Catch Venus near bright star Spica in the dawn sky

12 November 2018 Ade Ashford

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.

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

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.

See the young crescent Moon meet Venus at dusk on 18 April

18 April 2018 Ade Ashford

Observers in Western Europe should try to locate Venus low in the western sky an hour after sunset. The 3-day-old slim crescent Moon acts as a convenient guide, located some 12½ degrees (or half the span of an outstretched hand at arm’s length) to the upper left of the brightest planet on 18 April. Prominent star Aldebaran lies in the same low-power binocular field of view as the Moon too.

Mercury attains a greatest easterly elongation of 18 degrees from the Sun on 15 March, the innermost planet’s best evening showing for Northern Hemisphere observers for the entire year. From 12–20 March, planets Mercury and Venus remain just 4 degrees apart low in the west 45 minutes after sunset as seen from the British Isles.

See Venus and Jupiter get close at dawn on 13 November

10 November 2017 Ade Ashford

At the beginning of civil twilight on Monday, 13 November, observers in Western Europe and the British Isles should seek out a viewing location offering an unobstructed view very low to the southeast horizon to see brightest planet Venus and largest planet Jupiter separated by little more than half the width of a full Moon.

See the old crescent Moon meet Venus at dawn on 18 October

17 October 2017 Ade Ashford

Observers in the British Isles and Western Europe should look low to the east about an hour before sunrise on Wednesday, 18 October to see the slim crescent of a very old Moon close to the brightest planet, Venus. Mars is also nearby for the keen-eyed among you, but don’t leave it too late or the growing twilight will drown out the Red Planet.

Observing

See Mercury meet Regulus and Mars near Venus an hour before sunrise

6 September 2017 Ade Ashford

Observers in the UK and Western Europe should find an observing location offering an unobscured eastern horizon an hour before sunrise on Sunday, 10 September to see innermost planet Mercury just 0.6 degrees from Regulus, the brightest star in Leo. Conspicuous planet Venus is your convenient celestial guide to finding Regulus, Mercury and Mars.
