Jupiter has passed opposition, but the solar system’s largest planet is still putting on a magnificent show in the southern sky at dusk. Backyard telescopes readily reveal its Great Red Spot storm feature and four main moons constantly playing tag. Here’s our full guide to Jovian events visible from the UK in June.
Skywatchers in Western Europe looking at the rising 13-day-old gibbous Moon in the south-southeast at dusk on Sunday, 27 May can also see prime-time Jupiter within the same binocular field of view. But look closer in the vicinity of the solar system’s largest planet and you’ll see an easily resolved double star – alpha Librae.
With the opposition of Jupiter occurring on 9 May, now is the time to ensure that your telescope is clean and collimated (aligned) to deliver the sharpest images of the solar system’s largest planet at its best. We tell you when and how to view Jupiter’s Great Red Spot and a wealth of Galilean moon phenomena throughout May 2018.
Observers in Western Europe looking at the rising full Moon low in the southeast on the night of Monday, 30 April will also see conspicuous planet Jupiter close by, the pair fitting comfortably within the field of view of typical binoculars. Jupiter is close to opposition (9 May) and we show you how to identify its four main moons.
Jupiter, the solar system’s largest planet, is now visible low in the southeast three hours after darkness falls in the UK. Now’s the time to dust off your telescope, check its optical alignment and hone your Jovian observing skills – particularly since a series of double shadow transits of the planet’s large Galilean moons starts on 24 March 2018.
It currently pays to be an early riser if you wish to view the planets, for it’s all happening at dawn in the skies of Western Europe. Find innermost planet Mercury, see a near miss of Mars and Jupiter on 7 January, then a fabulous binocular conjunction of the waning crescent Moon, the Red planet and Jupiter on 11 January!
Despite more than seven weeks having passed since opposition, the Solar System’s largest planet Jupiter is still big and bright in the UK evening sky of May, highest in the south around 10pm BST. Find out about the phenomena of Jupiter and its moons that you can see from the British Isles for the remainder of the month, starting with a transit of Jupiter’s Great Red Spot on 19 May.
Around 6:30am GMT on Friday 25 November, as nautical twilight starts for the centre of the UK, the 25-day-old waning crescent Moon lies just 2½ degrees away from largest planet Jupiter low in the southeastern sky. This juxtaposition of the two brightest objects in the dawn sky will be nicely framed in a typical binocular.
UK observers with a clear sky an hour before sunrise on Friday 28 October should look very low in the east-southeast to see the slim crescent of the 27-day-old Moon less than four lunar diameters away from largest planet Jupiter. The Moon and Jupiter are also joined by third-magnitude double star gamma (γ) Virginis, commonly known as Porrima.
