In a video, said to be of Comet NEOWISE from Italy rising over the Adriatic Sea, the comet is seen rising through a foreground of bright and undulating noctilucent clouds, with distant stars in the background.
According to the US National Aeronautics and Space Administration (NASA), Comet NEOWISE has remained unexpectedly bright so far, with its ion and mud tails found to emanate from a nucleus about five kilometres in diameter. The comet, which was discovered in late March, has an orbital period of 6,776 years.
