Cosmic Winds: The Universe's Shaping Gale

Astronomers using the MUSE instrument on the ESO's Very Large Telescope have discovered that galactic winds, which limit galaxy growth and star formation, are a universal phenomenon in galaxies over 7 billion years old. These winds, formed from massive star explosions, were mapped using magnesium atom emission signals. Future studies aim to measure the extent and matter content of these galactic winds.
