This simulated 10× binocular view depicts the rising 10-day-old Moon in conjunction with Aldebaran and the Hyades star cluster in Taurus at 6pm GMT on Thursday, 17 January 2019 as seen from the heart of the British Isles. The waxing gibbous Moon is less than 1 degree from first-magnitude Aldebaran at this time. AN graphic by Ade Ashford.
As dusk fades to dark on Thursday, 17 January, observers in the British Isles and Western Europe can see the rising 10-day-old Moon less than 1 degree away from first-magnitude star Aldebaran in the constellation of Taurus.

The pairing of the waxing gibbous Moon and Aldebaran will be close enough for them to be seen in the same field of view of telescopes at magnifications of 35× or less, but it is in binoculars where the full beauty of the Moon’s stellar backdrop will become apparent.

Observers with low power, wide-field binoculars will also see the V-shaped Hyades open star cluster in the same field of view. Note that the star field is strewn with interesting wide double stars, particularly in the vicinity of naked-eye pair θ1 and θ2 Tauri.

While it may seem that Aldebaran is a member of the Hyades, it is merely a line-of-sight effect: the orange giant star and its dim red dwarf companion are 65 light-years away, whereas the 300 to 400 stars that comprise the cluster lie some 152 light-years from Earth.

On the morning of Saturday, 9 January — just two days after their photogenic conjunction with an old crescent Moon — planets Venus and Saturn reach the denouement of their pre-dawn show with a spectacular close conjunction. To observe this spectacle you need an unobstructed view low to the southeast around 7am GMT (central British Isles).

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.
