- An international team of astronomers has detected large amounts of oxygen in the atmosphere of one of the oldest and most elementally depleted stars ever known.
- The new finding, made using WM Keck Observatory on Maunakea in Hawaii to analyze the chemical makeup of the ancient star called 'J0815+4729,' provides an important clue on how oxygen and other important elements were produced in the first generations of stars in the universe.
- Oxygen is the third most abundant element in the universe after hydrogen and helium but it does not occur naturally.
