2014 Christmas Party

12 December 2014 is our annual Christmas Party and this year the public is invited. Our members will be displaying their telescope equipment and accessories and will be available to answer questions about this astronomical equipment. If you’ve been thinking of buying a telescope as a gift for someone or even for yourself, this is a great opportunity to get information you need to make an informed decision. Meet us at 7:30 PM at the Sunshine Coast Arts Centre, 5714 Medusa St, Sechelt.

NOTE: SCC RASC members are requested to attend at 7 PM for a special meeting. Public will not be admitted until 7:30 PM.


Second Taping Session for Night Lights TV Show

On Friday, 24 October, Mike, Garth, and Charles took to the Elphinstone Secondary School studio of Coast Cable to shoot more footage for upcoming episodes of our Centre’s Night Lights TV show. On Wednesday, 29 October Charles will head to Vancouver with Coast Cable to shoot more footage at the MacMillan Planetarium, Southam Observatory, and Vancouver Telescopes.

Solar Eclipse October 23: Glimpses Through the Clouds

It poured with rain most of the day on the Sunshine Coast but in the afternoon there were a few brief gaps in the clouds. I was up at Chatelech Secondary School with a Coronado hydrogen alpha and we had two holes in the clouds which gave some students a view of the eclipse in progress. Some of our other members got glimpses from other locations. Ed Hanlon shared this picture he snapped through a hole in the clouds.


X1 Solar Flare

Our Dr. Garth Jones just called to let us know that there is a huge sunspot AR2192 and the X1-class solar flare it unleashed. Check out the current (Sunday, Oct. 19) version of — News and information about meteor showers, solar flares, auroras, and near-Earth asteroids

Dr. Stairs Interview

Our president Mike had a chance to interview Dr. Ingrid Stairs following her presentation on pulsars at the Gibsons Public Art Gallery on 10 October:

Our Speaker for November 2014: Dr. Douglas Scott

scott_douglasDr. Douglas Scott, a professor of cosmology at UBC. Scott got his Bachelor’s Degree in 1986 from the University of Edinburgh, and his Doctoral Degree in 1991 from the University of Cambridge. Scott was a Postdoctoral Fellow at the University of California, Berkeley from 1991-1995 and has been a UBC Faculty member since 1995. His specialty is cosmology and he does research in structure formation, cosmic microwave background, early universe, high redshift galaxies, and sub millimetre observations. On his web site he tells us:

Physical Cosmology can be split into 2 major branches: the detailed study of how structure formed; and the investigation of the parameters which describe the entire Universe. My research involves several different parts of both of these branches.

The most extraordinary thing that we have been learning about cosmology in the last few decades is that there are things we measured which can give us direct answers to questions about the large scale nature of the Universe. Right now these quantities are being measured and we are in a period of rapid growth in our understanding of cosmology. Many of today’s questions appear answerable on a timescale of years – and this is what makes cosmology currently so exciting!

We know that the Universe has close to flat geometry, and is dominated by a mysterious dark energy, with most of the matter also made of some as yet unknown form. The early Universe was very smooth, with low amplitude density perturbations of the sort generated in the inflationary picture of the early Universe. And we know that those perturbations grew through gravitational instability to make all the structure that we seee in the Universe today. Galaxies are the fundamental building blocks of this structure, but the details of galaxy formation are not yet understood, because it involves a huge range of physical processes on a variety of length scales and time scales.

Measuring the dozen or so cosmological parameters cannot typically be done without also measuring quantities that depend on galaxy formation and evolution. Hence the study of the two main branches of cosmology are always intimately connected. With the parameters being measured to greater and greater precision, and the physics of galaxy formation being dissected in ever increasing detail, we are still left with many unsolved puzzles. In particular: why do the parameters have the values that they do? what are the dark matter and the dark energy? did inflation really happen and can we learn anything about it? are there basic ingredients currently missing from the standard cosmological model? when exactly did the first stars form to end the cosmic dark ages? what is the relationship between supermassive black holes and the galaxies that they form inside? what will be the far future fate of the Universe and of our small part of it?

The development of structure in the Universe is a complex and multi-faceted topic. Tackling the biggest questions in the formation and evolution of galaxies and clusters of galaxies requires a combination of observational and theoretical approaches, covering the full range of the electromagnetic spectrum. A crucial and developing window is in the sub-millimetre part of the spectrum, where one can readily study star-forming galaxies at very early times. Because of this I have become involved in several projects and instruments which focus on using these wavelengths in order to conduct ambitious, deep extragalactic surveys.

Dr. Scott will be doing a talk on his work with the Planck satellite. Join us to greet him at the Sunshine Coast Arts Centre, 5714 Medusa St, Sechelt, BC, at 7:30 PM on 14 November 2014.

Dr. Scott’s talk is: “Planck, the Universe, and Everything”. The Planck satellite has completed its mission to map the entire microwave sky at nine separate frequencies. This enables us to learn about the physics of the interstellar medium in our Galaxy, and to remove this foreground emission in order to extract the cosmological information from the background radiation. Planck’s measurements lead to an improved understanding of the basic model which describes the Universe on the very largest scales. And although we can now define the Cosmos in terms of a few basic assumptions and a handful of numbers, of course many questions remain unanswered. Planck analysis continues, with the release of polarization information expected before the end of 2014, enabling new science issues to be addressed.

2017 Total Solar Eclipse


While eclipse chasers pack up and travel to various parts of the
world in search of a total solar eclipse under clear skies, we north
Americans will have one within a days drive in 2017. The date is
August 21st and the path of totality carves an east to west path
right through central Oregon. Being right on the eclipse path in
Oregon will give you about 2 minutes of totality. Depending where you
are in Oregon the eclipse will start around 9 am, end at 11:40 am with
totality around 10:20 am. This means getting there at least the day before.

Star party goers might consider that the Oregon Star party dates in
2017 coincide with the eclipse and the star party site is located
either in or very close to the path of totality with the center line
being about 2 hours drive north of the star party. With this in mind
OSP organizers are planning for there biggest year ever at the star party.

Its never to early to plan for an event of this magnitude and Hotels
in Oregon are already reporting requests for eclipse bookings. My
advice to those willing to travel to this once in a lifetime event is
to book soon because the city’s closest to the path will gradually
book all up and accommodation close to the center line will be harder to find.

Address of our Milky Way Galaxy

Dr. Garth Jones brought this piece of news to our attention. Scott Harlow commented:

“I found curiously ironic in that the title ‘Laniakea’ concocted by the astronomers disclosing this information from their research, and which translates from the Hawaiian as “immeasurable heaven”, is a name attributed by those people whose profession reduces to measuring “heaven”. Nice to know that subtle scientific humour is alive and well.”
