Star-gazers are in for a treat over Christmas, as Jupiter and Saturn will get closer to each other in Earth’s night sky than they have been for nearly 800 years. Set up your telescope, hope for a clear night, and get ready.
The celestial synchronisation has been in the works since summer as Jupiter and Saturn have been moving closer together in the night sky, and between 16-25 December they’ll be separated by only 1/5th the diameter of a full moon.
