Nearby Dwarf Galaxies Show Surprising Lack Of Oxygen, Says Paper
A new study of more than three dozen dwarf galaxies has surprised researchers with just how little oxygen they have been able to retain over cosmic time. The results reveal that we still have major gaps in our understanding of galaxy evolution.
Astronomers have examined 37 dwarf galaxies using the Hubble Space Telescope. It turns out that they retain only a fraction of the oxygen produced by their stars. Where the rest goes surprises the researchers. Oxygen is the most abundant heavy element in the universe, after hydrogen and helium. Oxygen is primarily formed deep within the interior of massive stars […] More science? Read the latest articles on Scientias.nl.
The GLOW study combined archival Hubble data with other observations to examine how much oxygen 37 nearby dwarf galaxies hold. The article Hubble Spots Oxygen Deficit in 37 Dwarf Galaxies appeared first on FLIGHT.
