Get ready for multiple shadow transits of Jupiter’s Galilean moons

23 March 2018 Ade Ashford

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.

Three naked-eye planets – Mars, Jupiter and Saturn – grow in prominence in the dawn sky this month. If you wish to identify them for yourself, let the waning Moon be your celestial guide from 7–11 March. We also show you what to look for in binoculars and telescopes.


First close up Juno images of Jupiter’s Great Red Spot reach Earth

12 July 2017 William Harwood

Two days after NASA’s Juno spacecraft streaked over Jupiter’s Great Red Spot, pictures of the solar system’s largest, most powerful storm, have been transmitted to Earth, giving eager scientist close-up views of the 10,000-mile-wide anticyclone where 400-mph winds have been howling for at least 187 years and possibly much longer.


First quarter Moon meets Jupiter and Spica in the evening sky

30 June 2017 Ade Ashford

Observer’s in the UK and Western Europe should look low to the southwest an hour after sunset on Friday, 30 June to glimpse the almost first quarter Moon a low-power binocular field of view to the right of Jupiter in bright twilight. The following night finds the waxing gibbous Moon forming a near isosceles triangle with the planet and first-magnitude star Spica in Virgo.


See the Moon hide double star Porrima then get close to Jupiter on 3—4 June

Jupiter now lies highest in the UK sky at sunset, but the Solar System’s largest planet and its four bright Galilean moons still provide plenty of observable events during June, as we reveal. If you’re uncertain which evening ‘star’ is Jupiter, the Moon conveniently passes by on the night of 3—4 June, a time when European skywatchers can also see the Moon occult (hide) bright double star Porrima.


Don’t miss Jupiter’s moons and Great Red Spot during May

19 May 2017 Ade Ashford

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.


See the Moon and Jupiter get close on 7 May

4 May 2017 Ade Ashford

Observers with a clear sky to the south as darkness falls on Sunday 7 May can see the 12-day-old waxing gibbous Moon and planet Jupiter separated by little more than twice the width of a full Moon. For telescope owners in the UK, this is a night where you can also see Jupiter’s Great Red Spot and the planet’s four large Galilean moons.


Get ready to view planet Jupiter at its best

4 April 2017 Ade Ashford

Jupiter, the Solar System’s largest planet, reaches opposition on the evening of 7 April and lies closest to Earth for 2017 the following night. Don’t miss the 14-day-old Moon passing close by on the night of 10 April too. Here’s our comprehensive guide to what to see on Jupiter and phenomena of its bright moons for the month ahead.


See the Moon and largest planet Jupiter get close on 14 March

12 March 2017 Ade Ashford

Jupiter is now less than a month from opposition (7 April), so it’s very much open season for the Solar System’s largest planet. If you’re unsure where to find it, the rising 17-day-old waning gibbous Moon passes just two degrees from Jupiter on the UK evening of 14 March. Virgo’s brightest star, first-magnitude Spica, makes it a great binocular triumvirate.
