Observers in the UK with a clear sky high to the south-southeast shortly after midnight on Sunday, 12 January 2020 can see the 16-day-old waning gibbous Moon just three-quarters of a degree north of the beautiful open star cluster Messier 44, otherwise known as Praesepe, or the Beehive Cluster. AN graphic by Ade Ashford.If you own a pair of binoculars or a small telescope, you may wish to take a look at the Moon on the night of 11–12 January 2020 since it lies in the constellation of Cancer, the Crab. If you look a little more closely, you’ll see that the Moon lies in the same field of view as the glorious open star cluster known as Praesepe, the Beehive Cluster, or more prosaically as Messier 44.
For observers in the British Isles, the Moon’s orbital motion doesn’t bring it closest to the Beehive Cluster until the calendar clicks onto 12 January, by which time the pair are high in the south-southeast. At their closest – 12:30am GMT (00:30 UT) – the 16-day-old waning gibbous Moon lies just three-quarters of a degree north of the heart of Praesepe. In a telescope, use your lowest magnification eyepiece and watch as the Moon glides over the northern edge of M44, occulting (passing in front of) a number of its fainter stars.
Many will be looking skyward to see terrestrial pyrotechnics this Bonfire Night, but if you own a small telescope and can escape the light pollution, you can see the waning gibbous Moon hide three naked-eye stars in Taurus on the night of 5—6 November, culminating in first-magnitude star Aldebaran in the small hours of Monday morning.
Ten years ago today, on 14 January 2005, a compact, flattened cylinder called Huygens, chock-full of sensors, cameras and scientific experiments, went hurtling through the orange skies of the mysterious moon Titan.
On the night of 19—20 January, the 10-day-old waxing gibbous Moon glides in front of the loose open star cluster known as the Hyades that represent the bull’s head in the constellation of Taurus, culminating in the occultation of bright star Aldebaran an hour or so before moonset for observers in the British Isles.
