Hi all,
1. IAA Lecture, Wed 2 March, 7.30 p.m. by Dr Deirdre Coffey, UCD. Star and planet formation: a whistle-stop tour!
Abstract
Studies of the birth of a star and its solar system have become particularly relevant in this exciting new era of extrasolar planets discoveries. I will outline our current understanding of how a star is born, and how observations of newly forming stars can hint at sites of newly forming planets. Finally, I will outline Ireland's involvement in the European Space Agency's upcoming space mission 'Ariel' to probe exoplanet atmospheres.
Brief Biography
Dr Deirdre Coffey is an Assistant Professor at the UCD School of Physics. She earned her PhD at the Dublin Institute for Advanced Studies (DIAS), which she followed with five years of post-doc experience based at Arcetri Observatory in Florence, Italy, and also at DIAS. She joined UCD in 2012. Her research interests are in the area of star and planet formation. Currently, she is National Program Manager for the European Space Agency's upcoming space mission 'Ariel' to probe exoplanet atmospheres; she is Chair of the Astronomical Society of Ireland; and committee member of the Institute of Physics in Ireland, as well as the Royal Irish Academy's Physical, Chemical and Mathematical Sciences Committee.

5. ARMAGH OBSERVATORY & PLANETARIUM INVITES YOU TO COME EXPLORE
Armagh Observatory and Planetarium is delighted to welcome you this Spring to experience an out of this world trip to remember. The Planetarium is the ideal place to create long lasting memories and spark curiosity to learn more about space.
From immersive dome shows to exploring the cosmos at the interactive exhibition space, and sensory room, there is something to keep everyone captivated during their day out. The planetarium is equipped with a state-of-the-art Digistar 7 digital project system for an all-immersive theatre experience. Visitors of all ages will be immersed in a 360-degree dome experience where shows are played on the roof.
The planetarium is showcasing many dome-shows during spring, suitable for all ages. Shows include, "Astronaut George" best suited for pre-schoolers and little ones. "Perfect Little Planet" is the ideal show for families as you discover the Solar System, taking you on the ultimate space vacation! "We are Stars" is the perfect animated dome show for over 6's and seeks to answer some of the biggest questions for all time; what are we made of and where did it all come from?
The shows are not just for the kids, adults have the chance to view some immersive dome shows too. "Look Up! A Winter Night Sky Tour" takes you on a tour around the night sky as seen from Ireland. Let a presenter guide you through the beautiful objects and constellations seen at this time of year. This show is ideal for anyone starting out in astronomy or interested in learning about what can be seen in the night sky. More shows are available.
The cleverly designed interactive exhibition area allows little ones to explore outer space and broaden their curiosity for the intergalactic phenomena. You can touch a real piece of ancient history; a real meteorite!
To get outdoors, explore the Astropark which has a scale model of the Universe, brought down to Earth in a beautiful natural setting. As you journey through the park you will get to interact with a scale model of the Solar System.
The recently refurbished modern sensory room provides an enjoyable and calming multisensory experience for all our visitors, with features including bubble tubes and interactive exhibits. Leave some time in your day out to refuel at the café and explore the shop for treats, educational gifts and more.
For those with additional needs, a brand-new changing places facility is available to assist to ensure your day out is relaxing and you have everything you need.
Tickets for the dome shows and exhibitions are available to purchase online via www.armagh.space and pre booking is required. The Armagh Observatory & Planetarium is open to the public Tuesday – Sunday.

Webb Space Telescope Community Events and Resources
NASA and its partners want to share the experience of the Webb Space Telescope's first images with communities all over the United States and abroad. The release of Webb's first images in July 2022 represents a unique opportunity to engage our international community. You can apply to be a Community Event host, the deadline for applications is Friday, February 25, 2022. Other resources have been made available to the astronomy outreach community, including a launch kit and many informal education resources.

8. Sun currently furthest from SS Barycentre
Contrary to popular belief, the Earth does not orbit the Sun. Instead, like all the other objects in the Solar System (excepting satellites), it orbits the barycentre, which is the centre of mass of the whole SS. Usually this is located inside the Sun, but occasionally when all the most massive planets line up on more or less the same side of the Sun, the barycentre is displaced noticeably outside the Sun's globe.
That is the situation at present, and the Sun is currently the furthest it will be from the barycente for this century, at a distance of 1.378 mill km, or 1.98 solar radii.

11. UK Students Space Conference, 5&6 March, 2022
NSSC 2022 (ukseds.org) Registration required!
The UKSEDS National Student Space Conference, now in its 34th year, is the premier event for students interested in space, usually uniting them with academics and professionals from across the country to network, share knowledge, and discuss the challenges facing the sector.
Due to the COVID-19 pandemic, NSSC 2021 had to move online, however we managed to preserve the essence of the conference that students know and love. Consequently NSSC 2022 will be a hybrid event, with online attendees being able to watch the talks and ask questions, all through our Nebula platform.
It is open to all, and features talks by leading space science and industry figures, a careers fair, and opportunities to take part in discussions and networking events.
The event is organised by UKSEDS, the UK's national student space society, and is this year hosted by the KCL Space at King's College London.
Follow us on Facebook or Twitter, or subscribe to our email newsletter for updates on this and other events.

18. NEW EASY TEASER: What do Centaurus, Crux and Orion, and only they, have in common?
19. DIFFICULT TEASER – Beat you! No-one got this one, in spite of 6 clues!
Q. What does the number 695 represent?
When you see the answer your initial subjective reaction will be - Wow, that's amazing! Then you'll think – Well, yes, of course!
No correct answers yet, so here's the clues.
Clue 1. The exact figure is 694.83, so it's something we know fairly precisely!
Clue 2: It's to do with the solar system.
Clue 3. It's to do with angular measurement.
Clue 4. Maybe now someone will rise to the occasion.
Clue 5. You don't have to be horizontal to get this one, but…
Clue 6: If I asked you the question 'live', you would probably say, 'in very rough figures - about 720'.
Before I give you the answer, here's the background. You're all probably familiar with the Moon Illusion – the fact that the Full Moon appears much larger when it's rising (or setting) than when it's high up in the sky. I have experienced it many many times, and I know for a fact that it's an illusion (indeed, it's actually very slightly smaller, in those circumstances!). But recently I experienced the illusion so strongly that it was almost unbelievable. As I looked at it, I thought – it looks so big: how many of those would it take to circle the horizon? And, as in clue 6, I thought to myself: 'Well, the Moon is just over half a degree in apparent diameter, and there are 720 half degrees in a circle, so the answer must be about 700'. That figure seemed unbelievable in itself, but I knew that it had to be roughly right. So when I got home, I checked, and the answer is 695. (The Moon's mean apparent diameter is 31' 05.2", so divide that into 360 degrees, and you get 694.83)
