About 66 million years ago, an estimated 6-mile-wide (9.6 kilometers) object slammed into Earth, triggering a cataclysmic series of events that resulted in the demise of non-avian dinosaurs.
The hidden fragment, dating as old as 1.3 billion years, is helping scientists trace the history of the mysterious “lost continent” of Zealandia.
Scientists may have significantly underestimated how often the early Earth was struck by asteroids, new research suggests.
Space scientists have discovered extra-terrestrial particles which point to a medium-sized asteroid impact in Antarctica 430,000 years ago.
An asteroid shower thought to have struck the moon and Earth 800 million years ago may have helped trigger Earth’s greatest ice ages, a new study finds.
New simulations add to evidence that the Chicxulub strike is what killed T. rex and its kin
Asteroids crashing into the ocean could have helped create the ingredients for life, scientists say.
The smoldering crater left by the apocalyptic space rock became a nice home for blue-green algae within years of the impact.
Marine die-offs after the impact may have created opportunities for the life that survived around the globe, new data reveal.
Source: Science Alert Even before the Chicxulub asteroid hit Earth 66 million years ago, dinosaurs and other life forms were dealing with toxic mercury levels, a new study suggests. The fresh evidence serves up even more contention in a “long-running and bitter” debate over how the dinosaurs died all those years ago. While some scientists
