We knew that the James Webb Space Telescope, or JWST, would bring surprises, and it certainly

has delivered thus far.

The latest revelation, the first galaxies in our universe, might have formed much earlier than we thought. This finding comes from

announcements by astronomers at the 241st meeting of the American Astronomical Society in Seattle this

past week. The JWST is much more sensitive than the Hubble Space Telescope, so it can,

essentially, see much further back in time.

For one study, currently undergoing peer review and presented at the conference,

focusing on JWST's views of galaxies from when the universe was about 500 million to 2 billion years old,

quoting Sky and Telescope, 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. Then again,

those previous studies also had a hard time classifying the most distant ones, which looked like

little more than smudges. That's where the JWST comes in. The longer wavelengths that JWST detects enable it to see farther back in time.
