Oxygen-deficient Dwarf Galaxy Hints at Makings of Early Universe

Professor Trinh Thuan and colleagues recently discovered a dwarf galaxy in the constellation Lynx that is so oxygen-deficient that may serve well as a proxy for better understanding the developing chemistry of the early universe.Their new finding, to be published in the journal Monthly Notices of the Royal Astronomical Society, shows that the oxygen level in the little galaxy is the lowest yet discovered in any star-forming galaxy, likely resembling nascent galaxies in the early universe.
