Observers within the UK with clear skies round 1am BST on Tuesday, 21 Could can see Jupiter, the photo voltaic system’s largest planet, simply four levels from the waning gibbous Moon low within the south-southeast. At the moment each the Moon and Jupiter match inside the similar discipline of view of binoculars magnifying lower than 10×, seen in opposition to the constellation backdrop of Ophiuchus, the Serpent Bearer.

The thing is, in fact, a planet – none apart from the photo voltaic system’s largest, Jupiter.

Jupiter’s innermost Galilean moon, Io, is eclipsed by the planet’s shadow at 12:22am, therefore solely the opposite three – Europa, Ganymede and Callisto – stay on present at 1am (all occasions given in British Summer season Time).
