See the Moon join a midnight planetary parade from 21–28 July

19 July 2018 Ade Ashford

If clear skies persist, observers in the UK can view four naked-eye planets between now and the end of the month. Brightest planet Venus is visible low in the west some 45 minutes after sunset, while the waxing Moon is your celestial pointer to Jupiter, Saturn and Mars between 21 and 28 July at midnight.

See ringed planet Saturn at its best in late June

13 June 2018 Ade Ashford

While excitement among planetary observers is growing for the best views of Mars for 15 years (Martian dust storms permitting) in late July, there’s still one prior planetary treat: the opposition of Saturn on 27 June, which coincides with a close lunar conjunction. We show you what to look for in and around the Saturnian system.

Let Saturn be your guide to finding asteroid Vesta at its brightest

8 June 2018 Ade Ashford

Many of you may have tracked down an asteroid with binoculars or a telescope, but have you ever seen one with the naked eye? If not, then June presents you with an opportunity to see the brightest, 1 Vesta, at a close opposition. What’s more, ringed planet Saturn lies close by to act as a convenient guide.

The gift that goes on giving – Cassini at Saturn

16 May 2018 Astronomy Now

Saturn’s rings cast sharp shadows across the planet’s northern hemisphere in a view captured by NASA’s Cassini spacecraft in 2007 at a distance of about 1 million miles, using red, green and blue filters to produce a natural-colour view.

See the Moon get close to Saturn and Mars in the early morning sky

4 May 2018 Ade Ashford

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.
