Written by Chris Duffy, PhD Candidate AOP William Herschel, who died 200 years ago this year, is famous for a number of things we take for granted in modern astronomy, not least his discovery of Uranus in 1781 the first planet discovered in the modern era of astronomy. Less known Read more…
Armagh Observatory and Planetarium reports that, if skies are clear on the morning of 10th June 2021, sky-watchers will witness a partial eclipse of the Sun. A solar eclipse occurs when the Moon passes between the Earth and the Sun, in effect casting a shadow on our planet. When the Read more…
What do a tree, a colander and a piece of cardboard have in common? The answer: they can all be used to observe a solar eclipse! Our Sun – the brightest star in the sky – has been the subject of intense scrutiny ever since human beings began to interrogate Read more…
The transition region in the Sun is the atmospheric layer that separates the cooler chromosphere from the hotter corona. Studying the structure and dynamics of the transition region requires greater attention as these provide critical information on the supply of mass and energy from the lower atmosphere to the corona and Read more…
By Professor Gerry Doyle The solar chromosphere is a complex magneto-plasma system that offers the evolution of a variety of plasma dynamics (e.g., jets, mass motions, shocks) as well as magnetic waves. It is separated by the inner corona through the particular discontinuities of mass, density, temperature, characteristic speeds, etc. Read more…
Just released are first images and videos from the National Science Foundation’s (NSF) Daniel K. Inouye Solar Telescope (DKIST) – revealing unprecedented detail of the Sun’s surface, with experts saying it will enable a new era of solar science and a leap forward in understanding the Sun and its impacts Read more…
AOP researchers have used data from a NASA space mission to shed light on one of the most violent phenomena in our solar system – magnetic explosions on the surface of the Sun. Abhishek Srivastava, formerly a research associate at AOP and now a solar scientist at the Indian Institute Read more…
Observers in Ireland and Great Britain will have an opportunity, weather permitting, to observe a rare astronomical event on Monday 11th November, when the planet Mercury will transit across the Sun. Transits occur when a planet lies directly between the Earth and the Sun. With suitable observing equipment, Mercury may Read more…
The Sun’s corona is maintained at a temperature in excess of a million degrees. The corona lies above the solar photosphere which is maintained at 6000 degrees. These regions are only a few hundred kilometers apart. A major scientific problem in solar physics is how and why is the corona Read more…
To follow on from last week’s post on grid computing in our series on the technological applications of astronomy to society we have an article on spectroscopy and the discovery of a new element in the cosmos – helium – by Armagh Observatory and Planetarium’s Michael Burton. He is our Read more…
