Observers in the UK with a clear sky at dusk should try to locate Venus low in the western sky an hour after sunset. The 3-day-old slim crescent Moon acts as a convenient guide, located some 12½ degrees (or half the span of an outstretched hand at arm’s length) to the upper left of the brightest planet. Conspicuous star Aldebaran lies in the same low-power binocular field of view as the Moon too. Note that the size of the lunar crescent has been enlarged for clarity. AN graphic by Ade Ashford.Observers in Western Europe should make the most of fine weather to locate Venus low in the western sky an hour after sunset, particularly on Wednesday 18 April when the 3-day-old slim crescent Moon acts as a convenient guide, located some 12½ degrees (or half the span of an outstretched hand at arm’s length) to the upper left of the brightest planet.
Stargazers in the British Isles with a clear sky around 10pm this evening should note the Pleiades (Seven Sisters) forming a right-angled triangle with Venus and the Moon in the deepening twilight, but don’t leave it much later as the brightest planet sets around 10:43pm as seen from the heart of the UK (stated times are in BST).
Prominent first-magnitude star Aldebaran lies in the same low-power binocular field of view as the Moon too. In the small hours of 19 April, the waxing lunar crescent actually occults (passes in front of) Aldebaran as seen from central and northern Russia, north and eastern Scandinavia, the north of Greenland and northernmost Canada.
This new NASA/ESA Hubble Space Telescope image reveals the beating heart of one of the most visually appealing, and most studied, supernova remnants known — the Crab Nebula in the constellation Taurus. At the centre of this nebula the spinning core of a deceased star breathes life into the gas that surrounds it.
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.
Mars may be almost four weeks past opposition, but it’s still an imposing sight low in the southern sky around local midnight. But if you are in any doubt about identifying the Red Planet, the waxing gibbous Moon acts as a convenient celestial guide late into the UK night of Thursday, 23 August. See both the Moon and the Red Planet in the same field of view of low-power binoculars.
