Peter’s private post

It’s time the UN set up a licensing authority to permit space colonization and mining, with extremely stringent rules which would effectively rule out either. Many parallels with a History of Britain – The Humans Arrive  tap for video. And here’s a nice sunset to prove it. Pity I can’t remember how to add a caption to the photo. I got it via the little drop down triangle and selected Inline image, though that’s not how I did it before, if I recall aright. Late edit.

I’ve made this private and sticky via the quick edit screen though I don’t really understand either. Well I thought I made it private but it just shows up on the list as draft. Have worked out how to insert a para after the photo, bravo!

Must remember to ask Garry about tags. Looking forward to learning about excerpts. Also can we tidy up the list of posts, put them in folders perhaps?

Here you can find out about the monthly observers group meetings, how to get on the alert list for weather-dependent observing sessions, and how to get advice on buying a telescope. Find out about the workshop programme and make your own suggestions for topics you would like included. Discover our field trips, the annual outing, and social events, and let us know what you hope to get from your Club membership. We are always open to consider new activities.

“The mysteries of Black Holes, large and small” – Mon 10 Feb 2020, 8pm

For our February lecture, UCC Professor of Physics and Astronomy Dr Paul Callanan will talk about those mysterious objects so fundamental to astronomy, black holes.    The date is Mon 10th Feb 2020 at 8 pm, and the venue is UCC.   Please arrive 10 minutes early, or if you wish to join, then ideally at 7.40 if you can.

Understanding the nature of black holes remains one of the great challenges of modern astronomy.

More than 100 years ago, Einstein produced a remarkable theory which could be used predict the basic properties of black holes, but it was only this year, in 2019,  when we finally got a glimpse of what a black hole really looks like. In this talk Paul will explore what we know about black holes, and what the most recent observations tell us about them. We will also see how Irish astronomers, 100 years ago this year, made observations which helped to show that Einstein’s theory of gravity was correct; an important milestone in the application of his theory to black holes and the universe at large.

“Back to the Future: Celestial Navigation for Ocean Positioning” – Mon 13 Jan 2020

At our January lecture, Master Mariner and nautical science lecturer Bill Kavanagh demonstrated his sextant. We learnt how traditional methods were used to obtain a ship’s position by observing astronomical objects, and how such methods are being used again today in an era of global navigation satellite systems.  GPS and other satellite navigation systems (including the not yet operational European Galileo system) are accurate, but subject to human error and malfunction. For 20 years the US navy and coastguard abandoned celestial navigation training for officers, but have now reinstated it – recognizing that the Sun and stars will never be disabled by solar flares, and can’t be shot down.

Bill is a committee member of Cork Astronomy Club and also lectures in the National Maritime College of Ireland at Ringaskiddy. After a 20-year career at sea including 8 years in command, he moved ashore to start a new career in education and training. He currently lectures and co-ordinates the award year of the BSc honours degree in nautical science, and is an adjunct lecturer in research methods with Jade University of Applied Sciences, Oldenberg, Germany. While at sea, he navigated the Atlantic, Pacific and Indian Oceans using celestial navigation techniques.

“Space Law: Weapons, Property Rights and Mining in Space” – 14 Oct 2019

Barrister Laura Keogh, a specialist in space law, gave an overview of space law and then focused on weaponisation and the legality of owning asteroids.    

LauraShe began by outlining the framework of international space law, starting with the 1967 Outer Space Treaty, which forms the basic framework, and then identified three challenges for space law – militarisation, space mining, and colonising Mars.   Space has been militarised since the very start of the space age, but what weapons are allowed? Nukes are definitely banned and so are weapons of mass destruction – but what are those?  A US act of 2015 says citizens can own asteroid resources, but is this legal in international law? 

If Mars is colonised, will it be a state and what are the implications of that?  The meeting broke into groups to discuss how a Mars state would cope with a refugee problem from Earth, giving rise to some daunting proposals.

Laura has campaigned, thus far without success, that Ireland should be represented at the United Nations Office for Outer Space Affairs (UNOOSA).  This will become more urgent with the launch next year of Ireland’s first satellite, Eirsat1. She works for MHL- Law dealing with space sector clients and data protection issues.

“The Active Sun: Solar Eruptions and their Impact on Earth” – Mon 11 Nov 2019

On Monday 11th November we welcome Trinity College space weather scientist Dr Sophie Murray, who will look at solar flares, coronal mass ejections, and auroras. All this is called space weather, and she will discuss its impact on the Earth’s upper atmosphere, and potentially on human civilisation.  All lectures are on Mondays at 8pm, and the venue is UCC.   Please arrive 10 minutes early, or if you wish to join, then ideally at 7.30 if you can.

Dr Murray’s interests include developing operational solar eruption forecast products in weather prediction.   She will no doubt refer to the 1859 Carrington Event, which gave us the first alert that solar flares can interfere with our electronics.

This lecture was originally slated for 14th Oct 2019.

Nov 9 Introduction to Astronomy. Tom Bonner will present this introductory workshop designed for new members (or, maybe not so new members!) An overview of the past to the future, highlighting what astronomy has meant to humankind and where it could be talking us. We will travel to the extremes of both time and space.   10. 30 Tory Top Road Library. – Go to Calendar for further details

Nov 30 The Ecliptic. The Ecliptic Plane is the projection of Earth’s orbit onto the celestial sphere. … Besides defining the path of the sun, the ecliptic marks the line along which eclipses occur, the moon and planets and asteroids wander, the Zodiac constellations live. Confused? Tony Jackson will explain all. As usual it will be held in Tory Top Road Library at 10.30 – Go to Calendar

Celebrate Apollo day 20th July 2019 at Tory Top Library

We celebrate the 50th anniversary of the Moon landing
On Saturday 20th July, Cork Astronomy Club celebrated the 50th anniversary of the Moon landing at Tory Top Library, Ballyphehane.  Members and the public attended, memorabilia were on display and Tony Jackson who remembered the event, gave a highly praised talk and showed a video. Authentic 1969-recorded footage of Apollo  11’s mission as well as memorabilia from the time, such as a model of the Saturn V rocket, and much more.  

The Pope’s Astronomer at Blackrock Castle on 10 Aug 2019

Club members met Papal Astronomer Bro Guy Consolmagno, author of Turn Left at Orion, at Blackrock Castle Observatory on Saturday 10 August, from 11:30 am to 12:30 pm.  Bro Guy will gave a talk “Discarded Worlds: Astronomical ideas that were almost correct …”. You can read his abstract below. As well as astronomers who were wrong he cited those who were right but for the wrong reasons – Galileo being a prime example.

The event was fully subscribed.   Bro Guy is an incisive and entertaining speaker,  and the author of numerous books on astronomy including  Turn Left at Orion – Hundreds of Night Sky Objects to See in a Home Telescope – and How to Find Them

You can find more about Bro Guy at his page on the Vatican Observatory website. He provided the following abstract for his lecture:

Astronomy is more than just observing; it’s making sense of those observations. A good theorist needs to blend a knowledge of what’s been observed, with a good imagination … and no fear of being wrong. Ptolemy in ancient Rome, the medieval bishops Oresme and Cusa, the 19th century astronomers Schiaparelli and Pickering, all rose to the challenge; and they were all almost correct. Which is to say, they were wrong … sometimes hilariously, sometimes heartbreakingly so. What lessons can 21st century astronomers take from these discarded images of the universe?
