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

Article written by: Prof. Jorick Vink, Armagh Observatory and Planetarium. According to the European Space Agency (ESA) there is a 1-in-625 chance that Asteroid 2023DW, with the size of a Football pitch, can strike Earth on Valentine’s Day 2046. Astronomers around the globe, including those at the Armagh Observatory Read more
Article by: Mark Grimley To make things a little easier for us to stargaze it will be helpful to head out of town for a bit, somewhere with less light pollution will allow us to see more stars. For those who live in the countryside, this should be easier. 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
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.
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”.
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!
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
