The Moon, Venus, and Saturn are expected to briefly align into a rare formation resembling a "smiley face" this week, Nasa has said. Skygazers will be able to see the two planets and the crescent Moon align into a grin that could last about an hour in the early hours of Friday,

Stargazers will be treated to a rare sight this week as Venus, Saturn and the Moon align to create a “smiley face” formation in the night sky. This rare alignment will be visible for about an hour at around 5.
