Changes in Earth’s tilt relative to the sun have governed the movements of giant ice sheets over the past 800,000 years, triggering the start and end of eight ice ages, new research suggests. The new study revealed an “amazing correlation” between Earth’s tilt and ice sheet formation, said lead author Stephen Barker. Based on these … Read more
Radiation from an exploding star may have had a profound effect on the evolution of life on Earth, a new study suggests. About 2.5 million years ago, the viruses infecting fish in Africa”s Lake Tanganyika underwent a mysterious and rapid explosion in diversity. Yet the exact cause of this change has remained a mystery. Now, … Read more
We may have been wrong about how Mars got its characteristic red hue, a new study reveals. The Red Planet owes its ruddy complexion to rusted iron minerals, dispersed across billions of years by winds, throughout the planet’s dust. Past spacecraft observations of Martian dust led scientists to believe that this rust emerged in dry … Read more
