NASAâs Webb Reveals Intricate Networks of Gas and Dust in Nearby Galaxies

Young starsâ impact on galaxy evolution explored with PHANGS program
The saying goes, âFrom a tiny acorn grows the mighty oak.â This is accurate not just here on Earth, but in our solar system and beyond. Even on a galactic scale, where individual stars and star clusters can sculpt a galaxy's overall structure. Scientists say NASAâs James Webb Space Telescope is perfectly primed to study these phenomena, and the first data is astounding astronomers.
New imagery from Webbâs Mid-Infrared Instrument is revealing never-before-seen details into how young, newly forming stars influence the structure of the gas and dust of nearby galaxies, and therefore how they evolve over time. Areas of galaxies that once appeared dim and dark in visible light, now under Webbâs infrared eye, are glowing cavities and huge cavernous bubbles of gas and dust.
