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.
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.
A rover and landing platform developed as a backup for China’s Chang’e 3 Moon mission will be repurposed to attempt the first touchdown on the lunar far side by the end of the decade, Chinese officials said.
While looking for Geminid meteors, observers in Western Europe should also look to the southeast about 90 minutes before sunrise to see a beautiful conjunction of a 25-day-old Moon, Jupiter and Mars on Thursday, 14 December.
