This graphic represents the view due east at 7pm GMT on Christmas Day 2015 as seen from the centre of the British Isles, about an hour after full darkness has descended. The rising full Moon lies in the constellation Gemini, just above magnitude +1.9 star γ Geminorum, otherwise known as Alhena. This is the first time since 1977 that a full Moon has fallen on 25 December and the next time it occurs is 2034, so hopefully it will be clear! AN graphic by Ade Ashford.December’s full Moon, the last of the year, is called the Full Cold Moon because it occurs during the beginning of winter. The instant that this month’s full lunar phase will occur is 11:11am GMT and it will rise at 4:32pm GMT as seen from the centre of the British Isles.
As you gaze up at the Christmas Moon, take note that NASA has a spacecraft currently orbiting Earth’s only natural satellite. NASA’s Lunar Reconnaissance Orbiter (LRO) mission has been investigating the Moon’s surface since 2009.How the Moon will appear on 25 December 2015.

LRO has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the Moon.
Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, six or more years of data from NASA’s Fermi Gamma-ray Space Telescope has broadened the mission’s dark matter hunt using some novel approaches.
On 17th March 2013, an object hit the Moon’s surface in Mare Imbrium and exploded in a flash of light nearly 10 times as bright as anything ever recorded before. NASA’s Lunar Reconnaissance Orbiter has found the new 19-metre-wide crater plus more than two-dozen others.
Comet Lovejoy lived up to its name by releasing as much ethyl alcohol as in at least 500 bottles of wine every second as well as a type of sugar into space during its peak activity, according to new observations by an international team. The finding adds to the evidence that comets could have been a source of the complex organic molecules necessary for the emergence of life.
