This may be an ufo photo. how can i yse that that is an ufo?

two days ago, i was taking photos at balcony at night. Today i decided to take a look of these photos. I insert my sd card to my laptop and started to explore, then i saw the picture i was talking about. Pic is about stars in the sky. Stars, pretty normal. But there is a grey circle at the left side of photo and a light below it . I never realized when i took that picture. I realized on laptop's screen. I belive that can be an ufo(alien spaceship) photo. But there's posibility of that circle shaped thing may be a light ilusi�n. So where should i send this photo for a verification?
