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…
World renowned astronomical research centre, Armagh Observatory and Planetarium, has co-authored a research paper that announces the discovery of eight new and very hot stars with effective temperatures exceeding 100,000K. Published by the Royal Astronomical Society, the paper* is based on data gathered using the Southern African Large Telescope Read more…
So, party season is over and we’re looking towards a long, cold January before the weather starts to heat up again. However, January is a great time to go stargazing as the nights are long and we can start our lookout in the late afternoon. Not to mention that the Read more…
The story of Jocelyn Bell Burnell’s discovery of pulsars is one of the best known in astronomy. The story of how, as a graduate student at the University of Cambridge, she detected “a bit of scruff” on the chart recorder of the radio telescope designed by her supervisor Anthony Hewish. Read more…
At least one out of four white dwarfs will end its life as a magnetic star! At the end of their life, most of the stars shrink in size to the dimension of a small planet, a stage of the stellar evolution which is called “white dwarf”. In a new Read more…
In a new paper, Simon Jeffery reports the discovery of standing waves on two small hot stars similar to the pattern of jet streams seen in the Earth’s atmosphere.
How astronomy can help us understand the spread of a pandemic Article by Michael Burton, Director of the Armagh Observatory and Planetarium The Hill of Infinity of Armagh, in the Astropark of the Observatory and Planetarium, contains a scale model of the universe, illustrating the place of planet Earth in Read more…
By Simon Jeffery, AOP Research Astronomer In 1930, Dorrit Hoffleit reported that star number #4749 in the Harvard List of variables had faded four times between 1897 and 1929, and identified it as an R Coronae Borealis (RCB) variable. RCB stars are luminous low-mass stars (red giants) with surfaces around Read more…
By Christopher Duffy Studies of the sun, our closest star, have shown that sun spot activity and solar eruptions, also known as solar flares, are strongly correlated – regions of the sun with many sun spots are found to be the typical point of origin for most solar flares. This Read more…
Moving on to our February Night Sky article (already) featuring htings to look out for while the sun still sets nice and early. Watch out for the cold, though!
