The December Geminid meteor shower is generally regarded as the richest and most reliable of the major annual shooting star displays. This year the predicted peak occurs close to 12h UT on 14 December, though high rates of activity should be encountered between 8pm GMT on Thursday, 13 December and 5pm GMT the following evening.
Bright Comet 46P/Wirtanen skims past Earth just 30 lunar distances away on 16 December when it could become a diffuse magnitude +3 object almost a degree wide located between the Pleiades and Aldebaran in the constellation of Taurus. Grab your binoculars and find a dark sky location well away from streetlights to enjoy this Christmas comet before the glow from a waxing Moon gets too bright from 17 December.
Observers in the British Isles looking due south close to 6pm GMT on Friday, 7 December will find magnitude +0.1 planet Mars about 30 degress, or a span and a half of an outstretched hand at arm’s length, above the horizon. What you won’t see unless you have binoculars or a small telescope is that magnitude +7.9 outermost planet Neptune lies just one-tenth of a degree from the Red Planet.
The Leonid shower is well known for fast meteors, the brightest of which can leave persistent trains that appear to hang in the air for several seconds. This year’s maximum is predicted for 1am GMT on Sunday, 18 November. With a 9-day-old waxing gibbous Moon setting around the time of the shower’s peak in the UK, prospects are good.
Find a location that offers you an unobstructed view of the southeast about an hour before sunrise in the UK over the next week to see dazzling Venus close to the horizon. Look carefully at the planet around 6:30am GMT on 15 November and you’ll see it close to first-magnitude Spica, Virgo’s brightest star.
Skywatchers in Western Europe looking in the southern sky at dusk on Thursday, 18 October can see the 9-day-old waxing gibbous Moon close to the upper left of Mars, the pair fitting comfortably in the same field of view of typical binoculars. This is also a good night for spotting some prominent martian features telescopically – seeing permitting!
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.
