UM-Bot Posted June 11, 2021 #1 Share Posted June 11, 2021 The star, which is 100 times the size of the Sun, underwent an extended period of anomalous dimming. https://www.unexplained-mysteries.com/news/347692/huge-blinking-star-spotted-near-galactic-core 2 Link to comment Share on other sites More sharing options...

Tom1200 Posted June 11, 2021 #4 Share Posted June 11, 2021 5 hours ago, DreadLordAvatar said: Dyson sphere. We are not alone. They're 25,000 lightyears away. We're effectively alone... I love the last line: "It is thought that the disc could pass in front of the star again within the next 20 to 200 years." An utterly worthless 'prediction' based on no available evidence that adds nothing to the story. I'll add my own pointless contribution: "It is thought a different disc could pass in front of the star again within the next 20 to 200 years." There - I'm now an astrophysicist! 2 1 Link to comment Share on other sites More sharing options...

Ell Posted June 12, 2021 #7 Share Posted June 12, 2021 (edited) The disk explanation appears contrived. I do not believe it. That said, I cannot provide a more probable explanation for 97% of dimming during several hundreds of days. It is an interesting phenomenon. :-) Hm, the star may have puffed out a dense sphere of dust during a hundred days, blocking its light. As the sphere expanded during the next hundred days it became transparent to the star's light again. Plausible? Edited June 12, 2021 by Ell Added a hypothetical explanation.

Eldorado Posted June 17, 2021 #8 Share Posted June 17, 2021 Stars may twinkle, but they don’t just vanish—so when a distant, giant star pulled a disappearing act for about 200 days, it took astronomers by surprise. Now, roughly a decade later, astronomers have sifted through a variety of possible explanations—and they still have no idea what’s responsible for blotting out nearly all of the star’s light. Described in a new study in the Monthly Notices of the Royal Astronomical Society, some of the theories still on the table rely on as-yet unobserved phenomena, such as a dark disk of material orbiting a nearby black hole, or undiscovered, dust-enshrouded companion stars. But over 17 years of observations, the star has only gone dark once, in 2012, making it more difficult for teams to nail down a plausible culprit.

Essan Posted June 17, 2021 #9 Share Posted June 17, 2021 I think that it's very possible that the dimming of Betelgeuse may be due to the Great Collapsing Hrung Disaster Obviously if anyone knew what a Hrung was and why it should choose to collapse on Betelguese VII we would know for sure. 1 Link to comment Share on other sites More sharing options...
