This month is an interesting one for those of us who love to stargaze. I know the nights are still cooler, so wrap up and head out to watch the stars. While the sun will gradually set later and later until the summer solstice. We will still have plenty of Read more…
Well, time moves on, into another year as we brace for (according to some) the most depressing month of the year. At least we get it over and done with and can enjoy the rest of the year – I am sure it will be a great one… However, January Read more…
We completed a half orbit around the Sun since I wrote the November Night Sky. It felt like yesterday, but it has been 6 months ago. The time is cruel… The days are already quite a bit longer and are still getting longer. Stargazing is getting more difficult in this Read more…
The European Space Agency (ESA) have officially approved two space missions, LISA and EnVision, for launch in the 2030’s. LISA will search for gravitational waves whilst EnVision will study the interior and atmosphere of Venus. Both missions have contributions from NASA. The process of being formally `adopted’ by ESA can Read more…
Days are getting shorter Nights are getting colder If these shifts you savour You’re a true stargazer I am writing this piece sitting next to a window, having a cup of coffee, and watching it pouring down outside. Not the best day for stargazing, however, it is a good 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…
Those of us out and about on Spring evenings have been treated to a brilliant beacon of light above the western horizon. This is the planet Venus, our closest solar system neighbour. Venus has been called Earth’s “evil twin”, in that it is almost identical in size, mass and density 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…
Welcome to April Stargazers! The month of April brings with it a new financial year, April showers (or snow showers?!) and of course plenty to look out for in our night skies. I’m going to walk you through what to look out for in the night sky over the coming Read more…
A team of astronomers have used the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile to shed new light on planets around a nearby star, L 98-59, that resemble those in the inner Solar System. Amongst the findings are a planet with half the mass of Venus — Read more…
Hello Stargazers and welcome to April! Well, as the saying goes “April showers bring May flowers”, so we may be low on clear nights for stargazing. Due to our climate and location cloud cover often interferes with our ability to see what the night sky has to offer, but we 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…
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…
The answer is possibly, after an international team of astronomers announced the discovery of a rare molecule, phosphine, in the clouds of Venus. Phosphine, which is a molecule made up of one phosphorus atom and three hydrogen atoms, is a gas only made industrially on Earth or by microbes that thrive Read more…
Happy soon-to-be summer, star gazers! June has a few things going for it; it’s the beginning of summer (officially), we have a lovely new moon, there’s some planet spotting to be done in the early morning; and the combined effects of clear, warm days with lower levels of air pollution Read more…
This week it’s Museum Week 2020 and today has the honour of being #ClimateMW day! Here at AOP we monitor the weather daily, and have been keeping weather records for over 200 years – clearly we are very interested in our weather and the climate. On Astronotes we have quite Read more…
Next in our 5 Facts series we have the most evil planet of them all! The second planet from the sun is named after the Roman Goddess of love. However, as we are about to find out, it is far from lovely! Hot, Hot, Hot! Although Mercury is closest to 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…
This is the first Night Sky blog article of the new decade and hopefully I’ll be able to point out some interesting things for you all to see in the night sky this month.
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…
Astrobiology is the study of life on planets or moons other than the Earth. But, to search for life, we must first know what life is. And that might not be as simple a task as you’d think. It turns out that ‘life’ might just be an arbitrary definition that 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…
Satellites, our lives wouldn’t be complete without them. Since the beginning of the Space Race, Satellites have become a major part of how we observe our Solar System and the Universe, and also keep a close eye on our own planet.
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…
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.

Since March means “Mars’ month” in Latin, we should find it a minor coincidence that Earth’s red terrestrial neighbour plays a more major role in the sky over the next few weeks. With continued astronomical twilight, an exploration of the centre ground astrology and astronomy share, and great opportunities to Read more…
You may have heard of the name Galileo. Perhaps it is through an interest in science or maybe it’s from the Queen song “Bohemian Rhapsody”. But who was the man behind the famous name? What did he do and achieve? Well, as Galileo would be 450 years old in 2014, Read more…

We all know how the Sun, our Earth and the rest of the Solar System condensed out of a vast protoplanetary disc some 4.5 billion years ago. There were some early mishaps such as the collisions which birthed the Moon, toppled Uranus and gave Mars its present north-south divide. Also Read more…
