JWST4Y JacA dwarf galaxy. It is illuminated by a strong, cool light radiating from its core, a bar-shaped area at the centre, and filled with a huge number of visible stars that appear as tiny glowing points. Faint wisps and clouds of dust wind around and through the galaxy’s core. Some are lit up by star-forming regions inside them. Many small, distant galaxies can be seen through and around the dwarf galaxy.
The James Webb Space Telescope observed the "starburst" galaxy NGC 4449, seen in this image released on May 29, 2024. Starbursts are intense periods of star formation usually concentrated at a galaxy's core, but NGC 4449's activity is much more widespread—likely due to past interactions with its galactic neighbors. Astronomers can study this galaxy to look into the past: NGC 4449 is similar to early star-forming galaxies, which also grew by merging with other systems.
NASA: ESA: NGC 4449 resembles primordial star-forming galaxies which grew by merging with and accreting smaller stellar systems. Since NGC 4449 is close enough to be observed in great detail, it is the ideal laboratory for astronomers to study what may have occurred during galaxy formation and evolution in the early Universe.bigg: https://de.wikipedia.org/wiki/NGC_4449# ... scope).jpg
