While antipodean observers are enjoying views of the totally eclipsed Blue Moon in Cancer the Crab on the night of 31 January/1 February, Northern Hemisphere observers should look out for magnitude +6.9 1 Ceres at opposition in the northern fringes of the same constellation. The dwarf planet puts on a good show in the dark of the Moon during February.
Skywatchers in the UK looking to the south-southeast shortly before midnight on Friday 9 June can see the rising full Moon just 2½ degrees above Saturn, the pair fitting comfortably in the same field of view of binoculars and telescopes magnifying less than 20×. Saturn is closest to the Earth for this year on 15 June, so here is our quick observing guide to the ringed planet at its best.
Jupiter, the Solar System’s largest planet, reaches opposition on the evening of 7 April and lies closest to Earth for 2017 the following night. Don’t miss the 14-day-old Moon passing close by on the night of 10 April too. Here’s our comprehensive guide to what to see on Jupiter and phenomena of its bright moons for the month ahead.
On the evening of Monday, 30 May, Mars is closer to Earth than at any time since 30 October 2005. This begs the question: just how close can Mars get? Ade Ashford gives you an overview of close Martian oppositions past, present and future. Also, Friday, 3 June sees the opposition of Saturn, the other planet visible low in the south around midnight.
On the morning of Sunday, 22 May planet Mars reached opposition in the constellation of Scorpius and is closest to the Earth on 30 May — its best showing in a decade for Southern Hemisphere observers. As seen from the UK the Red Planet will be low in the south at 1am BST, but on nights of good seeing surface detail will be visible in amateur telescopes. Use our interactive Mars Mapper to identify its features.
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.
If you haven’t done so already, now is the time to ensure that your telescope is clean and collimated (aligned) to deliver the sharpest images of planet Jupiter at its best. We tell you the optimal UK times to view the largest planet’s Great Red Spot and multiple shadow transits from its Galilean moons.
