Brilliant planet Venus attains its greatest elongation almost 47° west of the Sun at dawn in the UK on Sunday, 6 January. Find a location that offers you a view down to the southeast horizon around 7am GMT and you may catch a glimpse of Jupiter too. The planetary duo is currently 14 degrees apart, but drawing nearer for a close conjunction on 22 January.
Although Jupiter close to opposition may be stealing the other naked-eye planets’ thunder, there’s lots more to see if you’re an early riser on the weekend of 5–6 May. About an hour before sunrise finds Mars and Saturn less than the span of an outstretched hand at arm’s length apart in the UK southern sky, with the waning gibbous Moon acting as a convenient guide to each planet on successive mornings.
Set your alarm for 6am GMT if you wish to see three naked-eye planets in the UK dawn sky this week. Find a location that offers an unobstructed view of the horizon from southeast to south and let the waning Moon be your guide to locating Jupiter, Mars and Saturn on successive mornings from 7 to 11 February.
It currently pays to be an early riser if you wish to view the planets, for it’s all happening at dawn in the skies of Western Europe. Find innermost planet Mercury, see a near miss of Mars and Jupiter on 7 January, then a fabulous binocular conjunction of the waning crescent Moon, the Red planet and Jupiter on 11 January!
Using ESO’s Very Large Telescope Interferometer astronomers have constructed the most detailed image ever of a star — the red supergiant star Antares. They have also made the first map of the velocities of material in the atmosphere of a star other than the Sun, revealing unexpected turbulence in Antares’s huge extended atmosphere.
Skywatchers in the UK and Western Europe should cast their gaze low in the southern sky late into the evening of Thursday 6 July to see the 12-day-old waxing gibbous Moon in conjunction with ringed planet Saturn. The pair are separated by just 3½ degrees, nicely framed in a typical 10×50 binocular. For telescope users, the night of 6—7 July is also good for spotting Saturn’s bright moons. We show you what to look for and where.
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.
A hundred days have passed since Mars was closest to Earth this year, but the Red Planet can still be seen in the early evening sky close to the jewel of the solar system, Saturn. If you wish to identify this pair of planets, then a convenient celestial marker in the form of the waxing crescent Moon passes by on the evenings of 8—9 September in the UK and Western Europe.
Observers in the British Isles with a clear sky one hour after sunset on 24 August should find a location that offers an unobstructed view of the south-southwest horizon. Here you will see first-magnitude star Antares in the constellation Scorpius, Mars and Saturn all in a line easily encompassed by low-power binoculars in the bright twilight.
