See the young Moon meet the gas giants at dusk, 3–5 October

1 October 2019 Ade Ashford

Skywatchers in Western Europe and the UK should look low to the south-southwest at nautical dusk on 3 and 5 October 2019 to view the waxing Moon pass close to Jupiter and Saturn, the Solar System’s largest gas giant planets. Observers at northern temperate latitudes should make the most of any opportunities to view these planets before they are lost in twilight.

View the International Space Station at its best from the UK

28 September 2019 Ade Ashford

If you have never seen the International Space Station (ISS), make the most of clear skies over the next few nights. It’s capable of exceeding Venus at its brightest and visible for up to 7 minutes as it crawls across the sky in an arc from west to east. Find out when and where to see some favourable passes of this 420-tonne, 109-metre-wide spacecraft over the British Isles and Western Europe.

Watch Comet Africano (C/2018 W2) pass closest to Earth in late September

23 September 2019 Ade Ashford

At around magnitude +9, C/201 W2 (Africano) is the brightest comet currently on show, passing closest to Earth on 27 September slightly less than half an astronomical unit away. Speeding through the constellations of Pegasus, Pisces and Aquarius, Comet Africano also lies within a binocular field of view of outermost planet Neptune on the night of 3–4 October.

Observing

Watch the crescent Moon graze a double star at dawn on 27 August

26 August 2019 Ade Ashford

Depending on where you live in the British Isles, you may be fortunate to view a lunar occultation of naked-eye double star delta (δ) Geminorum at dawn on Tuesday, 27 August 2019. Observers fortunate enough to lie on the so-called graze line will see the star appear to flicker on and off as the mountains and valleys of the northern lunar polar regions drift by.

Observing

See the Moon hide a trio of Hyades stars at dawn on 24 August

20 August 2019 Ade Ashford

Have you ever seen the Moon hide a star? If you’re an early riser in the UK with a small telescope on Saturday, 24 August 2019 then you can potentially witness the disappearance and reappearance of three naked-eye stars in the Hyades open star cluster of Taurus between 3:40am BST and shortly after sunrise.

Observing

A fine Perseid meteor shower peak on 13 August despite a waxing Moon?

9 August 2019 Ade Ashford

It’s the time of year when Northern Hemisphere skywatchers turn their attention to the Perseids, the favourite meteor shower of many an observer. The peak of the Perseids is predicted for moonset on 13 August 2019, bringing dark skies to watch these bright, fast shooting stars — the more explosive examples leaving persistent trails in the sky.

Observing

Don’t miss Mercury in the eastern sky at dawn during August 2019

8 August 2019 Ade Ashford

Mercury attains a greatest elongation 19 degrees west of the Sun late on 9 August 2019, hence the innermost planet is a morning object. This means that early risers in the British Isles with clear skies have several opportunities to view Mercury between the first and third weeks of this month.

Observing

More Jupiter events to enjoy in August 2019

31 July 2019 Ade Ashford

Jupiter is two months past opposition on 10 August, so you need to be looking low in the southern sky of the British Isles around sunset if you wish to catch the solar system’s largest planet at its best. If you time it right and the weather obliges, Jupiter’s Great Red Spot makes multiple appearances while the planet’s Galilean moons play hide and seek. Welcome to our August 2019 Jovian observing guide.

Seek out some fine summer multiple stars

28 July 2019 Ade Ashford

Observers in the British Isles can rejoice that summer astronomical twilight all night is drawing to a close. But if Jupiter and Saturn are currently too low to view, you’re blighted by light pollution, or moonlight robs you of nebulae, why not seek out some of the many beautiful double and multiple stars on show?
