Another Galaxy with Breathable Oxygen Actually Exists
via SyFy
Molecular oxygen has been detected outside our galaxy for the first time ever. Molecular oxygen, or O2, meaning each molecule is made of two oxygen atoms, is the same type we breathe here on Earth without even thinking about it. We thought Earthlings were alone in that. Not to say that aliens (if they exist) breathe O2 or even need it, but finding it 600 million light years away could tell us something about how it might have helped worlds outside our own evolve and even possibly spawn life.
