Asteroids May Have Delayed The Birth of Earth's First Continents
An AI simulation of an impact shows basalt-rich (purple) and basalt-poor (green) regions. (Curtin University) The planet Earth we live on today bears very few traces of its infancy. The 500 million ...

Water seeping into Earth’s mantle 3.1 billion years ago fueled early volcanic activity and plate tectonics
Water may have been shaping Earth’s deep interior far earlier than many geologists thought. In rocks more than 3 billion ...
Long before oceans teemed with life, Earth endured relentless violence. Asteroids slammed into its surface again and again, reshaping the young planet.
Earth is the only life-supporting planet we know of, so it's tempting to use it as a standard in the search for life elsewhere. But the modern Earth can't serve as a basis for evaluating exoplanets ...
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 ...
The Earth and moon have been locked in a gravitational dance for billions of years. Each day, as the Earth turns, the moon tugs upon the oceans of the world, causing the rise and fall of tides. As a ...
Water has made the Earth the planet that it is—a planet known for its blue oceans. Water shapes the land through erosion and is fundamental to Earth’s ability to support life. But we have a hard time ...
When you think about a large asteroid impact, you might imagine a moment of devastation: a violent collision, a blast of heat and debris, and then years of atmospheric disruption and damage left ...
Ancient asteroid impacts may have done more than reshape Earth's surface—they could have helped spark life itself. New computer models show the collisions created enormous underground hydrothermal ...
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, ...
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 (above) and may ...
