Scientists Discover a Massive Underwater Crater Beneath Chesapeake Bay—Three Times the Size of the Grand Canyon

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 …

Unusual Crater in The North Sea Result of a Cosmic Collision, Study Confirms : ScienceAlert

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 …

Weird glass in Australia appears to be from giant asteroid impact — but scientists ‘yet to locate the crater’

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 …
