A strange, jellyfish-shaped object has been filmed hovering in the sky near a US military base before seemingly vanishing within minutes.
Sara Jane Osborn was taking photographs of a rainbow in Anchorage, Alaska, when she spotted a dark shape rising above distant trees.
She believes the object was near Joint Base Elmendorf-Richardson (JBER), which is home to F-22 Raptor fighter jets and supports air defence and surveillance operations.
The sighting happened at around 10.13pm on June 15, while the sky was still bright.
At first, Osborn thought the object might be an insect in the way of her camera.

‘I was annoyed, because I was like, is that a mosquito?’ she told the Daily Mail.
But when she looked beyond her phone screen, she realised the shape was much larger than she had first thought.
She alerted her husband, Pete, who was with her, and began taking photographs and recording the object.
Osborn said it appeared to have several dangling appendages which moved independently as it hovered and turned from side to side.
She estimated it remained visible for around three minutes before disappearing almost as suddenly as it had appeared.
‘It disappeared almost as quickly as it came,’ she said.
The couple were also puzzled by its apparent size, particularly after spotting a small aircraft nearby which looked tiny in comparison.
They searched the area afterwards but said they could not find a kite, anyone controlling one or another obvious explanation for what they had seen.

Osborn said: ‘Only God and the government’ would know what the object was.
This comes after people in Wiltshire and Gloucestershire became convinced that they saw a Jellyfish UFO in 1989.
The UFO was, according to a front-page story in the Swindon Star, first seen by drivers along the A46 near Stroud at around 9pm on Friday, February 10.
Witness reports said the object was ‘larger than a helicopter with more lights than a plane’ and zipped around at incredible speeds.
No photographs or video were taken of the UFO, with the paper including an artist’s rendition of the object instead.
