The Earth and Moon May Have Formed Later Than Previously Thought
The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now it was thought to have happened when the solar system was 30 million years old or approximately 4.5 billion years ago. But new research shows that the Earth and Moon may [...]

Does Zonal Swishing Play a Part in Earth's Magnetic Field Reversals?
Why does the Earth's magnetic field 'flip' every million years or so? Whatever the reason, or reasons, the way the liquid iron of the Earth's outer core flows – its currents, its structure, its long-term cycles – is important, either as cause, effect, or a bit of both. The main component of the Earth's field – [...]

Deep, Fiery Undersea Volcano Captured on Video
Oceanographers using a remotely operated underwater vehicle discovered and recorded the first video and still images of the deepest underwater volcano actively erupting molten lava on the seafloor. The ROV Jason vehicle captured the powerful event nearly 1.2 km (4,000 feet) below the surface of the Pacific Ocean, in the "Ring of Fire" region, near [...]

Earth's Atmosphere Came from Outer Space
A new study finds the gases which formed the Earth's atmosphere – as well as its oceans – did not come from inside the Earth but from comets and meteorites hitting Earth during the Late Heavy Bombardment period. A research team tested volcanic gases to uncover the new evidence. "We found a clear [...]

Jupiter – Our Silent Guardian?
We live in a cosmic shooting gallery. In Phil Plait's Death From the Skies, he lays out the dangers of a massive impact: destructive shockwaves, tsunamis, flash fires, atmospheric darkening…. The scenario isn't pretty should a big one come our way. Fortunately, we may have a silent guardian: Jupiter. (...)Read the rest of Jupiter – Our [...]

Heat-Shocked Diamonds Provide New Clue of Horse-Killing Impact
Archeologists have been divided about whether an extraterrestiral impact blasted North America about 12,900 years ago, wreaking havoc on Earth's surface and sending scores of species — including a pygmy mammoth and the horse — into oblivion. New clues from California's Channel Islands should put any doubt to rest, says an international team of researchers. (...)Read the [...]
