Analysis of meteorites that reached the Earth long after the cosmic collision which created the Moon indicate the satellite is 4.47 billion years old, according to an article published in the journal Science.
Paleontologists have described a new species of terror bird, dubbed Llallawavis scagliai, which thrived on Earth 3.5 million years ago, based on some of the most complete fossil remains ever recovered for one of these creatures in Argentina.
In a warning of how lethal increased carbon dioxide emission could be, researchers found the greatest extinction of all time that happened 252 million years ago was due to the huge amount of carbon dioxide the Earth's oceans absorbed from volcanic eruptions.
A new study has revealed that acidic oceans triggered greatest extinction of all time 252 million-years-ago, which wiped out more than 90 per cent of marine species and more than two-thirds of the animals living on land.
Sharing a fresh view of how the Moon was formed, a team of scientists at University of Maryland has generated a new isotopic fingerprint -- the geological equivalent of a DNA "fingerprint" -- of the Moon suggesting that the Earth and its satellite were formed from the same foreign body.
