An amateur astronomer from Australia created this stunning time-lapse video of the night sky over the ocean. It shows clouds streaming across the sky, star-spangled heavens and the oscillations of the tide. It took Alex Cherney of Victoria, Australia a year to compile the 30 hours of exposure. In May Cherney took the overall prize at the STARMUS astrophotography competition for this video.
