Puzzled! The astronomers photographed three UFO lines flying across the moon. Overseas network April 28, an amateur astronomer has recently uploaded a puzzling video through social networking. From the picture we can see 3 UFO lines skimming over the moon. The video sparked heated discussions between netizens and UFO experts. For a time, helium balloons, meteors, birds and even extraterrestrials came in. According to the daily mail of London, the puzzling video is captured by 4K camera. Up to now, it has been watched more than 6000 times. The video shows only half the moon, but its ringed mountain is clearly visible on cloudless night. With 3 strange saucers flying past, the picture slightly shook. The user said, I photographed half a moon on Sunday, and then found some strange things flying over. Two objects seem to be very close, and the third objects are slightly behind. This video has triggered a variety of guesses. The report said conspiracy theorists thought they might be extraterrestrial objects, and the users who released the video speculated that the 3 mysterious objects were just balloons, while others believed they might be meteors, satellites or birds. In a video description, the uploads said, in 1 minutes and 18 seconds, there were 3 objects that were flying over the moon. I think it was a helium balloon put by someone, but Im not sure. Some people think that from the shape or the space stone, the object flying below and on the right seems to be the shadow of some object. Is it a meteor? But some people questioned and believed that the UFO displayed in this strange video could be an alien, if the video is true, I dont think these are helium balloons. Why would someone put 3 balloons and send them near the orbit? (if it is a balloon) they have the possibility of bumping together, and they have to be close enough to the moon to show a shadow on the surface of the moon. It must be something else. UFO experts and investigators say, I dont think its a satellite, asteroid, and space garbage. I think its a bird image that flies from between the camera and the moon. Because they are lined up, and when they appear, the picture appears slightly shaking, which is probably flapping their wings.
