Astronomers are examining why galaxies formed in the early Universe stopped growing and eventually died. These early galaxies began as small clusters of matter that merged to create larger galaxies.

To explore these phenomena, researchers employ instruments like the James Webb Space Telescope (JWST), which can detect infrared light emitted by distant, ancient galaxies. By analyzing this data, they aim to better understand the processes that influenced galaxy evolution in the Universe's infancy.
