A new study links a slew of extra-terrestrial impacts millions of years ago to our planet’s most unique feature—plate tectonics.
A controversial theory that suggests an extraterrestrial body crashing to Earth almost 13,000 years ago caused the extinction of many large animals and a probable population decline in early humans is gaining traction from research sites around the world.
One of the planet’s most dramatic extinctions was caused in part by ocean acidification, which has become a problem in our own era.
466 million years ago, the break-up of a large space rock may have led to major changes in our planet’s biodiversity
The metallic asteroid Psyche has mystified scientists because it is less dense than it should be, given its iron-nickel composition. Now, a new theory could explain Psyche’s low density and metallic surface.
When a colossal space rock came crashing down 66 million years ago onto what is now the Yucatan Penninsula in Mexico, it triggered widespread changes on Earth and abruptly ended the reign of the dinosaurs. Now, researchers are focusing on learning the extent of the asteroid’s destructive might and the immediate aftermath at ground zero, a location now known as the Chicxulub crater.
The heavy bombardment of terrestrial planets by asteroids from space has contributed to the formation of the early evolved crust on Earth that later gave rise to continents — home to human civilisation.
Scientists have discovered a 31km wide impact crater beneath the Hiawatha glacier in Greenland. The discovery, published in Science Advances, was made using airborne radar surveys which unveiled a circular bedrock depression beneath the ice. The presence of quartz and other grains and features on the ground helped the team confirm the finding – these
It is the first impact crater discovered under one of Earth’s ice sheets, according to the scientists who found it.
Asteroid pair is the ‘smoking gun’ indicating an earlier altercation amongst the giants
