Early this month, when the second supermoon of the year occurred, an amateur photographer waiting to observe the supermoon captured a shooting star bright enough to fill the screen, drawing attention.
According to US Space.com and Newsweek, amateur astronomical photographer Bill Stewart was taking pictures of the sky over West Virginia, USA, around 2 am on the 2nd (local time) to observe the supermoon.
A moment later, he was startled by a sudden roar. A shooting star was falling from the sky with a loud sound.
“The fireball went ‘Pop!’ twice,” said Stewart. “After one bright flash, it split into three pieces. One of these fragments was accompanied by a bright light until it fell to the floor.”
Bill Cook, a researcher at NASA’s Meteoroid Environment Research Office, said, “It was caused by a comet fragment measuring about 30 cm in diameter and weighing about 75 pounds (34 kg) falling to Earth and burning up in the atmosphere.” I would have entered,” he said.
“As the meteor exploded, it released a tremendous amount of energy, which may have caused banging and shaking to some of the locals,” he added. “At its brightest, it was about five times brighter than the full moon.”
The meteor that fell on this day is a ‘fireball’ nicknamed ‘fireball’. It occurs when larger-than-normal meteors fall to Earth, causing strong friction and rapidly burning up in the atmosphere.
“Fireballs are often fragments of rock or ice from asteroids or comets. In particular, in this case, it is likely to be an asteroid,” he said. “There is a possibility that the meteorite remains and fell in the forest between Kentucky and Tennessee.”
