Hoping that you’ve been able to enjoy plenty of long summer days and sunshine over the summer period. Perhaps you’re already anticipating with pleasure some cooler evening temperatures and Read more…
Written by Lovisa Redpath, Education Assistant Hello to all you stargazers! As we are now heading into August, this is a great time for you all to look up (depending on weather conditions of course – as we do live in the UK)! We are drifting away from Summer slightly Read more…
A super spectacle is happening in the night sky from this evening and won’t be seen again until 2040. The five planets — known as “naked eye planets” because they can be seen without the use of binoculars or telescopes — are Mercury, Venus, Mars, Jupiter, and Saturn. They will Read more…
While 2020 was in many ways a strange and challenging year for many of us in one way or another, the heavens certainly gave us cause to look up and find some measure of celestial relief. Well there is good news! 2021 will be no different as we can prepare Read more…
Stargazers could spot a bright light in the sky days before Christmas as Saturn and Jupiter will come the closest they have done in hundreds of years, creating what researchers describe as a “spectacular event in the sky” on Monday 21 December – which also happens to be the winter Read more…
So the nights are drawing in and in as we get closer to the festive season, and though Christmas might not be quite the same as usual this year, there’s still plenty to celebrate. One great socially distanced activity you can do is stargazing! It’s outdoors and doesn’t require a group, and so you can easily go out and have a wee look up at the stars – just make sure to wrap up warm at this time of year!
Welcome to October, stargazers! Autumn is well and truly into full swing now. Along with warm coats, changing leaves and Pumpkin Spiced Lattes, October also brings with it the opportunity to get some excellent planet spotting and star gazing time in. With the gradually longer nights it means you can Read more…
The late September and early October nights bring with them a few things; crunchy leaves for evening walks, pumpkin spice lattes for the masses and the best time of year to get planet spotting. There are five – yes, five – planets that are observable with relative ease this time Read more…
We have finally entered the month of September, however if you were to tell me that it was the 200th Day of March, I would honestly believe you. 2020 has been such a bizarre year, one we will never forget, but one thing we can take comfort in, is the fact Read more…
26th June is Kids in Museums ‘Digital Takeover Day’. Here at the Armagh Observatory and Planetarium we wanted to give our young followers a chance to be published in our blog. Read all about their favourite planets below. Thank you to everyone who entered! Mars My favourite planet is Mars Read more…
Now we come to the sixth planet from the sun, with the magnificent ring system, it’s Saturn! It is now the planet with the most known moons! Saturn recently beat out Jupiter in the moons category, even though Jupiter is the largest planet in the Solar system and behaves somewhat Read more…
Martina Glass looks at the morning sky and what treats it has for us! For thousands of years people used the stars to tell stories, mark the changes in seasons and to help navigate, but even with today’s technological advances many people now know less than those early cultures did. Read more…
Hello Stargazers! We are well and truly into spring now (and hopefully we have all recovered from losing that 1 precious hour of sleep when the clocks sprung forward, eh?). The high pressure weather system we have had recently means clear, crisp nights for many of us – excellent conditions Read more…
Welcome to spring! In theory at least – someone should really let our climate know that it’s time to brighten up a little bit. Depending on whether or not you adhere to the meteorological or astronomical definitions of “spring”, it officially began either on 1st March or will begin on Read more…
Ah, the winter night sky, how we love thee. The shorter daytime means even longer to stargaze; if we are lucky here in Armagh we will get some high pressure days leading to crisp, clear, starry nights. So, in the evenings after your Christmas shopping has finished for the day Read more…
The long standing satellite king of The Solar System, Jupiter, has been dethroned – Saturn now has 82 moons to Jupiter’s 79! via GIPHY The new moons were discovered by astronomers at The Carnegie Institution for Science using the Subaru telescope on top of Mauna Kea in Hawaii. According to Read more…
Hello stargazers! We are just past mid-summer; September is looming around the corner but fear not – we have another lovely month of summertime stargazing to enjoy before the sun-soaked (for some) season fades away. Stargazing during August will be best at around 11pm, after you have given your eyes Read more…
Summer’s here! The weather’s heating up and skies will hopefully be clear for a bit of stargazing! There are lots of interesting sights in the sky this July, so while you may have to wait longer for it to get dark, get outside, allow your eyes to adjust and get Read more…
Looking up at the wonders of the night sky is an amazing pastime, and whether you use a telescope or binoculars all you really need is the naked eye, but remember to give your eyes at least 20 minutes to adapt to the dark to ensure that you can see Read more…
This September is a relatively uneventful month (astronomy-wise). Few visible planets, quiet Sun and overall a very poor month for meteor showers.
It’s the beginning of a new month, filled with new exciting events in the night sky. Here is a brief summary of what to expect in the next few weeks.
This July will be a very astronomically eventful month – full of eclipses, bright planets, meteor showers and bright satellite passes. If the weather permits, we will have the opportunity to witness a lot of interesting events in the night sky.
Where do meteorites come from? This question has been occupying the scientific community ever since it was realised that these “rocks from the sky” are, in fact, pieces of other worlds arriving on our planet from deep space. New research done by scientists at the Armagh Observatory and Planetarium in Read more…
Approximately every other star in the Milky Way galaxy is in a ‘binary’ system. These binaries are made up of two stars orbiting around a common centre of gravity. The time taken for the stars in the binary to make one revolution is called the ‘orbital period’. Binaries have a wide range of orbital period. The closest stellar system to the Sun is alpha Centauri which has two stars not unlike our Sun orbiting around one another every 80 years. A third member of the system, Proxima Centauri, which is much smaller red dwarf star, orbits around these two stars once every 10,000 years.
Article by: Yanina Metodieva, PhD student at the Armagh Observatory and Planetarium March has certainly been an eventful month, and now we’re in to April. The Spring has definitely sprung and we’re enjoying the stretch in the evenings, even if it makes stargazing a little trickier. Sure we have to Read more…
Article written by: Heather Alexander Have you ever had a fun night out with friends, or a lazy day in with loved ones, or even just strolled down the street, and asked the question “Who discovered…?” I am the type of person who asks this question, frequently. Thanks goodness I Read more…
Welcome stargazers to that haven where in the midst of our busy lives, between all our comings and goings, we can look up and find solace, and be inspired by the quiet glittering beauties overhead. So let’s start with the summer triangle, discussed in July’s article, and use it as Read more…
Named after a famed 17th Century Italian-French astronomer the Cassini spacecraft took 10 years to reach a distant location in the Solar System, that of Saturn and its surrounding neighbourhood.

It is widely accepted that our Solar System was created about 4.6 billion years ago based on dating of meteorites. Scientists believe the Solar System formed when a cloud of dust was disrupted by the shockwave from the explosive death of a nearby star initiating its collapse into a stellar Read more…
June is finally upon us, and the summer is officially in full swing. The nights may be brighter for longer, but that doesn’t mean that there isn’t some brilliant stargazing to be had. If anything, summer is a wonderful time to go stargazing, as you don’t really need to worry Read more…
