Evidence for this event and its effects on Earth’s climate also shows that the Sun’s location in the … Read more
The Pleistocene Epoch – with its glaciers, woolly mammoths and Neanderthals – still looms large in Earth’s rearview mirror, having ended just 12,000 years ago. Now a team of researchers proposes that those hundreds of thousands of years of our planet’s history may have been cold due to a cloud in space that briefly removed … Read more
