Now that the season of mists and mellow fruitfulness is upon us and the bright summer stars and planets are slipping away to the west, why not seek out some of the spectacular double stars of the autumn sky? We show you how to find some celestial gems suitable for small to medium telescopes in the constellations of Aquarius, Aries and Andromeda.
Clear nights of early Northern Hemisphere autumn offer ideal opportunities to track down the two outermost planets of the solar system, Uranus and Neptune. What’s more, you don’t need a big telescope to find them. We show you how to locate these gas giants using binoculars. The Moon also passes close to Neptune on 20 October.
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.
Like buses, you can wait ages for a near-Earth asteroid – then two come along in quick succession. This weekend you also have the opportunity to view a 70-metre-wide space rock known as 2018 RC in backyard telescopes of 6-inch (15-cm) aperture and larger as its hurtles past Earth closer than the Moon.
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.
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.
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!
Barnard’s Star is a familiar name in both the history of astronomy and popular culture, but did you realise that it’s the closest stellar body to the Sun that you can see from the British Isles and similar latitudes? We tell you some fascinating facts about this famous runaway star and show you how to locate it.
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!
