However, the discovery of a massive rotating disk galaxy, much like our own Milky Way, when the Universe was just 1.5 billion years old calls these models into question.

But now, astronomers have spotted an ancient galaxy that seems to do just that. Known as DLA0817g, or the Wolfe Disk, it looks like a modern disk galaxy, rotating at about 272 km/s (170 mi/s).

It’s known as Galaxy DLA0817g, but astronomers nicknamed it the Wolfe Disk after late astronomer Arthur M. Wolfe, former doctoral advisor to three of the study’s four authors.

Galaxy DLA0817g, dubbed the "Wolfe Disk" after the late astronomer Arthur M. Wolfe, was discovered using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.

A massive, rotating disk galaxy that first formed just 1.5 billion years after the Big Bang, could upend our understanding of galaxy formation, scientists suggest in a new study.

Astronomers say that a massive disk galaxy from the ancient universe, known as the "Wolfe Disk," should never have existed. "Most galaxies that we find early in the universe look like train wrecks ...

Hubble observed massive stars in ultraviolet light. “ The star formation rate in the Wolfe Disk is at least ten times higher than in our own galaxy,” Prochaska said. “It must be one of the most ...
