The galaxy is located 620 million light years away, situated in the constellation Lynx, UPI reported.
Dubbed J0811+4730, the dwarf galaxy is the most oxygen-deprived star-forming galaxy yet discovered by astronomers. It boasts nine percent less oxygen than the next most oxygen-deficient galaxy.
Because the first few generations of galaxies were relatively simple and oxygen-deprived, researchers believe J0811+4730 can offer unique insights into history of the early Universe.
The first generation of galaxies, which formed roughly 400 million years after the Big Bang, were relatively simple — made up of hydrogen and helium.
Over time, the Universe became more chemically diverse as stellar fusion birthed new, heavier elements, including oxygen.
The earliest low-oxygen galaxies are too faint and faraway to be studied using today's astronomical equipment, but J0811+4730 can serve as a proxy for the smaller, simpler galaxies of the early Universe — a window into the Universe as it was 13 billion years ago.
