American astronauts who return to the moon’s surface in the years ahead for the first time in more than half a century will have the difficult and unprecedented task of setting the stage for a permanent human lunar settlement. That may be the primary objective for spacefarers in NASA’s Artemis lunar program, but it won’t be their only one. Indeed, …

The Moon’s Largest Crater Has Something Odd Going on – And Astronauts Are Heading There : ScienceAlert
The gravitational interaction between the Earth and Moon has led to one hemisphere of the Moon being locked facing away from Earth. Don’t be misled, though. The Moon does rotate, it just takes as long to rotate once on its axis as it takes to complete an orbit of Earth. This is known as synchronous rotation, and on the far …

Scientists have found that we may have been wrong about how the Moon’s largest crater, the South Pole-Aitken (SPA) basin, formed roughly 4.3 billion years ago. As detailed in a new paper published in the journal Nature, the more than 1,200-mile crater appears to have been the result of a glancing, southward blow — and not a head-on asteroid impact, …

scientists have unveiled a colossal underwater crater beneath Chesapeake Bay, three times the size of the Grand Canyon. Formed by an asteroid strike 35 million years ago, this discovery reshapes our understanding of catastrophic events in Earth’s history. It echoes findings from a recent Meteorite & Planetary Science study, which explores how such impacts have dramatically influenced Earth’s climate and …

Sometime in the Middle Eocene epoch, nearly 50 million years ago, a large object hurtled through Earth’s atmosphere, crashing into the North Sea between what’s now Britain and northwestern Europe. The impact formed a crater 1 kilometer (about half a mile) deep and 3 kilometers wide. A plume of debris and water blasted skyward before falling back down, triggering a …

After two decades of debate, researchers say they finally have definitive proof that the Silverpit Crater, a buried structure in the North Sea, was created by an asteroid strike more than 40 million years ago. The crater, discovered in 2002 about 80 miles (129 kilometers) off the Yorkshire coast, is 1.8 miles (3 km) wide and lies some 766 yards …

Natural glass found only in Australia could be evidence of an unknown, ancient asteroid impact, researchers say. A new analysis of impact-created “tektites” points to a powerful collision millions of years ago that hurled debris across southern Australia. Scientists are still looking for the impact crater. “These glasses are unique to Australia and have recorded an ancient impact event we …

Deep below the seabed, 80 miles off the coast of Yorkshire, is a remarkable crater that has divided scientists – was it, thrillingly, created by an asteroid crash? Or more mundanely was it the result of geological salt movements? Today, the decades-long scientific debate can be settled. The Silverpit crater 700 metres below the seabed under the North Sea was …
