It is being observed across many EM wavelengths, including the infrared. As a matter of fact, observations in the infrared during the dimming in 2019 (in the visible spectrum) remained steady, so the dimming wasn’t in the infrared, just the visible light part of the spectrum. If I remember, Hubble does have some capability in observing in 5he near infrared.

I HAVE BEEN WAITING FOR THIS EXPLANATION Back in November I recorded a super zoomed in video of Betelgeuse in an area with little to no light polution, in the video I acknowledge just how crazy bright it is and that it's flashing blue and red. You can even make out the bubbly effects in the video, I did not even think astronomers were studying Betelgeuse right now because the last thing NASA reported on it was that it dimmed significantly and went from being the 10th brightest star to the 20th something which was back in 2019, and now it's even brighter than it was when it was the 10th brightest star, so essentially I spotted and recorded Betelgeuse's bubbles AND the fact it got so much brighter - months before NASA even reported these things, and for that I am very proud of myself, as soon as I went inside home after making the recording, I tried as hard as I could to find any news about the stars current state but the latest studies on the star were in 2019 so I never was able to find any explanation...until now

Beetlejuice is a giant waste depository for toxic waste generated by the artificially created stars used to power the hyperloop slip stream gates to traverse the galaxy by exiting local space time and traveling outside the curvature of the 3rd dimension of our universe and local time flow is stopped while outside the confines of space time, in the foamy environment of the higs field where the multiverse can be observed and quantified, before you pop your gravity bubble and the graviton waves push you through the space time membrane , back into our own universe that we can exist in. Most universes in the multiverse lack the necessary constants and energy needed to support biological so called life. Were we to accidentally poke a hole into the wrong universe, we would evaporate into basic sub atomic particles and cease to exist. So if could give me a lift to Saturn, I can gather enough materials and deuterium from the wrings to build my own gravity slip stream to access the higs field and get back to my dimension hopefully without being pushed into the wrong universe again. I'm tired of the clown universe of evil and chaos. It was fun the first couple millennium, but its still the clown universe and I hate clowns. Get me the hell out of here. I also can make your interdimentional gravity drive operate more effectively and prevent accidental disentanglment and quantum evaporation and other types of interdimentional errors and potential fuckery that can cause unwanted non existence and cascading universal ripples and mergers with unstable universes like clown universe. So come pick me up, and then we can go back to the universe of order, harmony, and swarms of winged nympomaniac super model hookers and portable blow job maidens . You know , those hot chicks with no vocal chords and a desire to be naked every time they see a star ship land. Clown universe sucks and has none of the great stuff found in the orderly universe we were robbed from. Get me out of here

I’m just amazed how scientists are able to figure things out with just a fuzzy image of a light.

Damn... I remember the good old days when Ford, Zaphod and I used to star surf on Betelgeuse... I hope they are alright wherever they are...

I can already see the headlines if it goes nova in the near future: “Betelgeuse breaks physics”, when really, we had no idea what would really happen to begin with. This is why we need to be careful about using the word “theorize”, when colloquially we mean “speculate” or even “estimate”. Whatever happens, I would bet that it will completely surprise the science community.

It's deathbed,lol, maybe 500,000 years from now, these distances and time scales are so vast.

We've never observed a star forming. But they explode every 26 years on average. And we've observed that. So when someone says a star formed in a solar nebula. That's just an educated guess. Another interesting thing is if we count the exploded stars in our galaxy there are about 6000 years worth of dead stars.

The models of supernova's show that a star has to go through this boiling bubbling process first before it can explode. The models just don't work to produce a supernova without this happening. Doesn't mean the models are right but that is what they show. There is still a very small risk of a gamma ray burst from a Betelgeuse supernova despite being 650 light years away. It is almost certainly not big enough to produce a gamma ray burst and its explosion poles would have to be pointed directly at Earth but there is still a one in a billion risk. You would have to be in a concrete type basement for a few hours to escape this risk and everyone in your hemisphere would be dead on the streets anyway if it happened and there would be no electronic equipment left intact (including your car and your phone and electricity) so don't worry about it. You don't want to live through a gamma ray burst.

Making lightshift "observations" of something 724 lightyears away is like looking at a flea on Pluto and declaring which of its balls is closer to earth. By the way, Betelgeuse has forever been going supernova "any minuet now over the next 100,000 years" Believe what you will

Given the size solar flares .it's core has had time to age which will mean trillion s of tons of high grade gold

What kind of rotational speed is listed in km/s ? RPM, sure; radians per second, sure; km/s ... not so much! Now if you were talking surface velocity, which is fine for a hard surface like the surface of the Moon or Mars or Earth, but is kind of hard to apply to a bag of gas like Jupiter or the Sun. But, either way, if you meant surface velocity, say surface velocity.

It takes 700 years roughly for light to travel from Betelgeuse to Earth.

De ster draait sneller omdat ze groter wordt en onder invloed van de nabijheid van de andere planeten gaat ze meer graviteit maken en aldus veel sneller draaien.

How does getting closer to planets accelerate a stars rotation? Rotation impulse is maintained throughout its entire existance, and actually, the bigger an object, the slower it rotates with the same rotation impulse.

At first i thought the thumbnail was a delicious biscuit.

“ It’s show time “ !

Surely its "Something weird WAS happening on Betelgeuse"? Whatever we are seeing now is about 724 years old isn't it? So it may have gone supernova or whatever in the year 1299 and we wouldn't know until next year.

You mean something weird happened in the 14th century CE that we are just seeing now.

I thought the last visible supernova with the naked eye was the 1987 detection in the Large Magellanic Cloud; Still part of our Local Group.

Correct, it was visible. But the LMC is at a safe distance 168,000 light years away. Betelgeuse is in our back yard.....almost in our kitchen......a mere 700 light years away.

@@petergibson2318 Indeed. My post was in response to the commentator saying the last supernova visible to the unaided eye....albeit he did say in the Milky Way; but you are correct about the LMC. I believe it was only visible from the Southern hemisphere.

I'm under the assumption that it won't go super nova it will just go nova Am I wrong?
