Moray's Astronomy Club, SIGMA

Forthcoming Meetings

1st September 2017
Hunting the Dragon
Prof. Andy Lawrence, Royal Observatory Edinburgh
Mysterious and violent events take place in the very centres of galaxies - huge outpourings of X-ray and ultraviolet radiation, jets streaking out at nearly the speed of light, and erratic changes from week to week.  Andy will trace the history of how we have pieced together the puzzle over several decades, with telescopes, detectors, and theory, and look at what we think we understand now.

6th October 2017
Transiting Extra-Solar Planets: From Hot Jupiters to Super-Earths
Prof. Andrew Cameron, University of St Andrews
Extrasolar planets that transit their host stars are highly prized, because we can measure their radii as well as their masses.

Prof. Cameron will describe some of the problems faced in extracting planetary parameters from the various types of astronomical observation needed to deduce planetary bulk densities, which offer clues as to whether planets are mainly rocky, icy or gaseous.

A bewildering variety of planetary compositions is beginning to emerge, many of which are not represented in our own solar system. In particular, analyses of the planet population found by the Kepler/K2 space mission suggest that we may soon have an idea of the prevalence of Earth-sized planets around other stars.

The full programme for 2017 can be found here or as a pdf.

We meed first Friday of the month (unless otherwise specified) at Birnie Village Hall. Doors at 7pm for a 7.30pm start.

Not a Member? Why not come along as the first meeting's free so you can 'try before you buy'.

Club members can also attend the meetings of the Highlands Astronomical Society (HAS).  Details of forthcoming meetings of both can be found in the Whats On section of this website, or download a copy of our 2017 Leaflet (pdf).

You can also follow SIGMA on Twitter and Facebook to keep up to date with our latest news.

Alan has captured more noctilucent clouds - look closely and you can see The Plough constellation as well.
