Professor Mark Sims on the discovery that Beagle 2 made it to the surface

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.

The red planet Mars is destined to become the ringed planet within 40 million years’ time, when its largest moon Phobos is torn apart, according to two scientists from the University of California, Berkeley.

With just a month to go until the 2016 opposition of Mars, the Red Planet is now visible very low in the southeast before midnight for observers in the heart of the UK. Mars and ringed planet Saturn are presently separated by just over 7 degrees — a low power, wide-angle binocular field of view. The waning gibbous Moon passes by on the mornings of 25—26 April.
