Giant Anomaly of the Early Universe — Most Ancient Spiral Galaxy Discovered

Oldest Spiral Galaxy


Astronomers have discovered the most ancient known spiral galaxy in the Universe. Analyzing data obtained with the Atacama Large Millimeter/submillimeter Array (ALMA), researchers found a galaxy with a spiral dated at only 1.4 billion years after the Big Bang. This is the most ancient galaxy of its kind ever observed. The discovery of a galaxy with a spiral structure at such an early stage is an important clue to solving the classic questions of astronomy: “How and when did spiral galaxies form?”
