Most Distant Rotating Galaxy REBELS-25 Challenges Cosmic Formation Theories

Astronomers discover a Milky Way-like galaxy from when the Universe was just 700 million years old, questioning current models of galaxy evolution.

REBELS-25 is the most distant rotating disk galaxy ever observed, dating back to 700 million years after the Big Bang.
Current theories suggest galaxies take billions of years to form orderly structures, but REBELS-25 shows a smooth, rotation-dominated structure much earlier.
The discovery was made using the Atacama Large Millimeter/submillimeter Array (ALMA), which provided high-resolution data of the galaxy's structure.
Surprising features like a central elongated bar and potential spiral arms were observed, indicating more advanced development than expected for its age.
Future observations of REBELS-25 could further alter our understanding of early galaxy formation and the evolution of the Universe.
