Hi all,


 

1.  IRISH ASTRONOMICAL ASSOCIATION Public Lecture, February 19, 7.30pm: Dr Ken Smith, QUB: "Sifting the Sky with Pan-STARRS1 - Crunching data from the world's operational digital camera"

Pan-STARRS1 is sending 'astronomical' amounts of data to astronomers, including in particular the team at QUB. It would be easier to list the astrophysical objects about which it is NOT providing information! Dr Ken Smith is involved in this project, and will enlighten us on all aspects of this facinating project.

  The lecture is free and open to all, including free refreshments. Venue: the Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m. 

   Thanks to the Astrophysics Research Centre, QUB, for help in hosting these lectures.

 

2. ISS: The International Space Station continues its current series of evening passes over Ireland on.  It's sometimes the brightest object in the night sky, and you can get details of where and when to look on the excellent and free website www.heavens-above.com.

 

3. METEORITE / SOLAR EVENT AT ULSTER MUSEUM: Dr Mike Simms of the Ulster Museum, Stranmillis Road, Belfast, will present a special event on meteorites on the afternoon of 15th February to celebrate the first anniversary of the Chelyabinsk meteorite fall. If the weather is ok, the IAA will have some telescopes at the front of the Museum for solar observing. We hope to have a telescope display inside instead, if the weather is inclement.

 


4. ALIENS AT ARMAGH PLANETARIUM, 1 March: Planet Aliens is a free live show that tells the story of the Planet Aliens and the wonderful world that they come from.  With a full script and unique music the story will teach children all about the stars and the Cosmos. This is a first of its kind, designed and developed by D-Signs and Displays alongside the team at Armagh Planetarium. With a uniquely designed set, along with props, puppeteers and local actors, this truly is a heart-warming adventure into the Cosmos in search of these wonderful characters. This is a family show which is not to be missed! Suitable for children up to the age of ten. Spaces will be allocated on a “first come first served” basis. Date: Saturday 1 March 2014. Times: 12.15pm, 1.15pm, 2.15pm and 3.15pm. Duration: 30mins. Price: Free

5: CORK: BCO Events:  February's Space Camp is Sold Out! We are now taking bookings for March Junior Space Camp: Sunday March 2 at 12noon. See www.bco.ie

 

6. Advance Notice: Thursday 27 March at 7.30pm Lecture: "Blowing up a storm! Ireland’s record of great winds and the Irish characters who showed the world how to measure them." Dr Kieran R. Hickey, Dept of Geography, NUIG.

Venue: Room OG-029, School of Geography, Archaeology and Palaeoecology, Queen’s University Belfast, Elmwood Avenue, Belfast, BT7 1NN.

Tickets: free, please email to indicate attendance E rgsniat signhotmail.co.uk

   

7. Advance Notice: Trip to Newgrange: Mar 29, 2014: 09.30 – 17.00: I will be leading an astronomy /archaeoastronomy trip to Newgrange, as part of the Stranmillis Adult Learning programme. A day long coach trip, with full commentary. Demand for this is already high, so book now if you are interested. There is a maximum number allowed on the trip, due to space restrictions within the Newgrange Mound. Booking is through Stranmillis College,  http://www.stran.ac.uk/informationabout/courses/professionaldevelopmentlifelonglearning/

The link to the enrolment form is on the same page, but this is the direct link: http://www.stran.ac.uk/media/media,231524,en.pdf

 

8. Advance Notice: COSMOS 2014.  This will be held from 4-6 April, but this year it will be in Athlone, not Annaharvey, Tullamore! So don't be booking any accommodation in Tullamore, as I nearly did! More details when available. See www.tullamoreastronomy.com/pages/cosmos-2014.php

 

9. Advance Notice: Major Astronomy Conference in Galway;  Speed and Sensitivity, Expanding Astronomical Horizons with ELTs. NUI, Galway, 13-16 May 2014

 Led by Prof Andy Shearer: this will be a fascinating look at the future of astronomy as offered by Extremely Large Telescopes, and ever increasingly sensitive detectors. See www.astro.nuigalway.ie/speeadandsensitivity or www.htra.ie/speedandsensitivity


 

10. Advance Notice: STFC Roadshow at QUB, 19 - 25 May. The roadshow, entitled "Seeing the Universe in all its light" features stunning science images and interactive exhibits,   Check the `Seeing the Universe in All its Light’ webpage at:www.stfc.ac.uk/2740 

 

11. Jupiter / Venus Mystery - what mystery? http://www.dailymail.co.uk/sciencetech/article-2556353/Why-Venus-looks-bigger-Jupiter-Galileos-astronomical-puzzle-solved-400-years.html

Eh? Since then was this a mystery? It's because Venus is 5 to 10 times brighter than Jupiter as seen by the unaided eye. Since both objects are too small to be seen as discs by the eye alone (i.e. without magnification) we have no actual visual evidence of their size. The irradiance effect in the eye makes the brighter image look bigger. Also the brain also automatically makes the brighter object look bigger.

   When we use a telescope (with equal magnifications of course) we see the actual size of the planetary discs, so we can see that Jupiter has a larger apparent diameter than Venus (except when Venus is a very thin crescent approaching inferior conjunction, when its apparent diameter exceeds that of Jupiter - and every other planet)

   Similarly, Mars at its brightest is brighter than Jupiter's average brightness, and thus appears bigger, but again Jupiter appears larger in a telescope.

   You might as well ask, 'Why does Sirius appear bigger to the unaided eye than Betelgeuse, even though the latter is actually by far the larger? It's the same effect - 'brighter appears bigger'.

   And you get exactly the same effect when the general public report bright meteors: they say that one was 'bigger' than the other, rather than brighter.

   You would also get exactly the same effect by comparing a bright nearby LED torch with a car headlight a mile away: the former would appear brighter to the unaided eye, though the latter is actually the larger.

   No mystery, really.

If this daft theory was right, then the universe would probably already have been destroyed by other alien scientists observing it a long long time ago!.

   But if they are right, and it will be possible to see 'The End' approaching, it raises one very important philosophical and metaphysical question: 'Will they get enough warning to be able to send out an email to all their colleagues saying "We told you so!", or will it be just a case of having time to say "Oh Shi"
