Lecture Weds 15th Feb - Dr Michele Bannister, QUB "Icy Wonders of the Outer Solar System"

Dr Michele Bannister
Recent discoveries are revealing intricate structure in the populations of tiny icy worlds that orbit far beyond Neptune. Surveys with some of the world’s largest telescopes are mapping the depths of this vast region. With the >800 discoveries from the Outer Solar System Origins Survey, we are writing the history of how our Solar System was sculpted into shape by the migration of Neptune and the other giant planets. I’ll also discuss the few known extreme orbits in this region, and whether they hint at the elusive presence of a distant giant Planet Nine.

ISS Lunar Transit Photographed from Sprucefield

IAA President Paul Evans has successfully imaged a transit of the International Space Station (ISS) from Northern Ireland. Using information provided by the website Calsky.org, Paul determined that Sprucefield near Lisburn would be on the centreline of the transit which would take place after the ISS had passed Venus and Mars and moved into Earth's shadow. It so happened that the sky was clear if slightly hazy so an attempt was made. Paul used his Celestron ED 80 telescope with Lumix G7 camera at prime focus in 4K video mode, taking 25 8 megapixel images every second.

Lecture Weds 1st Feb: 'All Craters Great and Small' , by Dr Mike Simms, Ulster Museum

Dr Mike Simms
Fewer then 200 impact craters are currently known on Earth but others must lie hidden beneath younger rocks. At Meteor Crater, in Arizona, the classic example of an impact crater, Mike will explain how careful detective work over many decades led to the realisation, firstly, that all is not what it seems, and ultimately gave rise to an understanding of some of the Meteor Crater enigmas.

Lecture 18th January - Dr Kate Maguire, QUB, "Cosmic Lighthouses: Supernovae and the Dark Universe"

Dr Kate Maguire
Supernovae mark the explosive deaths of some stars at the end of their lives. These incredibly bright explosions can be seen to great distances in the Universe. Supernovae were essential to the unexpected discovery that the expansion rate of the Universe is accelerating, invoking the presence of the mysterious and unexplained quantity, dark energy. I will describe what we know (and don’t know) about these stellar explosions, and how future transient surveys plan to use them to uncover the nature of dark energy.

Lecture 4th January 2017 - Prof Mike Burton, Director, Armagh Observatory & Planetarium - “Galactic Explorers - Mapping the Molecular Gas of the Southern Milky Way”

Prof Burton at the Clotworthy Launch Picture: Bernie Brown

Professor Mike Burton has recently taken on the Directorship of Armagh Observatory and the Planetarium bringing both bodies under a single management. Prior to this he spent many years in Australia carrying our research into how stars form and the excitation of the interstellar medium in which this occurs. This makes uses the tools of infrared and millimetre-wave astronomy, measuring the spectral signatures arising from the gas and dust in interstellar molecular clouds.

We are very pleased to welcome Prof Burton to the IAA to talk to us about "Explorers of the Galaxy"
