"Discovery of Massive Interstellar Winds Shaking the Distant Cosmos"
Originally Published 2 years ago — by Ars Technica
Scientists have made the first direct observations of galactic winds in a large population of galaxies in the distant Universe, shedding light on the early stages of galaxy formation. Galactic winds, produced by supernovae, play a crucial role in regulating star formation and shaping the evolution of galaxies. These winds inject energy and momentum into the gas, causing it to be expelled from the galaxy. The study used the MUSE instrument on the Very Large Telescope to detect and observe the emission from magnesium atoms in over 100 galaxies, revealing the average shape of these winds to be like an ice cream cone. Further research is needed to understand the physical properties and variations of galactic winds.
