Hubble Study Shows Dwarf Galaxies Retain Limited Oxygen

The NASA/ESA Hubble Space Telescope has revealed that dwarf galaxies retain only about 11% of the oxygen produced by their stars. This suggests these smaller galaxies are significant contributors to seeding intergalactic space with oxygen, an element vital for life. Strong stellar winds from massive stars, coupled with weaker gravitational pull, are believed to expel much of this oxygen.
