If you are looking for a reason to celebrate then mark 7 February on your calendars as it marks the start of a new year on planet Mars. The year on Mars will be 36. So we thought we would detail some of the differences and similarities between an Earth Read more…
Among my skills as blog editor, podcast host and Education Officer Extraordinaire here at Armagh Observatory and Planetarium, I’m also a fully qualified catastrophizer! That’s right; you give me a senario and I’ll assume the worst possible version of the thing has a very high chance of happening. This came Read more…
We have a number of ‘North Poles’ on Earth. Above shows the sign at the Geographic North Pole. The magnetic North Pole is what your compass points to when you are trying to navigate using it. That is different from the geographical North Pole, which is defined differently. You might Read more…
This week our 5 Facts series continues with our home planet! Read on to learn more about our Earth. Earth is the only planet not named after a God The other planets in our Solar System are named after Roman and Greek Gods, but not our Earth! The word “Earth” Read more…
So as it turns out, we have had a secret, tiny moon lurking around our planet for potentially up to 3 years – and we had no idea! It’s not surprising we missed it – it’s no Europa for sure. It’s so small it is invisible to the naked eye. Read more…
In honour of the UN Climate Summit, we have another article in our series on climate change, Brandolini’s Law: Climate.
Ever been on a walk and noticed rubbish on the side of the road, footpath, on the beach or in a park? Probably. I can’t count the number of times I have. While it might not be the most pleasant thing in the world to pick up other peoples’ rubbish, Read more…
Following from last week’s introduction to our climate change series, this week we have an article explaining how climate change actually works and why it happens. Firstly, we will be drawing on our sister planet Venus as an example. Earth’s Evil Twin Earth and Venus are, on the face of Read more…
Next week, all being well a Falcon 9 rocket will take off from Cape Canaveral in Florida carrying a very special payload: a spacecraft built by a Tel Aviv-based company aiming to be the first privately-funded mission to land on the Moon. The launch follows an announcement, about a year Read more…
21st January 2019, sky-watchers will witness a rare total eclipse of the Moon. This will be the last opportunity to view a total lunar eclipse from the British Isles for three-and-a-half years, until 16 May 2022.
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.
The Armagh Observatory and Planetarium are holding a special event to mark the lunar eclipse, coming at almost the same time as the opposition of Mars. The event has proved so popular that tickets sold out within a couple of hours of being released, so we have written this blog entry to tell you about what will happen if you missed out on obtaining a ticket or are going to try to observe the eclipse from elsewhere.
This article has been inspired by the many questions we get asked here at the Armagh Observatory and Planetarium. We love being asked questions but we thought it would be funny to have a look at the questions you really should never ask an Astronomer. We hope this gives you a bit of a laugh!
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.
The Observatory and Planetarium has welcomed school students to visit for work experience. A previous Astronote described our work with the Faulkes Telescope Project. Below is an account written by three of our work experience students in 2018 March, based on the work done at Armagh Observatory and Planetarium by them and three other students.
Article written by: Conor Byrne As an astrophysicist with a keen interest in space from a young age, the opportunity to witness a rare astronomical phenomenon is naturally quite high on the ‘bucket list’. So when I was attending a research workshop in the United States in August 2017, just 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…
Recent observations of the helium star HD144941 have been obtained from space. Armagh astronomers Professor Simon Jeffery and Dr Gavin Ramsay have discovered that they show a light curve best explained by darker and lighter patches on the star’s surface coming into view as the star rotates with a period Read more…
The 2018 Robinson Lecture will be given by Professor Louise Harra of University College London. Her topic is about the Solar Orbiter, a new spacecraft to be launched to study the Sun. It will be held in the Archbishop’s Palace in Armagh on Wednesday 22 November, 2017, starting at 7pm. Read more…

Technology in this day and age has progressed leaps and bounds over the years and things that may have once been out of reach of the normal everyday person have become more readily available. For instance something as huge and important as the internet, the key to the vast majority Read more…
During the mid-19th century reports of strange motions in the orbits of Uranus and Neptune led astronomers, among them Percival Lowell, to think that perhaps another celestial body was having a gravitational effect on their paths through space. Lowell searched for a mysterious ninth planet until his death in 1916. Read more…
By now interest in Comet C/2012 S1 (Comet ISON) is building. This could be the most dramatic comet in years. Where should we look for this oncoming interloper from deep space? This was a monthly guide aimed at observers in the UK and Ireland to help you find it. As Read more…

In February 2013, the asteroid 2012 DA14 flew past the Earth closer than many of the Earth’s geo-stationary satellites. Although not visible to the naked eye many telescopes were fixed towards the skies in a hope of catching a glimpse of this celestial fly-by. Many other people watched live webcasts Read more…
