A NASA scientist analyzed the age of the Yarrabubba meteor crater in Australia and found it to be 2.229 billion years old, making it now the oldest crater currently known.
Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the asteroid.
The title of Earth’s Earliest Life has been returned to the fossils in the Pilbara region of Australia. A new study of the Pilbara fossils has identified the presence of preserved organic matter in those fossils.
Called the "frozen dragon of the north," a new species of flying dinosaur, Cryodrakon boreas, has been discovered in Canada. The pterosaur is thought to have had the wingspan of a small airplane.
Largest documented asteroid breakup in the asteroid belt during the past two billion years caused enormous amounts of dust to spread through the solar system. The blocking effect of this dust lead to cooler temperatures which in turn caused diversification.
Researchers have discovered a remarkably complete 3.8-million-year-old cranium of Australopithecus anamensis at Woranso-Mille in Ethiopia. Due to its rare state, the researchers identified never-before-seen facial features in the species.
New research by a team of UK scientists has located the site of the massive impact that took place in Scotland 1.2 billion years ago. Roughly one billion years ago, Earth experienced a higher rate of meteorite impact than it does today.
A team of scientists has re-created some of the first steps of life in the lab, testing whether life could emerge on other ocean worlds.
The preservation of trace fossils, suggests that multicellular organisms that could move around to reach food resources may already have existed 2.1 billion years ago, more than 1.5 billion years older than previously thought.
An international team of scientists found evidence that the rock was launched from Earth by a large impacting asteroid or comet. The impact sent material into space, where it collided with the surface of the Moon 4 bil years ago.
Microbes could have performed oxygen-producing photosynthesis at least one billion years earlier in the history of the Earth than previously thought.
An international team has discovered a 31-km wide meteorite impact crater buried beneath the ice-sheet in the northern Greenland. This is the first time that a crater of any size has been found under one of Earth.
Antarctica was once part of the supercontinent Gondwana, which began to disintegrate some 130 million years ago, although the bond between Antarctica and Australia held together as recently as 55 million years ago.
A 9.7-million-year-old discovery has left a team of German scientists scratching their heads. The teeth seem to belong to a species only known to have appeared in Africa several million years later.
Could the building blocks for life on Earth have been delivered by meteorites crashing into ponds of water 4 billion years ago?
