“Iron snow” falling in the core gives planets wavering magnetic fields
The intensely hot interior of planets isn’t somewhere you’d expect to find snow, but scientists do suspect that “iron snow” falls on the Earth’s core. Now, a new study has modeled the dynamics in the lab and found that iron snow could make magnetic fie… Continue reading “Iron snow” falling in the core gives planets wavering magnetic fields
Ruins of long-lost planet may have been discovered near Earth’s core
We only have to look up at the Moon to see the remains of a cataclysmic collision between two early planets, billions of years ago. Now scientists suggest evidence may also be deep beneath our feet, as the remains of that ancient planet lurk near the E… Continue reading Ruins of long-lost planet may have been discovered near Earth’s core
Scientists identify new accomplice in death of the dinosaurs – dust
A giant asteroid is credited for killing off the dinosaurs, but it wasn’t the rock alone – the cascading effects of the impact destroyed Earth’s livability for millennia. Now scientists have identified a new factor, in fine silicate dust that hung in t… Continue reading Scientists identify new accomplice in death of the dinosaurs – dust
Lava studies suggest Earth’s core is leaking
Scientists from Caltech and Woods Hole Oceanographic Institution (WHOI) have found evidence that Earth’s core is leaking. High levels of a particular isotope of helium were found in lava flows in Canada, which the team proposes originated in the planet… Continue reading Lava studies suggest Earth’s core is leaking
Future supercontinent predicted to trigger a mammal Armageddon
About 66 million years ago, the reign of the reptiles came to a dramatic end as a huge asteroid slammed into Earth. Scientists have now predicted that mammals will meet their maker in a similar cataclysm in about 250 million years’ time, as the contine… Continue reading Future supercontinent predicted to trigger a mammal Armageddon
Dinosaur ‘Coliseum’ reveals prehistoric pedestrian pathway
Scientists have found a massive area the size of 1.5 football fields, now dubbed “The Coliseum,” which was once a popular thoroughfare to water for multiple species of prehistoric beasts over many generations some 70 million years ago.Continue ReadingC… Continue reading Dinosaur ‘Coliseum’ reveals prehistoric pedestrian pathway
Fabulous 500-million-year-old annelid named after Dune’s epic sandworms
A new species of ancient sea worm with an impressively elaborate set of star-shaped chaetae has been discovered after its puzzling fossilized form was found to be animal not mineral. And just as impressive, the 500-million-year-old aquatic annelid has … Continue reading Fabulous 500-million-year-old annelid named after Dune’s epic sandworms
Billion-year conspiracy between Sun and Moon prevented 60-hour days
If you’ve ever felt like you need more hours in the day, well how does 60 sound? A new study suggests we’d have 60-hour days by now if a stalemate between the Sun and Moon hadn’t interfered with Earth’s rotation for over a billion years.Continue Readin… Continue reading Billion-year conspiracy between Sun and Moon prevented 60-hour days
Earth’s solid inner core may have pockets of liquid iron
The Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been assumed, but might have pockets of liquid iron throughout.Conti… Continue reading Earth’s solid inner core may have pockets of liquid iron
