Welcome to another edition of the night sky for the month of June! If like me you’re glad to have finally shaken off the coldest of this year’s weather to date -then the thought of some comfortable longer periods of stargazing in balmier temperatures has particular appeal. If on the Read more…
Armagh is a partner in two telescope projects whose key goal is to detect the optical counterpart of colliding massive dead stars. Albert Einstein predicted that when two massive objects spiral around each other, eventually merging to become one more massive object, gravitational waves would be emitted. Scientists spent a Read more…
“April is the kindest month. April gets you out of your head and out working in the garden.” – Marty Rubin, Author. It is Springtime, and I’m sure we are all very glad to see the back of winter. With a shockingly cold start to March, here is hoping that Read more…

Finally, we have left the January blues behind us, the month that never seems to end and it is now time for February fun! The chill in the air has well and truly settled in and it looks like it will be staying with us for a while yet.
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.
Our view of the cosmos is biased by the vista that is apparent to our eyes. This is what the view in what we call the optically visible portion of the spectrum. To the unaided eye it is a view of a universe full of stars, together with five planets, one Moon and of course the Sun. When augmented with a telescope, our eyes can then see a universe full of galaxies – giant cities of stars.
Article written by: Helen McLoughlin, Education Officer Let’s face it, New Year’s Resolutions like ‘I’m going to the gym three times a week’ or ‘I’m going on a diet’ are all well and good but fizzle out after a week or two. Why not take up stargazing once a month Read more…
The long cold dark nights have well and truly settled in, and now that it’s December it’s officially acceptable to say the C word. Christmas, Christmas is coming! And so is Santa Claus! Decorations are going up, there’s mad panic to buy Christmas presents and families are organising who’s having dinner and where. Ahh I love this time of year.
With Space Exploration comes theories and conspiracies. In our latest blog we debunk some of the more infamous ones.
NASA has announced the retirement of the Kepler spacecraft. After launch in March 2009, it began a continuous observation of a 115 square degree field of view (the diameter of the moon is 1/2 a degree) between the constellations Cygnus and Lyra.
October is over and the nights are drawing in. Instead of lamenting the fact that we are driving to and from work in the dark, let’s think of the positives – more time to stargaze! And there’s plenty of interesting objects and constellations to look out for in November.
As an earlier Astronotes article reported on, during its XXX General Assembly in Vienna, held in August 2018, the International Astronomical Union (IAU) put forward a draft resolution to rename the Hubble law as the “Hubble–Lemaître law”. The resolution was proposed to recognise Lemaître’s research on the expansion of the Universe, and to pay tribute to both Lemaître and Hubble for their fundamental contributions to the development of modern cosmology.
The Daniel K. Inouye Solar Telescope (DKIST) is under construction on the summit of Haleakalā on Maui, Hawaii. Since DKIST will be observing the Sun’s corona, the sky above the telescope needs to be as free of dust, aerosols and pollutants. The isolated islands of Hawaii provide optimal conditions for clear, “coronal skies”.
After a special vote in the IAu General Assembly, we interview Armagh Observatory and Planetarium Director. Professor MIchael Burton, on the renaming of the Hubble Law.
The Armagh Observatory has been a staple feature along the Armagh skyline since its creation in 1790. Astronomical research has been undertaken within the organisation since the 1790s and to this day it has seen several different Directors and numerous astronomers walk through its historical doors.
Armagh Observatory, 3rd August 2018: Armagh Observatory reports that July 2018 was much warmer and sunnier than average, with only slightly less than average total rainfall. The mean temperature was 17.0 degrees Celsius (62.6 Fahrenheit), approximately 2.2 C warmer than the long-term (1796–2010) average July temperature at Armagh and 1.2 C warmer than the most recent (1981–2010) 30- year average. This was the warmest July at Armagh for five years. The warmest day (highest maximum air temperature) was 27.1 C, which occurred on the 4th, followed by 26.7 C on the 22nd. Both these maxima wereslightly more than 80 degrees Fahrenheit. The coldest day (lowest maximum air temperature) was 14.4 C on the 11th. The coolest night (lowest minimum air
temperature) was 7.6 C on the 10th, and the warmest night (highest minimum air temperature) was 16.6 C on the 27th followed closely by 16.5 C on the 23rd. The minimum grass temperature was 0.3 C on the 10th, so there were no ground or air frosts.
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!
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…
This summer experience our world and beyond as you sit back and relax in the Planetarium’s 360-degree dome theatre. With six different shows running Monday-Saturday throughout July and August there is so much to choose from, including a brand new film.
Article by Jorick Vink , Astronomer at the Armagh Observatory and Planetarium When you are fortunate enough to have a clear view of the night sky, and you start wondering about the properties of all these sources of light, you might be amazed to find out all these stars have Read more…
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: Professor Michael Burton, Director of Armagh Observatory and Planetarium The city of Armagh lays claim to a remarkable history that belies its small size.
