The NASA LCROSS and LRO space mission already confirmed the presence of water frost in the southern pole, but yesterdays’ NASA Read more…
by Galin Borisov and Apostolos Christou This September, we had the first opportunity to make astronomical observations while physically present at the telescope since the start of the COVID19 pandemic. Our instrument of choice was the 2-m RCC telescope at Rozhen Observatory on the Rhodope mountains in SW Bulgaria. So here we are at 1700m above sea level with a forecast for good weather and ready for new discoveries! One 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…

These were – and still are – intensely scrutinised in laboratories all over the world, allowing scientists to gradually piece together the history 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!

Mars is the only other planet in the solar system apart from the Earth that combines a clear – albeit thin – atmosphere and a solid surface. Therefore, an astronaut standing on the surface may observe and record phenomena on the martian sky, both astronomical and atmospheric. One of these 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…
The Perseids meteor shower is one of the most spectacular annual meteor showers. Made of debris from comet Swift-Tuttle they have been observed by sky-watchers for thousands of years and this year the LIC1 camera of the Canary Long-Baseline Observatory (CILBO) at Tenerife captured the peak of the 2020 Perseid Read more…
Are you up for a free ‘firework show’ from Space? If so, this is the month for you because on the 11th August (Tuesday), the Perseids Meteor Shower is coming to town! As our planet silently glides through the cold void of the Solar System (at the phenomenal speed of Read more…
