Scientists have discovered a new way oxygen can form in carbon-dioxide-rich atmospheres of worlds beyond our own —- challenging assumptions about how we should search for life on other planets, and ...

With a zap, a beam of ultraviolet light can blast carbon dioxide into oxygen gas, O 2. Because the sun hurls the same radiation, the reaction hints that breathable air could have formed on Earth ...

Carbon dioxide is being converted into oxygen on Mars thanks to an invention undergoing testing that could lead to the colonization of the red planet. Day and night across the seasons, a ...

New study shows that geological storage of low-purity carbon dioxide mixed with oxygen and nitrogen from direct air capture is an environmentally friendly and economically viable approach to remove ...
