Hubble Telescope Finds Oxygen Shortage in Nearby Dwarf Galaxies

• NASA's Hubble Space Telescope found that small galaxies have less oxygen than expected.
• Researchers studied 37 dwarf galaxies within 22 million light-years from Earth.
• These dwarf galaxies are much smaller than the Milky Way.
• The study suggests that these galaxies lose most of the oxygen produced by their stars.
• The findings were published by NASA and reported by multiple outlets.
