See the Moon and Saturn get close at dusk on 17 September

16 September 2018 Ade Ashford

Skywatchers in the UK looking to the south-southwest at dusk on Monday, 17 September can see the waxing gibbous Moon just 1¾ degrees to the upper left of Saturn, the pair fitting comfortably in the same field of view of binoculars and small telescopes magnifying 25× or less. This is also a good night for spotting Titan, Saturn’s largest and brightest moon.

Watch asteroid 2015 FP118 fly by Earth in early September

31 August 2018 Ade Ashford

Shortly after 11am BST on Monday, 3 September, an 800-metre-wide space rock with the catchy name 2015 FP118 hurtles past Earth some 12¼ times the average distance of the Moon. On subsequent nights we show you how to track it down with backyard telescopes of 10-inch (25-cm) aperture and larger.

Observing

See bright Comet 21P’s close brush with conspicuous Capella

27 August 2018 Ade Ashford

If you’ve never seen a comet, there’s currently a bright example visible in the late evening about to make a close approach to the 6th brightest star in the night sky on the UK night of 2–3 September. We show you how to find Comet 21P/Giacobini-Zinner around the time it passes within a degree of prominent star Capella.

See the Moon meet the Red Planet on the UK night of 23 August

23 August 2018 Ade Ashford

Mars may be almost four weeks past opposition, but it’s still an imposing sight low in the southern sky around local midnight. But if you are in any doubt about identifying the Red Planet, the waxing gibbous Moon acts as a convenient celestial guide late into the UK night of Thursday, 23 August. See both the Moon and the Red Planet in the same field of view of low-power binoculars.

Observing

See innermost planet Mercury’s favourable dawn show

22 August 2018 Ade Ashford

Mercury attains its maximum westerly elongation from the Sun on 26 August, meaning that the innermost planet is currently well placed for observation from the UK and Western Europe in the eastern sky around 40 minutes before sunrise. In addition to those in the evening sky, you might just see all five bright naked-eye planets this month!

Observing

Don’t miss 2018’s favourable Perseid meteor shower, 12–13 August

3 August 2018 Ade Ashford

From the UK evening of Sunday, 12 August into the early hours of the following morning it’s the maximum of the annual Perseid meteor shower. This year, a new Moon setting in twilight makes prospects for watching this natural firework display particularly good. So, find somewhere away from the streetlights, settle into a garden lounger facing northeast and enjoy the show!

Observing

See the Moon join a midnight planetary parade from 21–28 July

19 July 2018 Ade Ashford

If clear skies persist, observers in the UK can view four naked-eye planets between now and the end of the month. Brightest planet Venus is visible low in the west some 45 minutes after sunset, while the waxing Moon is your celestial pointer to Jupiter, Saturn and Mars between 21 and 28 July at midnight.
