Astronomers Have Discovered An Ancient Galaxy Even Older Than Milky Way

Astronomers have discovered a huge rotating galaxy disc and this is known that around 1.5 billion years after the Big Bang it was well ordered, cold and intact even today.

The Wolfe Disk galaxy is the new one that was discovered by the astronomers from the National radio astronomy observatory with the help of Atacama Large Millimeter/submillimeter Array (ALMA).

This university discovered is around 13.8 billion years old and most of the galaxies including Milky Way were formed gradually over the years thereby reaching their current size relatively late.

During the early time, the Milky Way universe and other galaxies were like train wrecks that were undergoing a violent merger for the initial 6 billion years. But then within the formation of the Big Bang – the Wolfe Disk was already well-formed as per the astronomers and they further say that this will be the new view of the early universe.

The discovery of the Wolfe Disk has become a challenge for the formation of many galaxy simulations that predict the massive galaxies at this point in the evolution of the cosmos grew through many mergers of smaller galaxies and hot clumps of gas.

These hot mergers of the galaxies make them difficult to get their order, cold rotating disks as we observe in our present universe right now.
