Writer Fuel: Scientists Map Lost “Atlantis” Continent Off of Australia

Atlantis - Deposit Photos

One of the most extraordinary stories of human migration unfolded around 70,000 years ago, as humans crossed from Southeast Asia into modern-day Australia, traversing a now-submerged, Atlantis-like landscape, and becoming the first people to call that land home. A rich archaeological record provides ample evidence that this happened. But researchers have long been stumped by … Read more

Mars terraformed - deposit photos

A collection of rocks scattered on an ancient shoreline on Mars might indicate that the Red Planet was once far more Earth-like than scientists previously thought. The rocks, discovered by NASA’s Curiosity rover, are unusually rich in manganese oxide — a chemical that adds to growing evidence that the once-habitable Mars may have sported Earth-like … Read more

The moon is much more seismically active than we realized, a new study shows. A reanalysis of abandoned data from NASA’s Apollo missions has uncovered more than 22,000 previously unknown moonquakes — nearly tripling the total number of known seismic events on the moon. Moonquakes are the lunar equivalent of earthquakes, caused by movement in … Read more

Currently, it is impossible to accurately predict when and where an earthquake might strike. But scientists now believe that Global Positioning System (GPS) data could help spot early warning signs two hours before a big quake strikes. Earthquakes occur when the slabs of slow-moving rocks just under Earth’s surface — known as tectonic plates — … Read more

Writer Fuel: Gigantic Lava Eruptions May Have Turned Earth into a Snowball 717 Million Years Ago

ice planet - deposit photos

Devastating volcanic eruptions may have been so enormous they turned the planet into “Snowball Earth” 717 million years ago, a study has found. The volcanic outburst — one of the largest in Earth’s history — likely triggered a series of chemical reactions that sucked carbon dioxide (CO2) from Earth’s ancient atmosphere. The massive eruptions, which … Read more
