From BRIGHT SIDE.

The James Webb Space Telescope has blown our minds again, uncovering how tiny galaxies played a huge role in building the universe. These small galaxies, way back in the early days of the cosmos, were like cosmic overachievers, cranking out stars like there was no tomorrow. JWST’s powerful infrared vision revealed these faint, ancient galaxies that we couldn’t see before. Turns out, their energy and light helped shape the universe, contributing to something called reionization, which made the universe clear and starry like we know it now. It’s wild to think that these tiny galaxies did so much heavy lifting in the grand cosmic plan. Basically, the JWST just gave us another reason to geek out over the universe!
