The James Webb Space Telescope (JWST) has unveiled mesmerizing images of 19 distant spiral galaxies, offering astronomers unprecedented insights into the intricate structures of these cosmic marvels. The images, part of the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) program, showcase the galaxies' stars, gas, and dust in remarkable detail.
Equipped with advanced infrared technology, the JWST captured the galaxies' features with breathtaking precision, revealing clusters of stars, glowing lanes of dust, and sprawling gas clouds. These images provide valuable data for understanding how stars form and galaxies evolve over time.
One of the most intriguing findings is the presence of spherical voids within the galaxies' gas and dust, believed to be the remnants of exploded stars. This discovery sheds light on the dynamic processes shaping these celestial objects.
Moreover, the JWST's observations support the theory that galaxies grow from the inside out, with star formation initiating at the core and propagating outward along the spiral arms. The images also reveal regions of intense star formation, where young stars are clustered together in vibrant blue hues.
