India, July 18 -- Researchers at the Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, have found that some of the earliest known galaxies were already surprisingly well organised less than a billion years after the Big Bang.

Using deep images captured by the National Aeronautics and Space Administration's (NASA) James Webb Space Telescope (JWST), the team discovered that these ancient galaxies obey a fundamental rule of galaxy structure known as the Kormendy relation-a scaling law that links the size of a spheroidal (rounded) galaxy to its surface brightness.

The study was published on July 2 this year in the IOP Science journal.

The finding pushes one of the cornerstones of galaxy evolution much further back in co...
