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.
On Saturday 27 August at 22:32 UT (11:32pm BST), a spectacularly close conjunction occurs between Jupiter and Venus just 22 degrees west of the Sun in the constellation of Virgo, when the planetary pair are just 4 arcminutes, or one-fifteenth of a degree, apart. Here is our guide to the best locations and times to view this rare event.
If the excitement of the Juno spacecraft’s arrival at Jupiter has prompted you to seek out the solar system’s largest planet, then the 5-day-old cresent Moon acts as a convenient celestial guide during the evening of Saturday, 9 July when it makes a close pass of the gas giant. Here’s our guide to where and when to see this beautiful celestial pairing.
As dusk fades to dark on Saturday, 11 June, observers in the British Isles should look low in the western sky to see the 7-day-old waxing crescent Moon and Jupiter less than 3 degrees apart, within the same binocular field of view. Get your observations in now as the solar system’s largest planet is poised to leave the celestial stage during the summer.
Now two months past opposition, the solar system’s largest planet, Jupiter, is highest in the UK sky before sunset and is already descending in the southwest by the time the sky is dark enough to observe it. However, there is still phenomena of the Galilean moons to see and the planet’s Great Red Spot, so make the most of your Jovian observations while you can during May.
