Once more, scientists have provided the answers. This time they have revealed what the mysterious 'explosion' sound from a 'UFO' was.
The previously unexplained sound was heard by many New England residents for a staggering 12 seconds on 20 October.
It wasn't just the sound that freaked locals out though, as the event saw homes shaking and windows shattering.

Since that cold October day, scientists have been trying to work out exactly what caused the 'strange' noise to provide answers to concerned residents.
Initially, Harvard University was tasked with finding some answers, with the establishment's astronomical instruments recording the noise.
It quickly discovered the noise did not resemble anything from birds, aircraft or wind.
So, Harvard's former head of astronomy and an apparent alien-hunting physicist Avi Loeb was tasked with finding the source of the noise that freaked so many people out.

Loeb quickly discovered the sound was moving at 1,115 feet per second, as captured by an observatory in Cambridge, Massachusetts.
From that, the expert determined the energy source likely came from an exploding mile-wide meteor during the recent Orionid shower that peaked in the New England area a day after the 'strange' sound.
Thankfully, the rather loud noise was recorded using a massive, ultra-sensitive microphone installed on the building of Harvard.
Andy Mead contacted Loeb on 21 October after picking up the sound on the the handy piece of tech he designed and constructed.

Mead shared in a note: "I started getting messages this morning about a 'viral' sound that was heard throughout New England.
"Notably, the Mount Washington Observatory made a post about it as they had so many inquiries.
"That post now has over 4,000 reactions, 1,000 comments, and 751 shares, many of whom heard the sound and are following the story."
Loeb created a website next to crowdsource reports from other locations that could hopefully determine the distance of how far this mystery source had travelled.

"Given the mission of the Galileo Project, one question came to mind: 'Is this an Unidentified Anomalous Phenomenon (UAP)?' Are aliens using advanced technologies near Earth,'" he shared with Medium.
Loeb added: "Multiplying this speed by the duration of the pulse, 12 seconds, implies a shell width of 4 kilometers for the blast wave, implying a distance of about 40 kilometers from the explosion.
"At that distance, the measured pressure disturbance suggested an explosive energy release of 2.4 kilotons of TNT. The inferred energy and distance are reminiscent of meteors, which are known to make their own music at high altitudes."
