Astronomers have used Webb to discover some of the earliest galaxies with a feature called stellar bars, making them similar to our Milky Way.
As the James Webb Space Telescope looks back at some of the earliest galaxies, it is helping us learn not only about galaxies very different from our own but also about how galaxies similar to the Milky Way were first formed. Recently astronomers announced they have used Webb to discover some of the earliest galaxies with a feature called stellar bars, making them similar to our barred spiral galaxy seen today.
An earlier image of galaxy EGS23205 taken by Hubble was smudgy and hard to see any structure in, but the new image from Webb shows a bright bar structure much more clearly. Another galaxy, EGS-24268, was also imaged by Webb and is thought to be from 11 billion years ago. Finding these structures in very early galaxies is intriguing as it suggests astronomers will have to adjust their models of how galaxies evolve.
