The powerful James Webb space telescope, which already amazed us in the first months of its scientific observations has taken a new image, which is its largest image of galaxies.
After the scientists analyzed the image, new discoveries were made public.
Webb took a very clear image, compared to other telescopes, thus allowing scientists to see deeper into the Universe and thus make new discoveries. Some of these were announced today by the astrophysicist Rebecca Larson on Twitter, being published on the CEERS website, here.
The collected images as well as the data were made with the help of the NIRCam and MIRI imaging instruments of the telescope.
According to the article written by CEERS, some of the new discoveries are the following (can also be seen in the image below):
- A spiral galaxy at a redshift of z = 0.16. The resolution of the JWST imaging reveals a large number of blue star-forming clumps and star clusters.
- A chance alignment of a bright galaxy at a redshift z = 1.05 with several smaller galaxies forming an arc in the sky when viewed from JWST.
- An interacting system of galaxies at z = 1.4, dubbed the "Space Kraken" by the CEERS team.
- Two interacting spiral galaxies at z = 0.7. The arrow points to a supernova discovered with these JWST images.
- Another spiral galaxy, also at z = 0.7, again highlights JWST's ability to resolve small-scale features even for modestly distant galaxies.
- A chance alignment of a z = 0.63 galaxy with a tidal tail and a grouping of red galaxies at z = 1.85
A galaxy that is very close to the beginning of the Universe was also discovered. This was called Maisie's galaxy in honor of project head Steven Finkelstein's daughter and it could be only 400 million years after the Big Bang, meaning it could be one of the oldest galaxies ever observed by mankind, having over 13.4 billion years.
New discoveries from James Webb are also expected soon and we hope that they will also lead to new worlds, discoveries, and a better understanding of the Universe by us, humans.
