Pingie: HTTP:: The Peculiar Nature of 11 Billion Year Old Galaxies

HTTP:: The Peculiar Nature of 11 Billion Year Old Galaxies
--------
Scientists gained the ability to peer way back into the Universe's history some time ago, but some of the discoveries they made were not exactly in tune with some of the theories that were developed to explain astronomical phenomena today. In a recent such find, distant stars, estimated to be about 11 billion light-years away, in the early Universe, were discovered to travel at about 1 million miles per hour, about twice faster than our own Sun moves through the Milky Way. The study is so important because it adds more substance to previous finds, which showed a peculiar trend among early galaxies. According to astronomers, the youngest and most massive new galaxies that were formed within 2 to 3 billion years after the Big Bang were very heavy, yet extremely compact and hyperactive. The reason why these galaxies were on average about five times smaller than the same type as today has thus far eluded scientific understanding. “A lot of people were thinking we had overesti!
mated these masses in the past. But this confirms they are extremely massive for their size. These galaxies are indeed as bizarre as we thought they were,” says of the new study its leader, Pieter van Dokkum, who is an astronomer at the Yale University. For the new investigation, his team focused on a galaxy designated as...
