Sounding like a trumpet or a collective from a brass section of an orchestra, a selection of videos shot from the Canada to Ukraine, via the U.S., Germany and Belarus show strange goings on above us.

And the eerie sounds have been continuously heard at all different times and locations for almost a decade.

The first video posted on YouTube recording the unusual, unearthly sounds, was in 2008 when a user recorded the strange sounds in the sky from Homel, in Belarus.

That same year another anonymous user shared the 'ear-deafening' sounds that they insisted 'were not a hoax,' from a quiet neighbourhood believed to be in the U.S.

 Kimberly Wookey from Terrace, British Columbia in Canada first captured the alien sound in June 2013, and since then she has managed to capture several recordings of the noise with her most recent being on May 7 this year.
