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.
Scientists analyzing data from NASA’s Cassini mission have discovered that a giant, toxic cloud is hovering over the south pole of Saturn’s largest moon, Titan, after the atmosphere there cooled dramatically.
When 252P/LINEAR passed just 14 lunar distances from Earth on 21 March, the comet was galloping across the far southern sky at a rate of almost ten degrees per day. Now rapidly heading north, 252P finally appears in the predawn UK sky. While moonlight will interfere with current observations, the comet is much brighter than predicted.
The maximum of the annual Leonid meteor shower is predicted for 11pm GMT (23h UT) on Monday, 18 November 2019. However, the famously swift, bright Leonids — some leaving persistent trails — will have to contend with the glare of a 21-day-old waning gibbous Moon close by visible from 9:30pm GMT to dawn on the 19th.
