More Jupiter events to enjoy in August 2019

31 July 2019 Ade Ashford

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.

Further Jupiter events for UK observers in July 2019

28 June 2019 Ade Ashford

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.

Get ready for prime-time Jupiter and its multi-moon events in June 2019

30 May 2019 Ade Ashford

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.

See the Moon and Jupiter get close in the small hours of 21 May

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.

See the waning Moon meet Jupiter and Saturn at dawn, 27–29 March

25 March 2019 Ade Ashford

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.

Last week, we posted a dramatic view of Jupiter’s churning clouds as recently seen by NASA’s Juno orbiter. Here is another mesmerising JunoCam view of the solar system’s largest planet with the volcanically tortured moon Io rising above the horizon in the black of space.
