See the Moon, Mars and Saturn triple conjunction of 1 March

29 February 2016 Ade Ashford

In the pre-dawn twilight of Tuesday, 1 March, the 21-day-old waning gibbous Moon acts as a convenient celestial guide to planets Saturn and Mars. For observers in the centre of the British Isles, the best time to see this triple conjunction is shortly before 6am GMT, when the trio are highest in the sky to the south.

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).

On the morning of Thursday, 7 January, observers in the UK with a clear sky and an unobstructed view low to the southeast at 7am GMT (central British Isles) can see a close conjunction between the old crescent Moon, Venus and Saturn — all three encompassed by the field of view of a typical binocular.

Some five weeks after opposition, Saturn attains a maximum altitude of just 18 degrees in the south around 10:30pm as seen from the centre of the UK. If you need help finding the ringed planet, the Moon passes conveniently close by on the night of 28 June.

Hubble revisits tangled galaxy NGC 6240

25 May 2015 Astronomy Now

Not all galaxies are neatly shaped, as this new NASA/ESA Hubble Space Telescope image of NGC 6240 clearly demonstrates. Hubble previously released an image of this galaxy in 2008, but the knotted region was only revealed in these new observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys.
