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
Here we are, on the count down to Christmas, and we’re having a look at all the Astronotes that have been written for our blog this year. We’ve had input not just from the Education Team this year, but also the Academic Staff of the Armagh Observatory and Planetarium.
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.
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.
