The biggest image taken by the telescope so far was just released by a team of scientists. The image is a mosaic of 690 individual frames taken with the telescope and it covers an area of sky eight times larger than the First Deep Field image. Many never seen before are included in the full of early galaxies. The team may have taken a picture of one of the most distant stars.
The scientists said the mosaic is from a patch of sky near the handle of the Big Dipper. The images were taken as part of the first observations of the CEERS team, which is trying to demonstrate that the telescope can be used efficiently for extragalactic surveys.
Rebecca said that this is just the first of their observations. Our data has led to new discoveries and an abundance of never-before-seen galaxies, and we are less than half way through our full survey.
The high-resolution images, available here, should be used to zoom in and explore, according to the author. It doesn't really work to look at the images on small screens like a phone because of the high resolutionversions.
The number of stars we have captured is awe-inspiring. "I said so," she said.
There are a few galaxies of note shown in the mosaic in the middle of the picture. The first spiral galaxy is at a red shift. There is a large number of clumps and clusters of stars.
TBT to one late night when I decided this galaxy on the left (an elliptical galaxy at redshift z=1.05) looked like Pacman and proceeded to overlay the little yellow dude and laughed so hard we all decided it was time to go home. So Pacman (minus Pacman): https://t.co/ZU8XFjQE4A pic.twitter.com/6jPWmDF2DW

There is an interacting system of galaxies at a redshift of 1.4 and two spiral galaxies at a redshift of 0.7. The arrow points to something that is most likely the first supernovae discovered using the JWST images.
The other inset shows a stunning spiral galaxy, which the team says highlights the ability to resolve smallscale features even for modestly distant galaxies, as well as a chance alignment of a galaxy with a tidal tail and group of red galaxies.
Scientists in the CEERS Collaboration have found an object that may be one of the earliest galaxies ever seen. The team put out a paper on the find. That redshift has never been seen before, and would be older than SMACS-0723, which was imaged earlier. The universe is 300 million years old. It could have formed in less than 300 million years after the big bang. The first stars to turn on as hydrogen was ionized allowed the first light to shine through the Universe.
