European Space Station observatory has recorded five blue flashes from the top of a storm cloud, one of which ended with a blue jet streaking high into the stratosphere. Our understanding of these blue jet lightnings is limited.
The mass of human-made products at the start of the 20th ct was about 3% of the Earth’s biomass. However, due to increased urbanization and consumption, human-produced weight now outweighs the overall global biomass.
Sentinel-6 satellite lifted off on a SpaceX Falcon 9 rocket on Nov 21. Its mission now is to measure and chart the rise of the sea level more precisely than ever before.
Recent findings suggest that relatively close supernovas could theoretically have triggered at least four disruptions to Earth's climate over the last 40,000 years. What happens in space may not always stay in space.
When the asteroid struck our planet some 66 mil years ago, it created a 180-km impact crater and produced a gigantic magma chamber. A new research found that this hydrothermal system supported an entire microbial ecosystem.
Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth.
The South Atlantic Anomaly is a vast expanse of reduced magnetic intensity in Earth's magnetic field, extending all the way from South America to southwest Africa.
100 million years ago, ferocious predators, including flying reptiles and crocodile-like hunters, made the Sahara the most dangerous place on Earth.
A robotic servicing spacecraft has hooked up with an aging satellite over the Pacific Ocean. It accomplished the first link-up between two commercial satellites in space, and the first docking with a satellite that was never designed to receive a visitor.
