Don’t miss Jupiter’s moons and Great Red Spot during May

19 May 2017 Ade Ashford

Despite more than seven weeks having passed since opposition, the Solar System’s largest planet Jupiter is still big and bright in the UK evening sky of May, highest in the south around 10pm BST. Find out about the phenomena of Jupiter and its moons that you can see from the British Isles for the remainder of the month, starting with a transit of Jupiter’s Great Red Spot on 19 May.

See the Moon meet the ringed planet on 14 May

8 May 2017 Ade Ashford

In the small UK hours of Sunday 14 May, the rising 17-day-old Moon in the southeast lies just 2.4 degrees to the upper-left of Saturn, meaning that the pair will comfortably fit in the same field of view of a typical 10×50 binocular. The ringed planet is now about a month from opposition, so now’s the time to hone your observing skills.

See the Moon and Jupiter get close on 7 May

4 May 2017 Ade Ashford

Observers with a clear sky to the south as darkness falls on Sunday 7 May can see the 12-day-old waxing gibbous Moon and planet Jupiter separated by little more than twice the width of a full Moon. For telescope owners in the UK, this is a night where you can also see Jupiter’s Great Red Spot and the planet’s four large Galilean moons.

Look out for Lyrid meteors around 22 April

21 April 2017 Ade Ashford

If skies are clear between midnight and the first glimmer of dawn this weekend, you may get to see some celestial fireworks from the Lyrid meteor shower. While it may not be the richest of the annual shooting star displays, the Lyrids can deliver a few fireballs and a portion of these medium-speed meteors can leave glowing trains.

Watch asteroid 2014 JO25 brush by Earth on 19 April

17 April 2017 Ade Ashford

A peanut-shaped asteroid almost a mile long known as 2014 JO25 passes within 5 lunar distances of Earth on 19 April — the closest any known space rock of this size has approached our planet since September 2004. We show you how to find this fast-moving potentially hazardous asteroid in small telescopes during the UK night of 19-20 April.

Get ready to view planet Jupiter at its best

4 April 2017 Ade Ashford

Jupiter, the Solar System’s largest planet, reaches opposition on the evening of 7 April and lies closest to Earth for 2017 the following night. Don’t miss the 14-day-old Moon passing close by on the night of 10 April too. Here’s our comprehensive guide to what to see on Jupiter and phenomena of its bright moons for the month ahead.

Observing

See a trio of comets in the April sky

2 April 2017 Ade Ashford

Despite the glow of a waxing Moon, early April is a good time to catch a glimpse of comets 41P/Tuttle–Giacobini–Kresák and C/2015 V2 (Johnson) that are currently circumpolar and visible throughout the UK hours of darkness. And if you’re an early riser, there’s seventh-magnitude C/2017 E4 (Lovejoy) low in the pre-dawn eastern sky too!

Observing

See Mercury at its best in the evening sky

26 March 2017 Ade Ashford

Mercury attains a greatest easterly elongation of 19 degrees from the Sun on 1 April. This solar separation combined with a favourable inclination of the ecliptic to the western horizon an hour after sunset, means that the period 25 March to around 8 April offers the year’s best evening showing of the innermost planet for Northern Hemisphere observers.

Don’t miss brightening Comet 41P riding high in Ursa Major during March

17 March 2017 Ade Ashford

Comet 41P/Tuttle–Giacobini–Kresák orbits the Sun every 5.4 years and will pass through perihelion (its closest point to the Sun) on 12 April 2017. Motoring through Ursa Major at close to 2°/day during the remainder of March, this fascinating comet with a history of dramatic surges in brightness, passes close to Messier 97 and 108 on the UK night of 22 March.
