Discovery of Evolved Galaxy REBELS-25 Challenges Theories

Astronomers have discovered a remarkably evolved galaxy, REBELS-25, dating back to when the universe was merely 700 million years old, challenging current understanding of galaxy formation. Using the Atacama Large Millimeter/submillimeter Array (ALMA), researchers observed the galaxy's orderly structure resembling that of the Milky Way, suggesting that such evolution may occur much faster than previously thought. The finding, reported in the Monthly Notices of the Royal Astronomical Society, indicates that early galaxies might not always be chaotic and disorganized as traditionally believed. The discovery of REBELS-25, with features like a rotating disk and spiral arms, suggests a need to revise theories about how galaxies evolve over cosmic timescales. This breakthrough adds to the complexity of astronomical knowledge about the early universe, where galaxies were thought to be clumpy before becoming well-organized over billions of years. Scientists are keen to conduct further studies to confirm the mature traits of this galaxy and better understand its significance.
