Scientists and people across the world are still panic-stricken as a mysterious booming sound has been witnessed in different places of Middle East, East Midlands, Australia and America and the reason behind the same is yet to be found.
The heart-shivering sound, nicknamed 'Bama Boom', has left experts spellbound and they are working hard to find the reason behind the same.
The latest boom was reported from the US state of Alabama and Idaho in the last week.
"Loud boom heard: we do not see anything indicating large fire/smoke on radar or satellite; nothing on USGS indicating an earthquake," the Birmingham National Weather Service took to micro-blogging site Twitter to share the news to the world."
The boom could have been caused by a supersonic aircraft, a ground explosion, or a bolide, a large meteor that explodes in the atmosphere unrelated to the Leonid shower," Bill Cooke, head of Nasa's Meteoroid Environment Office, was quoted while interacting with ABC 3340.
The noise, which was also picked up by the US Geological Survey, noted that the boom was not the result of an earthquake. The boom may have been caused by a military flight by a supersonic jet, they said, although the US Air Force is yet to confirm this.
The Bama Boom is just one of many mysterious booms heard worldwide this year.
According to some reports, this is not the first time the mysterious sound has been heard. In 2017 alone, 64 booms have been heard worldwide, in locations including Michigan, Lapland, St Ives, Swansea, and Yorkshire.
Re: loud boom heard: we do not see anything indicating large fire/smoke on radar or satellite; nothing on USGS indicating an earthquake. We don't have an answer, and can only hypothesize with you. 1) sonic boom from aircraft; 2) meteorite w/ current Leonid shower?— NWS Birmingham (@NWSBirmingham) November 14, 2017
On October 10, a similar sound left Cairns locals confused. Many suggested it was an FA-18 Hornet plane was heard flying, news.com.au reported.
Two weeks later, another boom was heard over the Eyre Peninsula in South Australia at the same time a blue meteor passed across the sky.
"It just got bigger and bigger and it was just this big flash across the sky and there were sparks coming off it," Port Lincoln local Lisa Watson was quoted by News Corp.
"I pulled up home and I heard two massive bangs, maybe a second apart, and then the sky lit up again I just felt the whole earth shake twice," he added.
According to Cooke, NASA's meteor scientists will continue to analyse new data in hopes of determining the cause of the boom.
