2 giant blobs in Earth’s mantle may explain Africa’s weird geology

Deep within Earth’s mantle, there are two giant blobs. One sits under Africa, while the other is almost precisely opposite the first, under the Pacific Ocean. But these two blobs are not evenly matched.  New research finds that the blob under Africa extends far closer to the surface — and is more unstable — than … Read more

Radical Plan to Make Earth’s Deepest Hole Could Unleash Limitless Energy

Since its launch in 2020, a pioneering energy company called Quaise has attracted some serious attention for its audacious goal of diving further into Earth’s crust than anybody has dug before.   Following the closure of first round venture capital funding, the MIT spin-off has now raised a total of US$63 million: a respectable start … Read more

Watery graves: Should we be ditching big spacecraft over Earth’s oceans?

With increasing regularity, Earth’s oceans are the drop zones for incoming leftovers from space.  For decades, Russian Progress resupply spacecraft loaded with tons of waste from the International Space Station (ISS) have been intentionally steered to reentries over the Pacific Ocean’s “spacecraft cemetery.” Similarly, Northop Grumman’s Cygnus cargo vehicles are filled with rubbish from the … Read more

Cambrian explosion: First burst of animal evolution altered chemical makeup of Earth’s mantle

The Cambrian explosion 500 million years ago saw a huge variety of animals evolve – and also led to carbon being buried in the seabed and ultimately carried into the planet’s mantle Earth 4 March 2022 By Michael Marshall The explosion of new species in the Cambrian period saw the emergence of many familiar groups … Read more

Scientists Can Now Trace Earth’s History in Individual Grains of Sand

Grains of sand on a beach can tell us more than you might think about the history of the planet, new research reveals – something to think about the next time you’re heading to the coast for a swim or splash around.   Scientists have developed a new metric to determine what they call the … Read more

Ingenious System to Pulverize Asteroids May Be Earth’s Only Chance in a Catastrophe

Gazing at the night sky can evoke a sense of wonder regarding humanity’s place in the Universe. But that’s not all it can evoke. If you’re knowledgeable about asteroid strikes like the one that wiped out the dinosaurs, then even a fleeting meteorite can nudge aside your enjoyable sense of wonder.   What if? Luckily, … Read more

Powerful GOES-T satellite launches to eye Earth’s weather, climate

Scientists will soon have a powerful new set of eyes in the sky to study Earth’s weather and climate. The GOES-T satellite lifted off from Florida’s Cape Canaveral Space Force Station today (March 1) at 4:38 p.m. EST (2138 GMT), riding a United Launch Alliance Atlas V rocket into the final frontier. If all goes … Read more

Mysterious new substance possibly discovered inside Earth’s core

Earth’s inner core may be filled with a weird substance that is neither solid nor liquid, according to a new study. For more than half a century, scientists believed that Earth‘s deepest recesses consist of a molten outer core surrounding a densely compressed ball of solid iron alloy. But new research, published Feb. 9 in the journal Nature, offers a … Read more

New GOES-T weather satellite to offer scientists sharper eyes on Earth’s climate

The GOES-T satellite is ready to take its place as part of the U.S.’s most sophisticated weather and environmental observation system. The satellite, which will be operated by the U.S. National Oceanic and Atmospheric Administration (NOAA) will launch on Tuesday (March 1) aboard a United Launch Alliance Atlas V rocket blasting off from Cape Canaveral … Read more
