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.
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.
We get excited when we detect water on another world, which so far hasn’t happened often. But this study shows that the presence of water, though tantalizing and worth pursuing scientifically, guarantees nothing.
The satellite called Icon, or Ionospheric Connection Explorer, will transmit data intended to help scientists understand the physical processes at work where Earth's atmosphere interacts with near-Earth space.
Largest documented asteroid breakup in the asteroid belt during the past two billion years caused enormous amounts of dust to spread through the solar system. The blocking effect of this dust lead to cooler temperatures which in turn caused diversification.
