The aftermath of the asteroid collision, which occurred approximately 66 million years ago, is believed to have caused the mass extinction of non-avian dinosaurs and many other species on Earth. [13] The impact spewed hundreds of billions of tons of sulfur into the atmosphere, producing a worldwide blackout and freezing temperatures which ...
The Kamchatka superbolide is estimated to have had a mass of roughly 1600 tons, and a diameter of 9 to 14 meters depending on its density, making it the third largest asteroid to impact Earth since 1900, after the Chelyabinsk meteor and the Tunguska event. The fireball exploded in an airburst 25.6 kilometres (15.9 mi) above Earth's surface.
The giant S2 meteorite hit Earth 3 billion years ago. It was four times the size of Mount Everest, unleashed a tsunami bigger than any in known human history and boiled the oceans — but an ...
When a meteorite with the mass of four Mount Everests hit Earth 3.2 billion years ago, it caused global chaos and provided an unexpected silver lining for life.
Harvard researchers found that when a meteorite nicknamed S2 paid a visit to our planet 3 billion years ago, it may have helped life flourish. Giant meteorite that hit Earth 3 billion years ago ...
Collisions between ejecta escaping Earth's gravity and asteroids would have left impact heating signatures in stony meteorites; analysis based on assuming the existence of this effect has been used to date the impact event to 4.47 billion years ago, in agreement with the date obtained by other means.

The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian structures are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry, [ 33 ] with the small but well-funded European continent having a large percentage of ...
The impactor hit with so much energy that it and whatever sediment or rock it hit vaporized. This rock vapor cloud and dust ejected from the crater would have circled the globe and turned the sky ...
