Betelgeuse Is Destined to Explode as a Supernova…But When?

Betelgeuse Is Destined to Explode as a Supernova…But When?

Long considered one of the brightest stars in the night sky, Betelgeuse has begun to dramatically fade then brighten again for reasons we can’t quite pin down. And it’s caused some people to wonder if it’s about to explode.

Long description:

Despite being roughly 643 light years away, Betelguese is nearly impossible to miss. For starters, it’s MASSIVE; so big that if it were at the center of our Solar System, it would engulf all the planets up to Jupiter. Its diameter is roughly 1,000 times that of our Sun! To find it, just look at the Orion constellation. If Orion is “The Hunter” with his iconic three-star belt, then Betelguese is the hunter’s left shoulder. If you’re in the Northern Hemisphere during the first few days of January, you can see Betelguese rising in the east just after sunset. All other times, this star is easy to spot no matter where you’re located in the world! Especially September through March.

Some of the earliest known records of Betelguese come from China in the 1st century BCE. These records describe Betelgeuse as being yellow… which is strange, because just a few years later, in 150 CE, the Egyptian astronomer Ptolemy described Betelguese as red. This indicates that Betelguse rapidly underwent a stellar phase change sometime between the time these two records were made, evolving to become the red giant that it is today.

Betelguese’s propensity for fading and brightening over a multi-year cycle also seems to have caught people’s attention. In western Aboriginal Australian oral tradition, Betelguese represents the ‘fire magic’ used by a love-struck hunter to reach the object of his affection. Unfortunately, the fire magic’s tendency to flicker out ultimately causes him to fail. While Sir John Herschel continues to be recognized as the first to notice Betelguese’s variable brightness, it’s clear that people living before the 19th century also recognized what was going on.

Betelgeuse went dark, but didn’t go supernova. What happened?
“What they do know is that Betelgeuse is running out of time. It’s less than 10 million years old, a youngster compared with the roughly 4.6-billion–year-old sun. But because Betelgeuse is so massive and burns through its fuel so quickly, it’s already in the final life stage of a red supergiant.”

Aboriginal Australians Observed Red Giant Stars’ Variability
“Hamacher found two oral traditions that referenced the variable stars Betelgeuse, Antares and Aldebaran. Their changes in brightness carried important weight in the narratives and helped encode certain social rules, such as signaling to the tribe when to celebrate initiation rituals.”

When Will Betelgeuse Explode?
“In this video, I talk about when Betelgeuse will explode. Spoiler: it’s not for another 100,000 years or so! I discuss the physics of the recent dimming and subsequent brightening, and what we can see when we look up with the naked eye.”

You can probably point to the Big Dipper, Orion’s Belt, and your astrological sign in the sky. But what would the constellations look like from another solar system? And will any of Orion’s stars ever become black holes? In Seeker Constellations, we’ll explain the science of the universe’s most famous stars and dive into the culturally significant stories behind them. Most importantly, we’ll provide a guide to where you can see these incredible constellations for yourself!

Seeker empowers the curious to understand the science shaping our world. We tell award-winning stories about the natural forces and groundbreaking innovations that impact our lives, our planet, and our universe.

  1. if u wont listen or learn men gtfo all of u just comment on her looks stfu. also the other people making these videos eat to multiply ur brains cells instead of using other peoples studies

  2. Is saying that Betelgeuse is destined to explode actually a scientific statement? Saying that it isn't destined to explode would be falsifiable because if it did explode the prediction could be falsified. However, the reverse isn't falsifiable so it's actually pseudoscientific, i.e. it sounds like science but it isn't.

  3. I never saw this thing in the sky ever. So fun living in an modern country like holland.

    Jk i love my country and im grateful but we are so disconnected from the natural world by visual lack of the ✨

  4. This was an awesome video and I loved the presenter. Seeing someone presenting their research and passion is great. More of this please!!!

  5. The scary thing is because light from that star takes 642 light years to reach us it could very well have gone supernova by now it’s just that it might take a couple hundred more years for that supernova light to reach us

  6. What she means to say, is they have no idea what's going on in space so they use 'educated guesses'. These people don't know nearly as much as they would have us believe. With the billions of stars out there nobody has seen not even 1 form. Why is that? Look to your heart and the Creator is the answer.

  7. Most stars are destined to explode in a supernova…. Betelgeuse isn’t going anywhere anytime soon. A new study shows that if Betelgeuse used to be a binary system and the stars merged, it explains features and behavior of the star better than assumption it’s about to go supernova. It’s more likely it’s not about to go supernova. The spin, size and behavior of the star suggests it’s a merged binary system.

    Like most science, it’s only a matter of time before what we once thought to be true is proven to be false. It’s the nature of learning. The more we learn the more we have to learn. Each discovery opens up more questions that it answered. This is why I hate when science topics are politicized or major decisions are made based around science we can’t actually run experiments on to know for certain like the past and the future. We can only make our best guesses. People need to stop presenting things as “facts” when they aren’t facts. There should be a disclaimer that what is said is only our best guess with the extremely limited knowledge and understanding we do have.

  8. Get ready for some of our amazing world to change with this new data. There is so much to learn from this star. We will still have many things to learn from this event as a people.
