Hi all,
ƒŠ
1.ƒŠƒŠIRISH ASTRONOMICAL ASSOCIATION Public Lecture, February 19, 7.30pm: Dr Ken Smith, QUB:ƒŠ"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.
ƒŠƒŠThe lectureƒŠis free and open to all, including free refreshments.ƒŠVenue: the Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m.ƒŠ
ƒŠƒŠ Thanks to the Astrophysics Research Centre, QUB, for help in hosting these lectures.
ƒŠ
2. ISS: The International Space StationƒŠcontinues its currentƒŠseries of evening passes over Ireland on.ƒŠ It's sometimes the brightest object in the night sky, and you can get details of where and whenƒŠto look on the excellent and free website www.heavens-above.com.
ƒŠ
3. METEORITE / SOLARƒŠEVENT 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 meteoriteƒŠfall.ƒŠIf the weather is ok, the IAA will have some telescopes at the front of the Museum for solar observing.ƒŠWe hope to have a telescope displayƒŠinside instead,ƒŠif the weather is inclement.

4. ALIENS AT ARMAGH PLANETARIUM, 1 March: Planet Aliens is a freeƒŠlive show that tells the story of the Planet Aliens and the wonderful world that they come from.ƒŠ With a full script and unique music the story will teach children all about the stars and the Cosmos.ƒŠThis 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.ƒŠSpaces will be allocated on a âÀÜfirst come first servedâÀÝ basis. Date: Saturday 1 March 2014. Times: 12.15pm, 1.15pm, 2.15pm and 3.15pm. Duration: 30mins. Price: Free

7. Advance Notice: Trip to Newgrange: Mar 29, 2014: 09.30 âÀÓ 17.00: I will be leading an astronomy /archaeoastronomy tripƒŠto Newgrange, as part of the StranmillisƒŠAdult Learning programme. A day long coach trip, with full commentary.ƒŠDemand 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,ƒŠ http://www.stran.ac.uk/informationabout/courses/professionaldevelopmentlifelonglearning/

11. Jupiter / VenusƒŠMystery - 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.ƒŠThe irradiance effect in the eye makes the brighter image look bigger. Also the brain alsoƒŠautomatically makes the brighter object look bigger.
ƒŠƒŠ 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)
ƒŠƒŠ Similarly, Mars at its brightest is brighter than Jupiter's average brightness, and thus appears bigger, but again Jupiter appears larger in a telescope.
ƒŠƒŠ You might as well ask, 'Why does Sirius appear bigger to the unaided eye than Betelgeuse, even though the latter is actuallyƒŠby far the larger? It's the same effect - 'brighter appears bigger'.
ƒŠƒŠ 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.
ƒŠƒŠ You would also get exactly the same effect by comparing a bright nearbyƒŠLED torch with a car headlight a mile away: the former would appear brighter to the unaided eye, though the latter is actually the larger.
ƒŠƒŠ No mystery, really.

More anthropomorphising! - "Unruly" stars "gather material hungrily from the space around them. A young star will continue to feed its huge appetite". What next - 'bad table manners'? 'Indigestion'? What about 'adding sauce, and salt and pepper'? Where will this end, as one writer tries to out-do another in dumbing down scienceƒŠarticles?

If this daft theory was right, then the universe would probablyƒŠalready have been destroyed by other alien scientists observing it a long long time ago!.
ƒŠƒŠ 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 justƒŠa case of having time to say "Oh Shi"
