Good afternoon, Rallypoint, and welcome to the October 13th edition of Astronomy Picture of the Day (APOD): "Dust Shells around WR 140 from Webb." Wolf Rayet (WR) stars have unusual spectra showing ionized helium and highly ionized nitrogen or carbon. So when the Webb telescope turned its attention to WR-140 in the constellation Cygnus (The Swan), a series of carbon-rich dust rings were revealed.
The presence of WR-140 explains what produces the dust. But what about the ring structure? WR-140 has a companion star that completes an orbit every eight years. Scientists have noticed that x-ray readings increase as the stars reach their closest approach to each other. A current theory suggests that as the radiation increases, so does the dust - producing another ring. By my count, we can see some 150 years (19 rings) of data in this image.
WR-140 lies about 6,000 light years from Earth.

Thank you my space-exploration advocate friend Maj William W. 'Bill' Price for posting the October 13, 2022 Astronomy Picture of the Day (APOD): Dust Shells around WR 140 from Web

The wonders of the creation by the LORD in the heavens are beautiful and wonderous.
APOD "Explanation: What are those strange rings? Rich in dust, the rings are likely 3D shells -- but how they were created remains a topic of research. Where they were created is well known: in a binary star system that lies about 6,000 light years away toward the constellation of the Swan (Cygnus) -- a system dominated by the Wolf-Rayet star WR 140. Wolf-Rayet stars are massive, bright, and known for their tumultuous winds. They are also known for creating and dispersing heavy elements such as carbon which is a building block of interstellar dust. The other star in the binary is also bright and massive -- but not as active. The two great stars joust in an oblong orbit as they approach each other about every eight years. When at closest approach, the X-ray emission from the system increases, as, apparently, does the dust expelled into space -- creating another shell. The featured infrared image by the new Webb Space Telescope resolves greater details and more dust shells than ever before."

I put this together from a variety of sources of variable quality, some of which was originally silent, and synched it with the version of the song performed...

Cowboy I just got this from my Senator.
Why a Social Security Roundtable? As mentioned above, Bidenflation has ravaged America since 2021as a result of the change in policies pushed by Biden and the radicals in congress. Unfortunately, these reckless policies have hit Arizona the hardest. Arizona has a large percentage of retirees. Inflation risks severe harm to their ability to maintain their lifestyle.
Because of raging inflation, the 2023 cost of living adjustment (COLA) of 8.7% is the highest since the current automated formula was put in place in 1983. While this necessary bump will help seniors going forward, seniors have already been facing, and will continue to face these sky-high prices. Additionally, the high COLA could push many seniors whose benefits weren’t previously subject to taxation to pay taxes on their benefits for the first time and saddle others with a higher tax bill
