Ancient magnetic fields on the Moon could be protecting precious ice | Science

by

For years, scientists have believed frigid craters at the Moon’s poles hold water ice, which would be both a scientific boon and a potential resource for human missions. Now, researchers have discovered a reason why the ice has persisted on an otherwise bone-dry world: Some polar craters may be protected by ancient magnetic fields. “It’s … Read more

Satellites show Arctic sea ice is melting even faster than scientists realized

by

A new study based on NASA and ESA satellite data shows that Arctic sea ice is thinning at a “frightening rate.” Measuring the ice via satellites each month from 2018 to 2021, polar scientists Sahra Kacimi of the California Institute of Technology’s Jet Propulsion Laboratory and Ron Kwok of the University of Washington’s Applied Physics … Read more

Arctic Ice Already Thinning at a ‘Frightening Rate’, Satellites Reveal

by

New satellite data has revealed the Arctic is melting at a “frightening rate” due to the excess heat caused by human greenhouse gas emissions.  End-of-season Arctic multiyear sea ice – the ice that persists over several years – was roughly 50 centimeters (1.6 feet) thinner in 2021 than it was in 2019, the figures show, … Read more

Huge Crater Under Greenland Glacier Surprises Scientists With Its True Age

by

An enormous impact crater, hiding deep beneath Greenland’s Hiawatha glacier, is probably the result of a kilometer-wide asteroid that crashed into Earth 58 million years ago. That’s much older than scientists presumed – roughly eight million years after the infamous impact that killed off most dinosaurs.   When the Hiawatha crater was first discovered in … Read more

Ice Age Animals Come to Life via Augmented Reality

by

Have you ever wanted to eat breakfast sitting across from a dire wolf or watch a saber-toothed cat roar from the comfort of your living room? These ice age animals have been extinct for more than 10,000 years, but scientists are bringing them back to life—virtually. The team developed three-dimensional, animated models of some of … Read more

Controversial impact crater under Greenland’s ice is surprisingly ancient | Science

by

In 2018, an international team of scientists announced a startling discovery: Buried beneath the thick ice of the Hiawatha Glacier in northwest Greenland is an impact crater 31 kilometers wide—not as big as the crater from the dinosaur-killing impact 66 million years ago, but perhaps still big enough to mess with the climate. Scientists were … Read more

Kidney transplants: Electric field keeps cells powered up while organs are on ice

Shackleton’s Famous Antarctic Shipwreck Finally Discovered in The World’s ‘Worst Sea’

by

Explorers have found one of the most famous shipwrecks in history, Ernest Shackleton’s Endurance, deep in the icy sea off Antarctica more than a century after it sank, they announced Wednesday.   Endurance was discovered at a depth of 3,008 meters (9,869 feet) in the Weddell Sea, about six kilometers (four miles) from where it … Read more

Patagonia Is Rapidly Rising Up in The Largest Glacial Adjustment Ever Recorded

by

Patagonian ice fields are among some of the fastest-melting glaciers on the planet. As these glaciers disappear, the earth that once lay beneath them is rebounding upwards at rates much faster than expected.   Now, scientists have worked out a gap in tectonic plates that began forming some 18 million years ago underneath now-shrinking ice … Read more
