer modeling of galaxies predicts that over time this cluster will be assembled into one of the most massive structures, and perhaps the most massive known object in the modern universe.
The galactic cluster was first seen as a weak spot of light, using the South Pole telescope and the Herschel observatory. Then astronomers used a set of radio telescopes located in the Chilean Atacama Desert, for more detailed observations.
