Gravitational Waves Detected From Betelgeuse? Did It Explode?

hello wonderful person this is Anton and in this video we're going to be continuing talking about the famous star known as Beetlejuice that you can see right there in the night skies of our planets a few more interesting facts just came out about the star and one of them involves gravitational waves so let's talk about baru's once again and welcome to what math the incredibly large beautiful and bright views that you see right there in the middle is technically known as the arm of Orion in different languages and we reduce itself stands for the arm of Orion in Arabic this star is so extremely large and expanded so much over the years that it can easily be seen with a telescope and with the powerful enough telescope you'll even be able to see something like this the actual features will become visible as mentioned in some of the previous reviews if you were to place this star in the middle of our own solar system it would sort of look something like this covering pretty much most of the terrestrial planets and reaching almost all the way to the orbit of Jupiter with the radius that's about 900 times the radius of our own Sun so this is a tremendously large very bright and very powerful star but the thing is on January 14 of 2020 something very unusual has been reported by some of the scientists working for LIGO which is of course this large l-shaped detector that was responsible for detecting gravitational waves on various black holes and neutron stars collided allowing us to study effects we've never been able to study before you can actually even see this report yourself on the so-called Greece database that keeps track of all the gravitational waves and has a really accurate up to date approach to post in all of the great Asian ways pretty much as soon as they're detected so here on January 14 of 2020 these scientists reported detecting unusual gravitational waves coming from the same region where the Orion constellation is located and because this was only a few weeks after we detected the demon's effects this obviously raised a lot of interesting questions is Betelgeuse actually going supernova did it finally explode and are we observing some unusual effects including the gradation of waves that we think some supernovae might produce and according to the LIGO researchers this is the unusual burst way of gravitational wave that we don't really have a good explanation for so technically it could have been an actual explosion or a supernova but at this point we're not even sure if this is a real detection or if it's something related to a disturbance here around earth that might have created this as well because like Oh is so sensitive that it can technically detect things that are created by also of mechanical and electrical things on the planet in other words for now this report is very preliminary but a lot of scientists studying below Jews were super excited and some of them even went outside to check if it's still there because maybe it has gone super Noah and as of today at least the last time I checked it's still there it still hasn't exploded and one of the astronomers Andy Howell has even gone as far as making a small map showing us where Betelgeuse is and where these two detection are in relation to beetle use in other words he kind of demonstrated that there weren't really exactly where the Betelgeuse is they could have come from any other region here and here but just the fact that we've detected a gradation wave so soon after we start reporting the diamond effects of Betelgeuse is exceptionally unusual and I guess in some sense a very crazy coincidence but today I think most scientists would agree that it still has probably a few thousand possibly even hundred thousand years in it before it actually does go supernova currently Betelgeuse has existed in this form as a giant for roughly around 80 thousand years but it still has way way more to go but furthermore one of the new models that was recently posted because Betelgeuse suddenly became a very famous star to talk about again suggested something else really interesting it suggested that possibly Betelgeuse has even more than originally thought in other words it might not be going supernova anytime soon at all for a very simple reason over the last year's the scientists studying video just discovered that there are two and usual properties that it has one of them is that it seems to possess a tremendous amount of nitrogen that shouldn't really be here and the other is that it seems to be spinning way way faster than it should be spinning because it's such a tremendously large star as stars expand they should be slowing down their rotation they should not be spinning very fast will just however spins pretty fast possibly as fast as fifteen kilometers per second on the surface here and this presents another unusual problem that we can't explain but one of the recent studies try to tackle that and by using various models these scientists have been able to explain these unusual properties along with the origin of Beetlejuice relatively accurately so first of all we know today that it was very likely created in the this very dense star region known as Orion OB 1a and it very likely also got kicked out of here and moved all the way to where it is today we know this because Betelgeuse is actually moving relatively fast across the night skies and it's leaving this particular system but hypothetically if Betelgeuse was not one star but a binary system with two stars orbiting around one another in this fashion here and one star being about 16 masses of the Sun the other one being about four masses of the Sun once they got kicked out of this original home system their orbits would actually de stabilized a little bit and with time these two stars would slowly start approaching each other and eventually combine into one in other words these stars would turn from binary system to a singular large object that would then start mixing its material and also create a lot of spin momentum which would explain why the modern Betelgeuse is spinning so fast and also by combining the smaller star with the largest star some of the nitrogen that was already created here would have actually stirred up bringing it to the surface which is why we're seeing so much of it today in other words if the be reduced star was a binary system and was then merged into a single object it would actually have all these features that were observing today but on top of this if this is what happened it's very likely that it still has so much material in it that it shouldn't really be going supernova anytime soon as a matter of fact this new discovery or this new analysis suggests that might have overestimated when Betelgeuse is going to go supernova this scientists behind his paper now think that it actually is not going to preneur for a very very long time and this particular idea makes a lot of sense as a matter of fact we already know today that some of the unusual peculiar observations we have of stars can usually be explained if the star itself used to be a binary system like for example very recently i've talked about the g objects and today we know that these unusual g objects that otherwise are very difficult to explain can be very easily explained if two stars are merged to create the object that we are observing so in a sense the binary system becoming a singular star can explain meaning different phenomena we're observing today and this could of course apply to Betelgeuse as well but we need the water follow-up studies for this to become a fact for now it's just an assumption although a very sound very scientifically accurate assumption assumption that I personally really really want to be true but we'll find out with time if this is correct and the thing is if this was a binary system that became a singular star this could be our best opportunity to study the evolution of such unusual systems in other words by studying what's happening with Betelgeuse and trying to understand what effects this has on the actual star system we might be able to then create a lot of other ideas and a lot of other theories to help us explain other mysteries in the universe specifically related to like for example dimming stars like the tabby star or other unusual phenomena that are currently unexplainable to us but anyway that's kind of it for the updates of villages so first of all with the tech degree teach new ways and secondly you we also think that maybe just maybe this used to be two stars in which case it still has all a few left before it becomes a supernova but on that note that's really it once we discover more about Betelgeuse and once we discover more about binary stars become singular stars I'll make sure to follow this up with another video until then thank you so much for watching subscribe if you still haven't share this with so many who loves to learn about space and Sciences and most importantly come back to more to learn something you may have not known before possibly even support the share of each one because it does help me quite a lot I'll see you tomorrow space out and as always okay
