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,

While Venus and Saturn are expected to appear bright in the dark sky and can be seen with the naked eye, binoculars or a telescope may help when looking for the ‘smirking moon’ details.
