The galaxy, spotted with ALMA, had been obscured by a huge cloud of dust, making it invisible to other telescopes.
The galaxies formed in the first two billion years after the Big Bang.
It's confirmed: The universe is expanding 9 percent faster than expected.
The discovery alone will not be sufficient to fill this gap, but it is an essential puzzle piece in the understanding of the interactions of fundamental particles.
If correct, the new theory would mean these black holes would all have about the same mass.
Galaxy 12 billion light years away is spewing out stars 1,000 times faster than the Milky Way.
The finding shines new light on our understanding of the cosmos.
Astronomers previously thought these events only occurred around 3 billion years after the Big Bang, but they were happening when the universe was only half that age.
Antimatter and matter should have completely annihilated each other in the Big Bang, leaving nothing but energy.
"Ordinary real time is replaced by imaginary time, which behaves like a fourth direction of space." If you say so, Dr. Hawking.
"Really this was the best option in the world."
The device will search for the origins of the universe.
The galaxies had been invisible to every other instrument that ever looked at them.
A group of scientists in Brazil think the universe began a little differently.
The hyper-luminous galaxies are located 13 billion light years away when the universe was in its infancy.
It belongs to "a class of mythical beasts in astrophysics," and there may be many more waiting to be discovered.
Experiments at CERN still cannot explain how matter formed in the early universe.
We didn't necessarily have to end up in a 3-D world.
Normal matter makes up just five percent of the universe, but we can only see about 2.5 percent of it.
How supermassive black holes formed so quickly after the start of the universe has long baffled scientists.
Supercomputer simulations reveal we are all made up of a bit of extragalactic matter.
