Scientists reveal a new part of the recipe for complex life on planets, and it involves the onset of a microbial fertilizer factory on the Earth's seafloor roughly 2.6 billion years ago. The first major rise in oxygen levels on the Earth took place roughly 2.4 to 2.2 billion years ago during the early stage of the Great Oxidation Event. Scientists are still unsure why and how the Gre

Over the past two decades, the Arctic has lost about one-third of its winter sea ice volume, largely due to a decline in sea ice that persists over several years, called multiyear ice, according to a new study. The study also found sea ice is likely thinner than previous estimates. Seasonal sea ice, which melts completely each summer rather than accumulating over years, is replacing thicke

In a changing climate, wildfires are becoming more widespread and devastating, threatening more people and land than ever before. In response, NASA is stepping up to the plate to determine what we can do to help fight wildfires - and we have some ideas. NASA has long been involved in wildfire management through the Science Mission Directorate (SMD) using space-based technologies and other

China will carry on its moon research in the future with Chang'e-6, Chang'e-7 and Chang'e-8 missions by 2030, chief designer of the country's lunar exploration program Wu Weiren said. The Chang'e-6 is scheduled to bring back to Earth lunar samples with a mass of up to 2 kilograms; the Chang'e-7 will be tasked with landing on the lunar south pole and detecting local natural resources; and t

The tectonic plates that form the Earth's surface are like puzzle pieces that are in constant, very slow motion - on average, they move only up to around 10 centimeters a year. But these puzzle pieces don't quite fit together: there are zones on one plate that end up plunging under another - the so-called subduction zones, central to the dynamics of the planet. This movement is slow, but it can

Industry experts say US and European economic sanctions against Russia for military action against Ukraine could create economic opportunities for the Indian space sector, rather than burden it with economic costs. He also felt that to seize the opportunity, India should accelerate its satellite launching capabilities, and announce Productivity Concessions (PLI) schemes for the aerospace s
