A Milky Way-like galaxy in the early universe

AUSTIN: Scientists have discovered galaxies in the early universe that are strikingly similar to our own Milky Way galaxy.

The discovery was made by scientists using NASA’s James Webb Space Telescope, capable of peering into the universe’s past.

In an astronomical survey led by Professor Steven Finkelstein of the University of Texas at Austin, Texas, the scientists have discovered galaxies that have ‘stellar bars’. A stellar bar is a long strip of bars that run from the center of galaxies to the edges.
According to the researchers, the galaxies identified date back to a time when our universe was a quarter of its present age.

The discovery of ‘bar galaxies’ like our Milky Way galaxy in the early universe will require an update on the theories of galaxy evolution.

These bands were not clearly visible in early images taken by the Hubble Telescope before the James Webb Space Telescope. A Hubble image of a galaxy called EGS-23205 showed only a single spot. While in the image taken by the James Webb Space Telescope, a beautiful spiral galaxy can be seen with a star belt in the center.

The team identified another ‘bar galaxy’, EGS-24268, which formed 11 billion years ago and is one of the two oldest ‘bar galaxies’ discovered so far.
