Kilonova lecture, photos sale Insight landing tonight, ISS, Win a zeo-G flight, Exhibition, Xmas Star, Film, Portballintrae, N&M solstice events, Comet Wirtanen, Geminids,

Hi all,
 
1. IAA Public Lecture: " Kilonovae and the birth of multi-messenger astronomy"  28 November, By Prof Stephen Smartt.
   Prof Smartt, who has given us several excellent lectures in the past, is an acknowledged expert in the field of supernovae, and now the new phenomena of kilonovae, which are an order of magnitude more powerful even than supernovae!
SYNOPSIS
  "The talk will describe the remarkable discovery of the first electromagnetic counterpart to a gravitational wave source. The merging neutron star source GW170817 coincided with a short gamma ray burst and several teams located a transient optical source within the region indicated by the LIGO-Virgo Gravitational Wave skymap within 12 hours. A world wide observational campaign on telescopes from x-ray to radio immediately started showing that this electromagnetic transient was unlike any other observed to date. The UV to near-infrared emission showed that high velocity, low mass material was ejected and powered by the radioactive decay of heavy r-process elements. 
The talk will show how the electromagnetic radiation is consistent with models describing what we expect to see when two neutron stars merge."
   Stephen is Professor in the School of Maths and Physics at QUB, and has just recently stepped down as Head of School. He previously worked at the University of Cambridge and at the Isaac Newton Group of Telescopes on La Palma.  He was awarded the George Darwin Lecture of the Royal Astronomical Society in 2018, and previously held two major European awards: an ERC Advanced Grant, and European Young Investigator award. 
   A paper by Stephen in Nature is one of the sources quoted in Wikipedia on the subject –

9. Armagh Planetarium: "Mystery of the Christmas Star" Dome Show Returns, Sat 24 Nov.
Join Armagh Planetarium this Christmas as we journey back more than 2000 years to Bethlehem, and seek to discover an explanation for the star the Wise Men followed to find the baby Jesus in "Mystery of the Christmas Star".  
   The Star of Bethlehem is an iconic astronomical event whose true origin remains unknown even today, in spite of years of speculation and research. The show will guide the viewer through some of these investigations and the most likely causes of this interesting cosmological object which was remarkable enough to make the wise men travel across the desert from Babylon to Bethlehem to see the newborn baby.  You will also explore possible dates for the birth of Christ and look at the historical records of significant astronomical events which occurred at this time.  This modern retelling of the Christmas story in our digital theatre will charm and captivate audiences.
The show opens on Saturday 24th Nov 2018 until Saturday 5th January 2019.
Show Times:
Tuesday – Friday at 2pm
Saturday/School Holidays at 2pm and 4pm
 
10. IAA ASTRO EVENT, Portballintrae, 7 December.
More details next time.
 
11. Comet Wirtanen approaches. This comet, which may become visible to the unaided eye, will be at its best in mid-December, when closest to Earth. It will be at perihelion (closest to the Sun) on 12 December, and soon after that it will pass only 11.6 million km from Earth. That means it will appear quite large, but with a low surface brightness, so a wide-field low power eyepiece or good big binoculars will give the best view. On the night of 15-16 December it will pass just 3┬║ East of the Pleiades. The Moon will then be just past First Quarter, but if you wait until just after midnight it won't intrude.
 You could start looking for it from about 9 December. More details in next bulletin.
 
12. Geminid Meteors peak 13-14 December.
Maximum is predicted for 08h on the night of 13-14 December, so late on the night, especially in the hours leading up to dawn, should give good rates in a clear sky. The ZHR should be around 120, so this is a really good chance to catch quite a few meteors, especially after the 35% crescent moon sets around 10 p.m. The radiant is fairly well up by about 7 p.m., so you can start looking around then. As always for meteors, choose as dark a location as possible, and allow time for your eyes to dark adapt.
 The radiant lies a bit above Castor in Gemini, but the meteors can appear anywhere in the sky. Look about 40-50 degrees away from the radiant, and about 50 degrees above the horizon, in the clearest darkest part of your sky, to see the most Geminids.
   The Zenithal Hourly Rate (ZHR) is the rate which would be seen by an experienced observer, in a VERY dark sky, and with the radiant in the zenith: actual observed rates very rarely reach the nominal ZHR for various reasons.
 
13. APOLLO 8 remembered. This is an excellent video tribute, just coming up to the 50th anniversary in December.   This flight will be the subject of our lecture on December 12.
 
14. IAA New Year Party, 5 January.
The astrosocial event of the year will be held once again at McBrides in Comber, folloqwed by a film and team quiz in the Tudor Private cinema nearby. More details soon.
 
15. Participate in the 100 Hours of Astronomy Global Project, Jan 10 - 13.
In 2019, the International Astronomical Union (IAU) will celebrate its 100th anniversary (IAU100) and to commemorate, we will organise a year-long celebration to increase awareness of a century of astronomical discoveries as well as to support and improve the use of astronomy as a tool for education, development and diplomacy.
   The 100 Hours of Astronomy will be the kick-off worldwide event of IAU100 and will be composed of a broad range of activities aimed at involving the public. 100 Hours of Astronomy will take place over four days and nights, from 10-13 January 2019, with amateur and professional astronomers, astronomy enthusiasts and the general public invited to share their knowledge and enthusiasm for the Universe. Hundreds of local events are being planned by science facilities and astronomy enthusiasts around the world, including telescope observing sessions, exhibitions, lectures, art projects, classroom projects, field trips, special shows and more. In many countries, there will be public lectures by specially selected speakers, experts in astronomy, keen to participate in this planet-wide venture.
   It is only a few months before the yearlong centennial celebration of the International Astronomical Union (IAU) will take place. As a big kick-off event, the global project 100 Hours of Astronomy is organised to take place 10-13 January 2019. Everyone around the globe can participate in this joint effort to bring astronomy to the general public.

   What caused the grooves on Phobos

And if the dead spot was caused by the rolling rocks 'hopping over' a depression, how come there are tracks across the depression of Stickney? And although the gravity is very low, the rocks still had to displace all that surface material to make the grooves, which in some cases go right round the moon – if they had enough initial velocity to do that, they would have left the surface altogether. Finally, why don't we see these rocks at the end of each groove? Doesn't make sense.

Lecture, Observing, Star Tracker at AOP, Nominate John Bell, Win Zero-G flight, ISS, MDSF, Photo Exhib, Astro films, more

Hi all,
 
1. IAA Public Lecture: "Amateur Observations of Meteors."  14 November, By Michael O'Connell).
   Michael, a former chair of the Irish Federation of astronomy Societies, is an experienced amateur observer and photographer in several fields, including solar and meteor studies.
   This talk outlines where meteors are from, why we have meteor showers and how to observe them.
Michael describes the meteor science that amateur astronomers can play an active role in.  
In particular, the talk outlines how to detect meteors using visual techniques, with cameras and via radio.
The talk also outlines why it's useful to observe meteors as part of a group effort.
