NASA’s Hubble Uncovers Case of Missing Oxygen in Nearby Dwarf Galaxies - NASA Science
Researchers found dwarf galaxies keep only a small share of the oxygen made by stars, suggesting supernova-driven winds remove more than models predict.

Nearby Dwarf Galaxies are Missing Most of Their Oxygen, Hubble Data Show
Gas-rich dwarf galaxies appear to retain only about a tenth of the oxygen their stars have made, according to a census of 37 nearby systems using data from the NASA/ESA Hubble Space Telescope. The post Nearby Dwarf Galaxies are Missing Most of Their Oxygen, Hubble Data Show appeared first on Sci.News: Breaking Science News.
Stars make oxygen for small galaxies, but they lose most of it
Scientists examining data collected by NASA's Hubble Space Telescope have found that dozens of small galaxies contain far less oxygen than their stars are estimated to have produced. The researchers, including a Rutgers astrophysicist, studied 37 dwarf galaxies, which are much smaller than the Milky Way and considered to be nearby, within 22 million light-years of Earth. The results were published in The Astrophysical Journal.
