There’s a lot of planetary activity in the dawn sky in mid-April. If you’re an early riser in the British Isles, let the waning crescent Moon be your guide to the naked-eye planets Jupiter, Saturn and Mars on 15 and 16 April 2020. Typical 7×50 or 10×50 binoculars will show these attractive conjunctions well, while the smallest of telescopes also reveal some of Jupiter’s bright Galilean moons.
Jupiter is two months past opposition on 10 August, so you need to be looking low in the southern sky of the British Isles around sunset if you wish to catch the solar system’s largest planet at its best. If you time it right and the weather obliges, Jupiter’s Great Red Spot makes multiple appearances while the planet’s Galilean moons play hide and seek. Welcome to our August 2019 Jovian observing guide.
July opens with Jupiter three weeks after opposition, but the largest planet is still putting on a fine show as an unmistakable magnitude -2.6 object low in the south before midnight in the constellation of Ophiuchus (the Serpent Bearer). With ongoing developments in the Jupiter’s Great Red Spot and plenty of phenomena occurring with the planet’s large Galilean moons, here’s our Jovian observing guide for July 2019.
Jupiter, the solar system’s largest planet, reaches opposition on 10 June in the constellation of Ophiuchus (the Serpent Bearer) and is visible low in the southern sky of the UK through the night. Observers with small to medium aperture telescopes can see a number of shadow transits of Jupiter’s Galilean moons and view the planet’s Great Red Spot throughout June.
Observers in the UK with clear skies around 1am BST on Tuesday, 21 May can see Jupiter, the solar system’s largest planet, just 4 degrees from the waning gibbous Moon low in the south-southeast. At this time both the Moon and Jupiter fit within the same field of view of binoculars magnifying less than 10×, while telescope users can also view Jupiter’s Great Red Spot.
For lunar and planetary enthusiasts, the only naked-eye planet of the evening sky is distant and tiny Mars in the constellation of Taurus. But if you’re prepared to be an early riser, the dawn sky is where you’ll find two of the solar system’s heavyweights, Jupiter and Saturn, getting up close with the Moon on 27 and 29 March, respectively.
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.
