Galaxies from the early universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the universe, according to new research published today.
Using the James Webb Space Telescope , an international team of researchers including those at The University of Manchester and University of Victoria in Canada discovered thatThese galaxies go far back in the universe's history with many of these galaxies forming 10 billion years ago or longer.
However, astronomers previously considered that these types of galaxies were too fragile to exist in the early universe when galaxy mergers were more common, destroying what we thought was their delicate shapes., finds that these disk galaxies are 10 times more common than what astronomers believed based on previous observations with the Hubble Space Telescope.
The research completely overturns the existing understanding of how scientists think our universe evolves, and the scientists say new ideas need to be considered. It was once thought that disk galaxies such as the Milky Way were relatively rare through cosmic history, and that they only formed after the universe was already middle aged.

Astronomers discover newborn galaxies with the James Webb Space TelescopeWith the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed.

James Webb Space Telescope and ALMA capture the core of the most distant galaxy protoclusterThe study of how individual stars are born and die in galaxies, how new stars are born from remnants of old stars, and how galaxies themselves grow are important themes in astronomy, as they provide insight into our roots in the universe. Galaxy clusters, one of the largest structures in the universe, are the assembly of more than 100 galaxies which are bound together through mutual gravitational force.

Tag team of the James Webb Space Telescope and ALMA captures the core of the most distant galaxy protoclusterAn international research team has used the James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array to observe the most distant galaxy protocluster to date, 13.14 billion light-years away. The team has successfully captured the 'core region' of the galaxy protocluster, which corresponds to a metropolitan area with a particularly high number density of galaxies. The team has revealed that many galaxies are concentrated in a small area and that the growth of galaxies is accelerated. Furthermore, the team used simulations to predict the future of the metropolitan area and found that the region will merge into one larger galaxy within tens of millions of years. These results are expected to provide important clues regarding the birth and growth of galaxies.
