Bright Moon photobombs Geminid meteor shower peak on 14 December

5 December 2019 Ade Ashford

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 between 2h and 23h UT (2am to 11pm GMT) on Saturday the 14th, but its bright and slow-moving shooting stars will have to contend with the glare of a nearby Moon just two days after full.

Don’t miss Mercury in the eastern sky at dawn during August 2019

8 August 2019 Ade Ashford

Mercury attains a greatest elongation 19 degrees west of the Sun late on 9 August 2019, hence the innermost planet is a morning object. This means that early risers in the British Isles with clear skies have several opportunities to view Mercury between the first and third weeks of this month.

Observing

See Mercury and Mars get close at dusk on 18 June

5 June 2019 Ade Ashford

On 18 June at the end of civil twilight in the UK, planets Mars and Mercury lie slightly less than one-quarter of a degree apart in the constellation of Gemini. Observing this conjunction will be a challenge from the UK as the pair will be just 5 degrees high in the west-northwest at civil dusk in bright twilight, which is about 50 minutes after sunset for London.

See Comet Iwamoto’s dash through Leo, Cancer and Gemini before full Moon

10 February 2019 Ade Ashford

Grab your binoculars to catch a glimpse of speedy Comet C/2018 Y1 Iwamoto over the coming week before the glare from a full Moon on 19 February drowns it out. Potentially attaining magnitude +6, the comet passes closest to Earth on 12 February when it can be found traversing Leo at a rate of 7.2 degrees/day. Don’t miss C/2018 Y1’s close enounter with galaxy NGC 2903 on 13 February – by eye, camera, or live online.

A viewing guide to the totally eclipsed supermoon of 21 January

17 January 2019 Ade Ashford

While you may not relish the prospect of waking up in the small hours most Monday mornings, observers in the British Isles and Western Europe will want to set their alarms no later than 5am GMT on 21 January to see this month’s showstopper celestial event — a total lunar eclipse of an unusually close ‘supermoon’. The total lunar eclipse is also visible in its entirety (weather permitting) from the Americas.

Don’t miss the Geminid meteor shower 13–14 December 2018

13 December 2018 Ade Ashford

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.

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.

Observing

See dwarf planet Ceres at opposition on 31 January

26 January 2018 Ade Ashford

While antipodean observers are enjoying views of the totally eclipsed Blue Moon in Cancer the Crab on the night of 31 January/1 February, Northern Hemisphere observers should look out for magnitude +6.9 1 Ceres at opposition in the northern fringes of the same constellation. The dwarf planet puts on a good show in the dark of the Moon during February.

Best ever Geminid meteor shower around 14 December?

11 December 2017 Ade Ashford

Could we be in for a bumper crop of Geminid meteors just before the middle of December? There’s a good chance that we will given that their parent body, the mysterious crumbly “rock comet” 3200 Phaethon, is also making a close flyby of Earth this month.
