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…
Simple answer is Jupiter doesn’t have enough mass to fuse hydrogen into helium. But you didn’t come here for the simple answer! This process of turning hydrogen into helium is known as nuclear fusion and it is the energy source that powers the sun and most other stars. What drives nuclear fusion? For nuclei 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…

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…
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.

Article by Armagh Astronomer Tolis Christou Imagine being outdoors on a sunny day, following the Sun as it rises from the east, heading towards the south and then on towards the west where it sets. Now think back: when did you feel the hottest: when the Sun was highest in Read more…
Here we are, on the count down to Christmas, and we’re having a look at all the Astronotes that have been written for our blog this year. We’ve had input not just from the Education Team this year, but also the Academic Staff of the Armagh Observatory and Planetarium.
The discovery of planets orbiting around other stars has been one of humankinds greatest achievements. The existance of these ‘exo-planets’ can challenge our perception of our place in the universe. Since the first confirmed detection of a planet around another normal star (51 Peg) in 1995, many thousands of planets have been discovered. Indeed, it is likely that most stars will have their own system of planets. It is important in answering the question – is there intelligent life out there?
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.
Space is always changing. New things are discovered frequently, and the latest discovery was made inside our own solar system. Jupiter, the largest planet in our solar system, now has a staggering 79 moons in its orbit. Compare this to Earth’s lonely, singular moon and this shows you just how monstrous the gas giant planet is in size.
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…
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…
Star Wars, the very name brings up images of childhoods spent in front of a TV or cinema screen, absorbing up stories of a galaxy far, far away. For many, it was the thing to ignite their passion for storytelling, and for others it was the thing that ignited their Read more…
October is over, and November is now upon us. The days are definitely getting colder, the night are definitely longer, which means the time for gazing into the night sky is now! One of the best things about November is the fact that there is not one, but two meteor Read more…
It is common knowledge that the Earth is running out of resources, we’re constantly plagued with images and statistics supporting renewable energy and changing our way of thinking but what if we gathered resources from Space and gave the Earth a break from human pillaging? This is an idea from Read more…
As the summer draws to a close September is a perfect time for stargazing before the cold nights of winter finally creep in. With sunset around 9pm and a forecasted heatwave, fingers crossed for some clear skies with some lovely mild temperatures. A key feature of the summer night sky Read more…
It’s hard to believe that the summer has come around and we are half way through 2017. Time may be flying by but the good weather means a chance of clear skies at night and with lots to see this month let’s hope the rain stays at bay. Read more…
The spring night sky has well and truly sprung, and although these months are sign of brighter evenings and therefore later bedtimes if you want star gaze, there are still lots of interesting patterns and objects that we can see. So let’s delve in and find them. The spring night Read more…
The discovery of the TRAPPIST-1 exo-planetary system is a truly remarkable event in science. It is an exemplar of how an armada of telescopes – some located on the ground and some in space, and collectively owned by a league of nations – can work together to chart new frontiers Read more…

As a species we human beings are rather obsessed with the end of our world and how that is going to happen. From zombie apocalypses to giant asteroids hitting the Earth, we’ve pretty much thought of everything. However there is a new idea in town, and it makes giant asteroids Read more…
It’s the middle of May! Let’s go out tonight and look at the stars! At this time of year in the UK and Ireland, our nights are getting later and shorter, partly due to our planet’s axial tilt and partly due to daylight savings time, with the Sun setting soon Read more…
See you later February, you’ve been a wonderful month, but now it is time to welcome March. Something we delight in here at Armagh Planetarium is how the months got their names. March is a particularly nerdy one. March got its name after the Roman god of war, Mars. Not Read more…
