In one myth, Orion boasted he would kill all the wild animals on the earth. But, the earth goddess Gaia, who was the protector of all animals, produced a gigantic scorpion, whose body was so heavily encased that Orion was unable to pierce through the armour, and was himself stung to death. His companion Artemis was greatly saddened and arranged for Orion to be immortalised among the stars. Scorpius, the scorpion, was placed on the opposite side of the sky so that Orion would never be hurt by it again. To this day, Orion is never seen in the sky at the same time as Scorpius. DSO’s ● ***M42 “Orion Nebula” (Neb) with Trapezium A stellar nursery where new stars are being born, perhaps a thousand stars. These are immense clouds of interstellar gas and dust collapse inward to form stars, mainly of ionized hydrogen which gives off the red glow so dominant, and also ionized greenish oxygen gas. The youngest stars may be less than 300,000 years old, even as young as 10,000 years old (compared to the Sun, 4.6 billion years old). 1300 ly. 1 ● *M43--(Neb) “De Marin’s Nebula” The star-forming “comma-shaped” region connected to the Orion Nebula. ● *M78--(Neb) Hard to see.

We had a good time, and About 100 people (adult and children) attended. Ben Toman live streamed on the BRAS Facebook page. See his description in this newsletter. A copy of the proposed, revised By-Laws should be in your mail soon. Read through them, and any proposed changes need to be communicated to me before the November meeting. Wally Pursell (who wrote the original and changed by-laws) and I worked last year on getting the By-Laws updated to the current BRAS policies, and we hope the revised By-Laws will need no revisions for a long time. We need more Globe at Night observations – we are behind in the observations compared to last year at this time. We also need observations of variable stars to help in a school project by a new BRAS member, Shreya. -

As the name suggests, these objects have known luminosities by virtue of their intrinsic proprieties and play a major role in our understanding of modern cosmology. The main caveats associated with standard candles are their absolute calibration, contamination of the sample from other sources and systematic uncertainties. The absolute calibration mainly de- S.

The nights are starting earlier and earlier as the weather becomes more and more comfortable and all of our old favorites of the fall and winter skies really start finding their places right where they belong. October was a busy month for us, with several big functions at the Observatory, including two oppositions and two more all night celebrations. By comparison, November is looking fairly calm, the big focus there is going to be our third annual Natural Sky Conference on the 13th, which I’m encouraging people who care about the state of light pollution in our city and the surrounding area to get involved in. -

On June 21st, at 11:24 AM CDT, summer officially begins for the Northern Hemisphere. We have a lot of outreach requests for June; the July BRAS meeting will be our annual picnic at LIGO; and one week after the August BRAS meeting is the total eclipse of the Sun. What are your plans for the summer? Will you go somewhere to see the eclipse? The band of totality runs from Georgia across the continental US to Oregon. Last month we did outreach at the Bluebonnet Swamp’s FAE Fest/20th Anniversary event. Due to a cloud cover most of the day, there was little solar viewing, but we did interact with close to 300 people, including a former member of BRAS (about 20 years ago) who expressed interest in re-joining us.

This is one of several changes aimed at increasing the membership of the VSS. It is possible that, in the past, the relatively high cost of the Circulars has put some people off from joining. Also, I would like to be able to sell them at meetings for no more than 50p each without alienating the postal subscribers who would be paying more than twice that for their copies. The new subscription rates are given inside the front cover. Notice that they now differentiate between BAA members and non members. Any outstanding subs which you paid at the old rates will be convert ed to the new rates and you will receive proportionately more circulars for your money.
