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.
