The 12 most prominent objects in the universe



DGSAT I is an ultra-diffuse galaxy (UDG) which means it is as large as a galaxy like the Milky Way, but its stars are so thin that it is almost invisible. But since the researchers saw the ghostly DGSAT 1 in 2016, they noticed that it was all alone, quite unlike other UDGs, which are typically found in clusters. Its characteristics suggest that the weak object formed in a very different era in the universe, back just one billion or so years after the Big Bang, making DGSAT 1 a living fossil.
