At 7:30 PM, 11 January 2019, at the Sunshine Coast Art Centre, 5714 Medusa St., Sechelt, the Sunshine Coast Centre of the RASC presents Paul Gray, the editor of the RASC Calendar, who will be doing a presentation on Dark Nebulae. A dark nebula or absorption nebula is an interstellar cloud so dense that it obscures the light from objects behind it, such as background stars and emission or reflection nebulae. Interstellar dust grains, coasted with frozen carbon monoxide and nitrogen, in in the coldest, densest parts of larger clouds effectively block the passage of light at visible wavelengths. These clouds are the spawning grounds of stars and planets, and understanding their development is essential to understanding star formation.
The largest dark nebulae, like the Coalsack Nebula and the Great Rift, are visible to the naked eye, appearing as dark patches against the brighter background of the Milky Way.
Admission is free: donations gratefully accepted at the door.
Last night (Saturday, 1 December), We conducted a training session at the observatory and Shannon McLaughlin completed her training as Qualified Operator. Ed Hanlon came later and went through some of the training, but we were losing the sky by that time, so he’ll come back and complete the QO course later.
If you’re interested in learning how to use the observatory telescope, please contact me. We’ll take you through the procedure of opening/closing the observatory, starting up and parking the telescope, navigating the night skies with the telescope, and recovering from telescope failures to get back into action quickly.
