Summary: Astronomers have found a well formed spiral galaxy just 3 billion years
after the big bang. It is extremely rare for a well formed spiral to
appear this early due to how chaotic the universe still was at this
point. It was helped along by a small dwarf galaxy orbiting it; this
added an extra gravitational pull to form the spiral.
