Betelgeuse Explained

At the beginning of 2020, the world held its collective breath as a nearby behemoth star, called Betelgeuse, start to dramatically fade. Could this mean the star is about to go supernova? With the recent flutter of news activity settling down, we are now finally starting to understand what might have really happened. Today, we take a deep dive into what makes massive stars like this tick, and then get into how we might have now finally come up with answers to this bizarre event.
An educational video written and presented by Prof. David Kipping.

I'd go even farther than that, there's plenty of working physicists who post KZbin shows or lectures (or TV documentaries or whatever), but being a science educator takes a different skillset than being a scientist, and they don't always coincide. Possessing both skillsets is what separates folk like Sean Carroll or Mr. Kipping from the rest of the crowd.

Recently, several articles have been written about Betelgeuse dimming and the conclusion that has been reached is that a large cloud of dust moved between the star and Earth. That is why Betelgeuse’s brightness in infrared hasn’t changed. Infrared light will pass through clouds of gas and dust without being affected much. As professor stated, iron (element 26 on the periodic table) is the end of the fusion chain in a star. No element higher on the periodic table can be made in a star. The only way heavier elements are created is in a supernova explosion. The heaviest element being uranium (element 92), which is why it is the heaviest naturally occurring element on Earth. Silver, gold, platinum were all created in a supernova. But the iron in our blood and the core of the Earth came from a stellar core (maybe supernova too). This is direct evidence that another star went supernova, blew out its guts, and those guts became the seeds for our entire solar system including creating another star, our sun. The only question that remains about that event is what happened to that progenitor star?

[@jlo13800]

betelguese burns 2 stroke fuel oil!

[@jameshall1300]

Sorry to necro your comment, but the current consensus is that most of the elements heavier than iron were actually created from the collision of neutron stars. There apparently isn't actually enough of those elements around to conclude that supernovae are the primary source. They'd be far more abundant if so.

[@jlo13800]

[@cuttheknot4781]

The Sun is 8 light minutes away from Earth which is 1 Solar distance away. If the Sun were 1 light year away from us it would then be 65,000 solar distances away than currently. If the Sun were 640 light years away ( as in Betelgeuse's case) the our Sun would be 41,600,000 times further away than it is currently. Would we be able to see out Sun then? No, and not even (in my opinion) if it were 1400 times larger as is the case with Betelgeuse. So how can we see Betelgeuse with the naked eye? Please try to ponder these proportions and distances. The brightness difference is no real consideration to make up the discrepancy, here. Please consider that I know only what I found on the internet with respect to distances, sizes, etc of this star. Also, I know very little about such things. However, I cannot see a way to visualize this star with the naked eye if I am even remotely close. Thanks for indulging my ramblings. Keep safe, folks.

@@cuttheknot4781 The furthest star we can see with our naked eye is about 4000 light years away, thats. 6-7times further away than Betelgeuse. Obviously size makes a difference, but its not really a matter of opinion whether a star is visible, its just physics and maths. If you look up into the sky in perfect conditions, you will see about 2000 stars with the naked eye. Considering we can see 4000 light years, some will lie further than 600 light years.

It would be such an important moment in modern human history. So many people have never really taken the time to look at the night sky. So many people lack amy appreciation for the universe we live in.

Love this presentation of massive stars that we have come from. Thinking a new star like our Sun could be created from the remnants of a giant star is mind blowing. Thanks for all your work.

[@science.madesimple2000]

Yes, the process of star formation is a fascinating and complex process. It is thought that new stars can form from the remnants of previous generations of stars, such as when a giant star collapses at the end of its life and forms a dense, compact object known as a neutron star or black hole. These objects can then serve as seeds for the formation of new stars, as they can pull in and compress nearby gas and dust, creating the conditions necessary for star formation. In addition to forming from the remnants of giant stars, new stars can also form in other ways, such as when clouds of gas and dust in the interstellar medium collapse under their own gravity. The resulting disk of material can then contract and heat up, eventually forming a new star. Regardless of the specific process, the formation of a new star is a momentous event, marking the beginning of a new chapter in the life cycle of the universe.

Andrew Cary sr thanks! I personally really get a kick out of going deep into a topic, beyond the headlines. We rarely chase the news cycle because it’s too reactive to go in depth usually, but this case tied nicely into some fundamentals about massive stars that is often omitted
