![]() ![]() Previous studies, such as those done using the Hubble Space Telescope, had suggested that as we look back toward a younger universe, the stable rotating disks of today give way to more chaotic shapes, representative of the violent mergers that built up the first galaxies. Speaking as part of the Cosmic Evolution Early Release Science (CEERS) collaboration, Jeyhan Kartaltepe (Rochester Institute of Technology) reported Webb’s views of galaxies when the universe was between 500 million years and 2 billion years old. Levay Cutout images: NASA / STScI / CEERS / TACC / S. This is one of the first images obtained by the Cosmic Evolution Early Release Science Survey (CEERS) collaboration and contains several examples of high-redshift galaxies with various morphologies, including a surprisingly high fraction of disks. Young But Mature This image - a mosaic of 690 individual frames taken with Webb's Near Infrared Camera (NIRCam) - covers a patch of sky near the handle of the Big Dipper. ![]() The results may end up changing what we know about how the first galaxies formed. Evidence is building that the first galaxies formed earlier than expected, astronomers announced at the 241st meeting of the American Astronomical Society in Seattle, Washington.Īs the James Webb Space Telescope views swaths of sky spotted with distant galaxies, multiple teams have found that the earliest stellar metropolises are more mature and more numerous than expected. ![]()
