Lecture, close miss, Science events, Comets latest, SAN, Observing, NISF, GSP...

Hi all,
 
1: IAA LECTURE: Next IAA public lecture: Feb 04, 7.30 p.m. by Tom O'Donoghue
"Astrophotography: From Single Pane to Mega-mosaic". This will look at medium focal length Deep Sky Astrophotography.
   Tom O'Donoghue, from Dublin, takes some of the best deep sky astrophotos you will ever see taken by any amateur astronomer. Visitors to any of the recent Irish Star Parties will have seen the amazing quality of his images. He is totally dedicated, indeed obsessed, to get the best quality images possible! Frustrated by the sky conditions in Ireland, he started travelling first to Southern France, and then Spain, to get the best possible conditions.
   As well as taking the superb shots you can see on his website www.astrophotography.ie he is now working on a 'mega-mosaic' of the whole Orion constellation and all its associated nebulosity, of which the best known are of course the Orion Nebula itself (M42), the 'Running Man Nebula', and the Horsehead Nebula. But there's much more!
   In this talk he will describe how he acquired his skills and his equipment, how he takes and processes the images, and describe his Orion Mega-Mosaic."
   Tom will have some of his smaller size, but same high quality, prints available for sale at £15 each.
    The lecture is free and open to all, including free refreshments. Venue: 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.
N.B: Our last lecture on Wednesday 21 January, by well-known QUB astronomer, Professor Alan Fitzsimmons, "Rosetta at comet 67P/Churyumov-Gerasimenko", was probably our best-attended 'normal' lecture ever, with about 130 people present: almost every seat was taken!. All thoroughly enjoyed an amazing and very entertaining presentation - thanks Alan.
    
2. "Close" Asteroid Flyby on Jan 26. 
http://www.huffingtonpost.co.uk/2015/01/26/asteroid-2004-bl86-flypas_n_6545028.html?ir=UK+Tech  There are two errors in this report:
1. The reference to 1 million asteroids 'in our galaxy' should of course be to 'in our Solar System'.
2. Quote: "Unfortunately the tracking of very large asteroids can only make a practical difference if we're then able to do something about the rock - deflecting or destroying it, preferably. And unfortunately - again - NASA's best guess on how to do that so far is… prayer."
   That is wrong on four counts: firstly that is not actually what NASA said; secondly there are several ways to deflect or reduce the threat from an incoming asteroid, provided that we get at least a few years warning; thirdly there is zero evidence that prayer changes the orbits of asteroids, or anything else. It doesn't prevent volcanic eruptions, earthquakes, tsunamis, floods, mudslides, avalanches, hurricanes, tornadoes etc, so why would it deflect an asteroid? Quite apart from the fact that that would require altering the laws of physics.
   Fourthly, we do already track ALL "very large asteroids". It's the ones between 0.5 and 1km where we have only tracked about 99% of the dangerous ones so far, and the ones between about 100m and 500m where we may have only got about 90% of the dangerous ones so far, that the problem lies. And we COULD do something about them if we detect them in time. But they are NOT "very large asteroids": "Very large" for an asteroid would mean 10km diameter or more, and we are tracking 99.999% of them, and none will hit us within the next few hundred years, nor probably even in the next millennium or longer. And the chance that the one in 100,000 which we may have missed so far would hit us within the next millennium are infinitesimally small
   Very sloppy journalism.
For a video taken from UK see http://youtu.be/_96nt1h5X90
And of course the usual UFO nutters are in on the act! http://www.ufosightingsdaily.com/2015/01/ufo-orbits-asteroid-2004-bl86-jan-2015.html and http://www.huffingtonpost.co.uk/2015/01/28/doomsday-asteroid-ufo-not-moon_n_6560982.html. The folks at UFO sightings daily seem to have a neuron count equivalent to that of a jellyfish. And that's all of them - collectively.
   Why would an alien spaceship need to hitch a ride with a small boring slow-moving asteroid? That would be like a Bugatti Veyron tucking in behind a school bus to get a bit of reduced air resistance!

5. Comet Lovejoy: Terry Lovejoy's 5th comet, official name C/2014 Q2, is now high up in the Northern sky and after reaching naked-eye visibility, will soon start to fade as it moves away from both Earth and Sun. Currently it shines at between 4th and 5th magnitude, just visible to unaided eyes in a dark sky, but relatively easy in binoculars. It's currently passing through Andromeda. IAA members have got some lovely photos of it - see the website: www.irishastro.org. 
 Positions and finder charts for the comet on a daily basis are on the excellent free site www.heavens-above.com 
 
6. Comet 67P - Latest from Rosetta:
http://www.dailymail.co.uk/sciencetech/article-2926590/Comet-67P-ve-never-seen-Rosetta-reveals-colourful-views-gravity-temperature-organic-compounds.html  I made the point about light bouncing off the two lobes on either side of the neck, and thus increasing the radiation there, at Alan's recent lecture! 
 
7. SKY AT NIGHT BROADCAST:  Sunday 8th February at 22:00 on BBC4. They will be asking: What Have UFOs Done for Us? http://www.bbc.co.uk/programmes/b052hpyd (A: sold lots of books, DVDs,  cinema tickets, generated lots of websites, and lately, via the Web, proved just how gullible lots of people are!)
 

8.  IAA Observing Nights at Delamont Country Park

These very popular weekend observing sessions have recommenced, with the nights of Feb 13 & 14 as next option. Delamont is well signposted off the A22 just South of Killyleagh, (North of Downpatrick) Co Down. They are suitable for anyone, but are aimed especially at beginners. We bring our own large telescopes; bring your own if you have a portable one. The events work like this: If it's clear on the Friday night, the event goes ahead. If not, we try again on the Saturday night. If both are cloudy, we try again on the following weekend, same procedure. To check if it's going ahead, check the IAA website: www.irishastro.org up to 6.0 p.m. on each day, and for dates for next session: If cloudy, we'll try again on the next date on the list.…

http://www.dailymail.co.uk/sciencetech/article-2927558/The-half-mile-wide-space-disk-lead-space-telescope-1-000-times-sharper-Hubble.html But as it's to be in a geostationary orbit, it needs to be over the equator, not over the southern tip of South Africa, which is about 34 degrees South - so the illustration is wrong. Even if it is by NASA!
And it won't be easy to point or control! And the mountain-top test will be seriously hampered by looking through a large air mass and bad seeing, as the star will necessarily be quite close to the horizon.
http://www.dailymail.co.uk/sciencetech/article-2928456/Sun-like-star-dating-dawn-Galaxy-shed-new-light-planets-form.html The pioneering technique of asteroseismology was beautifully described by Prof Don Kurtz in his recent lecture to the IAA
  http://www.dailymail.co.uk/sciencetech/article-2923635/NASA-spacecraft-Pluto-Smile-camera.html  NB, Pluto may not be the largest body in the (Edgeworth-) Kuiper Belt - there is still some doubt as to whether Pluto or Eris is the larger.
  http://www.dailymail.co.uk/sciencetech/article-2929876/Lightning-doesn-t-strike-twice-unless-SPACE-Stunning-video-reveals-multiple-strikes-ISS-orbits-Earth.html  Great images of the airglow, especially the one by Samantha Christoforetti. The airglow is what finally determines the faintest limiting magnitude of stars visible from the surface of the Earth - even from the darkest possible site, with no moonlight etc. The lights from the stars themselves, particularly if the brightest part of the Milky Way is overhead, also contributes. But even if the MW is low down, circling the horizon, and there are no bright planets up, there's still that background airglow.
  http://www.dailymail.co.uk/sciencetech/article-2929743/The-world-s-powerful-rocket-SpaceX-animation-shows-Falcon-Heavy-lift-one-day-send-humans-Mars.html  It would be far more efficient to bring the rocket down most of the way slowly under a parachute before using the rocket engine to slow it down enough for a soft landing at the very end. That would mean they would need much less fuel for the descent operation, which in turn means that they would need much less fuel to get that extra fuel up to the cut-off stage in the first place!
No global firestorm from K-T Impact? http://www.sciencedaily.com/releases/2015/01/150122084849.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Ftop_news%2Ftop_science+%28ScienceDaily%3A+Top+Science+News%29 But there would also have been giant hot lumps of rock blasted high into the atmosphere, and falling back over a wide area, which would have caused fires in a large radius around the impact site.
Black holes exist in certain gravitational theories http://www.sciencedaily.com/releases/2015/01/150123102219.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fspace_time+%28Space+%26+Time+News+--+ScienceDaily%29 I can't even start to understand this, but it may be of interest to some!
The Two Faces of Mars http://www.sciencedaily.com/releases/2015/01/150128125414.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Ftop_news%2Ftop_science+%28ScienceDaily%3A+Top+Science+News%29 Just one question - where did a body of diameter 3200km, made MAINLY OF IRON come from? And since the mean density of Mars is only 3.93 (compared with 5.52 for the Earth), it has relatively little iron even now. Before that impact it must have had even less. So how come there was a substantial 'mainly iron' body circulating around, but very little iron available to the proto-Mars? Formation in different regions of the proto-planetary disc is one explanation, but even so it seems an odd dichotomy.
http://www.sciencedaily.com/releases/2015/01/150128082241.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fspace_time+%28Space+%26+Time+News+--+ScienceDaily%29  If that's 'God's hand', he obviously needs a good orthopaedic surgeon! Why is there this need to 'Deomorphise' (my new word for this, analogous to anthropomorphise) objects seen in the sky? First we had the 'Eye of God', and now this. What next - his mouth? his nose? his ear? his big toe?

21. UFOlogists Laughs section:
http://www.huffingtonpost.co.uk/2015/01/28/unexplained-floating-ball-of-fire-ufo_n_6561314.html?ir=UK+Tech 
UFO? -  It's just the Sun shining on & through a small lenticular cloud.
And http://www.dailymail.co.uk/sciencetech/article-2928641/UFO-hunters-plan-massive-database-track-alien-sightings-say-teach-mankind-travel-distant-galaxies.html So when, with almost everybody having a phone with a camera, and with 'on the spot' real life photos and videos from the public of everything from fireballs to plane crashes, are we going to get a CLEAR, genuine, incontrovertible image of an alien spacecraft? I'll bet not even in the next 10 years. And I'll back that up with £1,000, if anyone wants to accept the wager. Why? Because none of the 'sightings', or photos, so far has been a genuine alien spacecraft, and I doubt if any are suddenly going to visit us within the next 10 years.
Wow! That is SOOO convincing! But the commentary has got one thing wring - s/he's not wearing a helmet, as you can see the irregular outline of his/her wavy hair. So obviously s/he is either a Martian, or else a human who has been there so long that they have adapted to living in the almost non-existent Martian atmosphere. Isn't that AMAZING????

Lecture, close miss, ISS, Fireball, Science event, Comet, IFAS, Star parties

Hi all,
 
1: IAA LECTURE: Next IAA public lecture: Tonight - Wednesday 21 January, QUB, at 7.30 p.m. It will be given by well-known QUB astronomer, Professor Alan Fitzsimmons. Title: Rosetta at comet 67P/Churyumov-Gerasimenko  Synopsis: "This year the European spacecraft Rosetta became the first spacecraft to rendezvous with a comet, and the first to place a lander on its surface. The 3-day landing and operations period of the Philae lander was followed by millions of people around the world. Yet we still have at least a year of stunning science to come from Rosetta - plus hopefully some more from Philae. This talk will summarise the aims of the mission, show some of the first results, and explain some of what will happen in the coming months."
   Everyone is aware of the amazing pictures coming back from the Rosetta probe at Comet Churyumov-Gerasimenko. But there's an awful lot more than just the pictures, as our local comet expert, Alan Fitzsimmons, will reveal. I think it's fair to say that this mission has completely revolutionised our ideas about comets, and it's bound to be a fascinating and informative talk, by an acknowledged authority on the subject.
NOT TO BE MISSED!
   The lecture is free and open to all, including free refreshments. Venue: 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. "Close" Asteroid Flyby on Jan 26. Not that close, but quite a hefty chunk of rock! See http://www.dailymail.co.uk/sciencetech/article-2910631/Look-Nasa-warns-January-26th-asteroid-Earth-s-closest-call-2027.html  Another misleading illustration of an approaching asteroid
It will be visible in good binoculars or a telescope when it gets far enough North to get well above our horizon.
See this for more details and a chart http://www.universetoday.com/118187/big-asteroid-2004-bl86-buzzes-earth-on-january-26-how-to-see-it-in-your-telescope/. That chart may not be exactly right for our location in Ireland, but it will be close enough to find and track it, Note that it passes through the Beehive Cluster, or Praesepe, in Cancer!
 
3. ISS The ISS continues its current series of morning passes over Ireland until 25-26 Jan.

16. The "Moon in 2015" is a complete annual guide to our natural satellite. A table gives you the dates for each of the Moon's phases: New, First Quarter, Full and Last Quarter. The Moon swings through these phases every 29 and 1/2 days, but did you realise the exact length of this period changes from month to month? On what dates are the "Super Moon's" for 2015? And what about the dates of Perigee and Apogee, Ascending/Descending Nodes, and Lunar Standstills? You'll find all of this as well as a recap of solar and lunar eclipse for 2015 in Jay's blog. http://www.astropixels.com/blog/2014/12/moon-in-2015/

 

17. ARCHAEOASTRONOMY TRIP TO NEWGRANGE and KNOWTH, 2015, These trips have proved so popular that as soon as I got back from the last one, Stranmillis University College Institute of LifeLong Learning asked me to lead another one next spring!  Like the last one, the next trip will include a visit to the Knowth Tomb as well. It has the largest collection of Megalithic art anywhere in Europe in one single site, some of which is reckoned to be astronomical. Booking for thus very popular, non-technical trip will open later, but if you want to go, note the date in your diary: Sat 9 May. More details when the new brochure comes out.
