According to the Big Bang theory, galaxies in the early universe were not well defined. For the first several billion years of stellar evolution, most galaxies were in their infant stages and they looked irregular and unorganized. The last thing astronomers would expect to see in the young universe would be a well-organized spiral galaxy.
Yet, that is exactly what they found.
According to images obtained using the Hubble Space Telescope, astronomers from the University of Toronto and UCLA have reported finding the spiral galaxy in a section of the universe that would place it within several billion years of the Big Bang or about 10.7 billion years ago from our current time frame.
