On June 30, 1908, an asteroid plunged into Earth’s atmosphere and exploded in the skies over Siberia. Local eyewitnesses in the sparsely populated region reported seeing a fireball and hearing a large explosion. They also reported massive forest fires, and trees blown over for miles. Because of the remoteness of the site, the event garnered
There are about 190 proven and possible meteorite impact structures scattered throughout the world. The Canon Diablo ('Devil's Canyon') crater in Arizona, USA, has a 1.5 km diameter and is 170 m deep. The meteorite which made this crater may have been 30,000 to 100,000 tonnes, and an estimated 10 m - 25 m in diameter.
The generation of submarine hydrothermal vents through meteorite impacts also circumvents a major problem for this origin-of-life hypothesis; namely that it is very uncertain as to whether black and white smoker-type environments—which at the present-day are associated with mid-ocean ridges—would have existed on early Earth due to the
A cataclysmic impact . When the dinosaur-killing asteroid, which likely measured around 7.5 miles (12 km) wide, hit Earth around 66 million years ago, the destruction caused by the impact was immense.
Meteors Great and Small. 1988 - 2021 PNG. Abundant streaks of light have raced across the night sky this week during the peak of the Perseid meteor shower. The light show happens every year in mid- to late-August when Earth’s orbit intersects with the trail of debris left by Comet Swift-Tuttle. While the Perseids and other major showers
