New research from Boston University and the Harvard Radcliffe Institute suggests that the sun passed through a massive hydrogen cloud two million years ago, directly impacting the protective heliosphere and possibly permanently altering all life on Earth. 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
Two million years ago, the solar system encountered a dense interstellar cloud that may have significantly affected Earth’s climate by compressing the heliosphere and exposing the planet to high levels of cosmic and galactic radiation.
