Astronomers have detected a colossal gas outflow at the heart of the distant galaxy NGC 4383. This outpouring, known as a ‘gas outflow,’ stretches across an astonishing 20,000 light-years, approximately one-fifth of the Milky Way galaxy’s diameter.
The discovery, detailed in a paper published in a scientific journal, reveals that the gas is spewing from the galaxy’s core at an astounding rate of over 447,000 miles per hour. Gas outflows, driven by massive stellar explosions, play a crucial role in shaping the evolution of galaxies. By removing gas from the galaxy, these outflows limit the available material for new star formation, affecting the galaxy’s growth and structure.
The gas outflow in NGC 4383 is particularly intriguing as it is thought to be caused by violent stellar explosions near the galaxy’s center. These explosions have ejected vast quantities of hydrogen gas and other elements, up to an estimated 50 million suns’ worth.
The ejected gas is rich in heavy elements, providing scientists with valuable insights into the complex process of mixing between hydrogen and metals in outflows. Researchers have identified the presence of oxygen, nitrogen, sulfur, and other chemical elements in the outflow.
The discovery of this immense gas outflow sheds light on the processes that shape galaxies. By studying this phenomenon, astronomers hope to unravel the mysteries surrounding chemical pollution in the intergalactic medium and better understand the impact of gas outflows on galactic evolution.
