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.
It looks like another extinction prior to the appearance of the dinosaurs paved the way for their long reign. That extinction took place about 233 million years ago. And scientists have only now discovered it.
A new study finds that Earth's water may have come from materials that were present in the inner solar system at the time the planet formed - instead of far-reaching comets or asteroids delivering such water.
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.
Scientists believe that immense quantities of methane are stored under Antarctica’s seafloor. They don’t know the leak’s cause, but global warming probably isn’t to blame, since the Ross Sea has not yet warmed significantly.
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 team of scientists drilled into the ground near the South Pole to discover that 90 million years ago Antarctica was once home to a swampy rainforest and had average temperatures around +11C.
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.
Scientists have discovered Earth's oldest asteroid strike occurred at Yarrabubba, in outback Western Australia 2,2 billion years ago, and coincided with the end of a global deep freeze known as a Snowball Earth.
A NASA scientist analyzed the age of the Yarrabubba meteor crater in Australia and found it to be 2.229 billion years old, making it now the oldest crater currently known.
Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the asteroid.
In 2018, a large number of seismic alerts had been detected everywhere. They created a weird buzzing sound. Now the mysterious hum is identified as rumblings of a magma-filled reservoir deep under the Indian ocean where the new volcano is forming.
