See planet Venus hit peak brightness in the evening sky

13 February 2017 Ade Ashford

Currently setting over four hours after the Sun as seen from the heart of the UK and visible in the west-southwest at dusk, dazzling Venus is about to hit peak brightness in the constellation of Pisces. The planet attains magnitude -4.8 on Friday 17 February — some 21 times the luminosity of brightest star Sirius gracing the southeast horizon as darkness falls.

Dazzling Venus and much fainter Mars have a close encounter with a young Moon in the constellation of Pisces at UK dusk on Tuesday 31 January. The trio form an equilateral triangle small enough to be encompassed by the field of view of a 7x binocular low in the west-southwest for a couple of hours from 7pm GMT.

See Venus farthest from the Sun, in conjunction with Neptune on 12 January

10 January 2017 Ade Ashford

Thursday 12 January brings not only a full Moon, but also finds brightest planet Venus at its greatest easterly elongation from the Sun. By the time darkness falls in Western Europe and the UK, Venus also lies just 0.4 degrees from outermost planet Neptune, while Mars lies less than the span of a fist at arm’s length to their upper left.

The young crescent Moon’s nightly motion from 31 December 2016 to 3 January 2017 carries it past dazzling planet Venus and first-magnitude Mars. A small telescope also reveals outermost planet Neptune, which passes just 0.02 degrees from Mars around 7h UT on 1 January, offering observers around the world a New Year’s Day treat.

For the seventh and final time this year, the Moon occults outermost planet Neptune on Tuesday 6 December. Weather permitting, this event will be seen over a swathe of the Western Hemisphere including the northeastern USA, eastern Canada, Greenland, Iceland and the western British Isles.

Observers in the UK will find Venus almost directly below the three-day-old Moon low in the south-southwest in deep twilight an hour after sunset on 3 December. The pair will fit in the same field of view of most 8x and 7x binoculars, but a deep-sky treat lies in store for telescope users.

Catch Mars and Venus in the early evening sky of late November

25 November 2016 Ade Ashford

Find a location that offers you an unobstructed view of the horizon from south to southwest an hour after sunset. With clear skies, you’ll be able to follow Venus and Mars from night to night on their celestial peregrinations through the constellations of Sagittarius and Capricornus. The two planets almost keep pace with each other throughout the remainder of November.

Recently active lava flows from volcano Idunn Mons on Venus

19 October 2016 Astronomy Now

Planetary researchers at the German Aerospace Center (DLR) have pushed the limits of the data resolution from ESA’s Venus Express spacecraft. With this new technique, analysis of the top and eastern flank of 200-kilometre-wide volcano Idunn Mons in the southern hemisphere of Venus revealed an indication of geologically recent volcanism in this area.
