The image below is an image of the oldest spiral galaxy that scientists say formed 12.4 billion years ago. The old galaxy is named BIS 1335-0417 and the image was taken by the telescope Attacama Grand Millimeter \ millimeters (Alma) in Chile. The image is notable because it shows that spiral galaxies have been formed from 1.4 billion years after the Big Bang. Photographs such as these are essentially looking over time because we see it, more than a billion years ago because of the time limit for joining us.
Astronomer Dr. Kai Noeske says that the photo shows that galaxies began to look like modern galaxies of about 1 billion years earlier than previously supposed. Scientists say that spiral galaxies are forms of more mature galaxies. In the early stages of a galaxy, dark matter brings hot gases together in tufts that create stars. The stars are then found to create larger galaxies that are at the beginning of their lives are Misshapen. Finally, galaxies begin to turn, creating disk-like shapes.
Spiral galaxies occur when these disks begin to be disturbed. Noeske says that on something other than being pretty to watch, spiral arms also compress the gas to become catalysts for the new star formation. Currently, scientists believe that Galaxy training culminated about 3.3 billion years after the Big Bang when most stars present in the universe were formed. It was a surprise that the BIS 1335-0417 already had similar structures to neighboring galaxies well before the active phase of the formation of galaxies. Before discovering BRI 1335-0417, the oldest known galaxy was formed 2.5 billion years after the Big Bang.
This makes BIR 1335-0417 older about 1 billion years. The new conclusions change scientific knowledge on how galaxies have trained and have evolved in what we see today. Astronomers note that while Bi 1335-0417 is the oldest known spiral galaxy, it is not the oldest galaxy ever observed. This title goes to a galaxy called GNZ11 spotted last December 13.4 billion years ago, just 400 million years after the Big Bang.
