Earth's Early Oxygen May Have Come From Rocks — And It Could Have Big Implications For Life in Space
One broken piece of quartz in a physics lab could shed light on the history of life on Earth and the search for other habitable worlds. Today, most life as we know it depends on oxygen. Specifically, ...
IMAGE: A new study by CU-Boulder researchers indicates a thick organic haze shrouding Earth several billion years ago was similar to the one now hovering over Saturn’s largest moon, Titan. University ...
