A Gloomy revelation about destructive asteroids has been created by space scientists.
They discovered that space objects huge enough to flatten entire cities burst into our planet more frequently than we estimated.
Researchers analyzed the time of Wolfe Creek Crater, a 2,900ft-wide collision crater in Western Australia.
It’s assumed to have been left by a 14,000-tonne asteroid, which upon contact exploded with the comparable force of 36 nuclear bombs.
Scientists had long considered the collision that took place 300,000 years ago, but it really occurred much beforehand, as per a new study.
Experts at Australia’s University of Wollongong estimated the time of impact confining to 120,000 years ago.
The findings prompted the team to update earlier estimates for how often huge asteroids wreck our planet.
They insisted that a similar impact enough to flatten a small town could happen shorter than once every 200 years.
“Although the time is only one large meteorite hitting Australia every 17,000 years, it isn’t that manageable,” head researcher Professor Tim Barrows stated.
“Since Australia has an outstanding preservation record with recorded craters within the dry zone, we can extrapolate a time for the entire Earth.
“Taking into report that arid Australia is only about one percent of the surface of the earth, the percentage increases to one every 180 years or so.”
“We assume that the maximum diameter of the crater is 946 meters in a NE-SW direction, indicating the path of the impact,” Professor Barrows stated.
The average diameter is 892 meters.
“We prognosticate an intensity of 178 meters and that it is saturated by about 120 meters of sediment, chiefly sand swept in from the desert.“
Our newest collision with a huge space astroid transpired in 1908.
Acknowledged as the Tunguska incident, the explosion over Siberia is the greatest ever recorded comparable to 190 Hiroshima bombs.
75-80 million trees were knocked down across a remote area comprising 800 square miles.
In other space discovery, it surfaced today that a bubble of super-hot gloop encompasses our Solar System and a Nasa probe is held inside it.
The space agency lately confirmed that it almost fumbled an asteroid that skimmed much closer to Earth than the Moon beginning this month.
