A fireball exploded in the sky: it was 10 times more powerful than the Hiroshima bomb – 03/18/2019

A big fireball exploded in the atmosphere of the Earth. It arrived in December, but it was only released Monday by NASA. It is the explosion of a meteorite, which was ten times more powerful than the atomic bomb dropped on Hiroshima (Japan) in 1945.

The explosion, which was detected by US military satellites, occurred over the Bering Sea, off the Kamchatka Peninsula, a remote region of Russia. That's why it went unnoticed.

According to NASA, this explosion was the second strongest of its kind in the last 30 years and is the largest meteorite to have reached the Earth's atmosphere from which it arrived in Chelyabinsk (Russia) in 2013.

In this case, the shock wave of the impact caused nearly 1,500 injuries.

The asteroid that hit the Bering Sea in December went through the atmosphere at a speed of 32 kilometers per second, following a trajectory of seven degrees.

The meteorite exploded about 25.6 kilometers above the Earth's surface, with an impact energy of 173 kilotons, according to NASA data.

"That accounted for 40% of Chelyabinsk's energy, but it was above the Bering Sea, so it did not have the same kind of effect and that's not the case." "It has not appeared in the news," said Kelly Fast, head of NASA's near-Earth object observation program. "It's another thing we have for our defense: there is a lot of water on the planet," he said.

Fast presented the details of the event at the L Lunar and Planetary Science Conference at The Woodlands, near Houston, Texas.

The military satellites took the explosion last year and NASA was informed by the US Air Force.

This is a rare phenomenon: Lindley Johnson, NASA's global defense officer, told BBC News that a fireball so big is only expected two or three times every 100 years.

Although it had no impact on the sea, NASA experts estimated that the explosion was ten times greater than the one that dropped the atomic bomb on Hiroshima on the instructions of US President Harry Truman.

This nuclear attack on the Japanese Empire caused the death of more than 20,000 soldiers and about 100,000 civilians in the Japanese city.

The specialized media reported that the meteorite had crossed an area "not very far" from the routes used by commercial aircraft flying between North America and Asia, so the researchers asked the airlines if the event had been observed. .
