A survey of ice in Greenland has uncovered evidence suggesting a kilometer-wide iron asteroid slammed into that island, perhaps as recently as 12,000 years ago during the end of the Pleistocene. The resulting 19-mile-wide ...
Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench.
Once again, humanity might be well served to take heed from a history lesson. When the climate changed, when crops failed and famine threatened, the peoples of ancient Asia responded. They moved. They started growing different ...
Sixty-six million years ago, an asteroid the size of a small city smashed into the earth. This impact, the one that would lead to the end of the dinosaurs, left a scar several miles underground and more than 115 miles wide.
A new study by researchers at The Australian National University (ANU) could help us understand how our planet was formed.
When Australian scientists presented evidence in 2016 of life on Earth 3.7 billon years ago—pushing the record back 220 million years—it was a big deal, influencing even the search for life on Mars.
For the first time, scientists have traced the north-south shifts of the northern-most edge of the tropics back 800 years, reports a University of Arizona-led international team.
When rains fell on the arid Atacama Desert, it was reasonable to expect floral blooms to follow. Instead, the water brought death.
