This is normal for Betelguese and is likely the way things will be for millennia.
If Betelgeuse were closer to Earth, it would be a literal and figurative “”lights out”” for all of us. It wasn’t conclusive, but could something like that be happening on Betelgeuse, contributing to the dimming? Convection happens in the outer regions of most stars, including our Sun. […], Making science accessible on social media since 2017. Whatever the cause, we know what the eventual end for Betelgeuse looks like: a supernova explosion. Anything within 50 light-years of the exploding Betelgeuse will suffer massive shockwaves, and be inundated with dust and radiation. (wallet privacy). Betelgeuse is a red supergiant star in the constellation Orion. A Key Biosignature Called Phosphine has been Discovered in Venus' Atmosphere, Episode 683: Open Space 86: The Venus Announcement, and More…. Primordial Black Holes, Episode 687: Open Space 89: Scott Gaudi and the HabEx Mission, Episode 686: Q&A 129: Did Life Get a Ride to Venus from our Missions? It then cools and sinks into the star, and the cycle continues. We’ve also never been able to observe any other red super-giants the way we can with Betelgeuse. Since the CNO cycle releases more energy at a faster rate than the pp-chain, this means a star’s temperature increases over time. The explosion remains bright for around 100 days, since the radiation can escape only once ionized hydrogen recombines with lost electrons to become neutral again. Drawing a complete graph of 5 nodes on a torus. But it is now fusing helium so furiously that it has bloomed into a red supergiant. Nothing to see, better luck next time.

Betelgeuse has been the center of significant media attention lately.
Use MathJax to format equations. Gamma radiation, in particular, is incredibly powerful. Thanks for contributing an answer to Astronomy Stack Exchange!

BETELGEUSE.COM REGISTERED SINCE 1996. News 'Large spots' explain star Betelgeuse's odd dimming, scientists say.
What is it about Betelgeuse that allows us to say “not for another x thousand years”? How far from Betelgeuse is its habitable zone? ±100 000 years?”. The paper appears in the Astrophysical Journal. But the outer layer of Betelgeuse is much less dense than that of the Sun. That means the convection regions on Betelgeuse can be huge. Is this expected? What If Spinosaurs Were Still Swimming Today. Buy with confidence All transactions are completed via Escrow.com, the safest domain purchasing option. For the simple pulsation case, the team's model yielded similar results to the models that didn't account for pulsation. As the iron core collapses the atoms disassociate into electrons and protons. While both the pp-chain and CNO cycle can occur at the same time within a star, over time the CNO cycle increases as hydrogen become more scarce and helium more abundant. "It's when you start considering pulsations that are more complicated, where there's stuff moving in at the same time as stuff moving out—then our model actually does produce noticeable differences," he said. https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/, Astronomy Cast: I keep hearing this, but I wonder what the uncertainty is on these figures? We’re about 10 times too far away to feel any repercussions from the explosion. Betelgeuse, the red supergiant star that acts as the shoulder of Orion in his constellation, is having a moment. - TheXplorist.
