AAS

Our inaugural meeting was on the 8th November 2010 and we officially formed in February 2011.
AAS holds monthly meetings with guest speakers.

All guests are welcome!
No knowledge necessary, just a curious mind.

We are able to provide assistance with setting up your telescope or just helping to find your way around the night sky.

AAS is able to host discussions on subjects as varied as Dark Energy through to 'How dark is your sky'.

Come along and get a new perspective on the universe in which you live!

Monday 8th Oct, Next Meeting

The next meeting will be on Monday, 8th Oct.  Usual time and place:- 7:30pm at the Kings Head, next to Abergavenny town hall.

This month rather than mainly talk about a single item there are a number of topics that have caught my eye over the last few weeks that we can explore.  I have put a brief list below.  Depending on how the discussions and exchange of views/ideas goes we may or may not cover all the topics.

  • Is there no one out there??  Exo-planets and panspermia in the news, again. 
    At present there are 3,851 confirmed planets in 2,871 systems.  Now a possible exo-moon has been discovered.  Plus a new approach to boost the chance of finding extraterrestrials (if any!) and also researchers have generated phosphates, a key part of DNA, in conditions like the molecular clouds that form solar systems.
  • Gaia – A 5 year mission to construct the largest, most precise three-dimensional map of our Galaxy by surveying more than a billion stars.
    The 2nd data release, last April, provides info on the position, parallax and proper motion of 1.3 billion stars. New insights have started to come from this data.
  • Have we found the last of the missing ordinary matter in the universe?
    Previous observations have failed to find half of the normal matter in the universe. Now this matter has been found, in diffuse gaseous filaments between the galaxies. As this gas is cold and diffuse it has been impossible to see it but new techniques have confirmed its existence.
  • Inflation: Yes or No? How did the universe start.
    A short video about inflation (only 2 mins) from David Kaplan. Plus Roger Penrose’s theory that the universe is cyclical.
  • Very Big and Very Early.
    Another massive black hole discovered that is 780 million times the mass of the sun and dates from 670 M years after the big bang.  How did it get so big so soon?
  • Solar System.
    Still arguing about Pluto’ status; a new body some 80AU from the sun (Pluto is 34AU) which hints at Planet X further out; more evidence for a turbulent period involving the gas giants during the evolution of the solar system; how Curiosity’s motor confirmed the Mars dust storm had gone global.
  • Dark Matter.
    A new analysis has ruled out primordial black holes, formed at the birth of the universe, as being the mysterious dark matter. Plus a new wide field map of the 3 dimensional distribution of matter in the universe, based on looking at 10 million galaxies, “gives us a better picture of how much dark energy there is”.

If there are any topics or ideas that anyone wishes to talk about do bring them along or let me know by email or at a meeting.  All input is most welcome.

All comers welcome.  No expertise required, only a inquisitive mind.  See you on Monday.
