Astronomers taken on the role of cosmic archeologists, using the James Webb Space Telescope (JWST) to excavate over 100 disk galaxies from up to 11 billion years ago. Just like artifacts excavated here on Earth tell the story of the human race, these galaxies could tell the story of our galaxy, the Milky Way.
The aim of this investigation was to discover why galaxies like the Milky Way are constructed of thick disks of stars with embedded thin stellar disks. Each of these disks feature its own distinct stellar population with its own movement.
