Thank you very much for this most informative video. I can see you done your research. You have a new subscriber. Amateur astronomer and armchair astronomer from England.

I have a theory of what causes the supernova. Three things control stellar fusion, heat, pressure and magnetism. The star produces a lot of iron which migrates outwards eventually generating it’s own magnetic field which undermines the main field causing instability and an explosion.

I thought it was my eyes starting go when I looked at betelgeuse a few weeks ago. It was noticeably dimmer

"Betelgeuse could go supernova any day to 100,000 years." Me: So you are telling me there is a chance?

Thanks for the video, I was VERY excited when I read the description that this might set up for the explosion of Betelgeuse, lol!!

I'm glad for visiting your channel

You already covered my thoughts on this Fraiser: C'mon and blow up already. I want to still be here to see it

The star has already gone Super Nova... 100's of years ago. I suspect that the dimming and brightening of certain stars (including UY Scuti) is related to the explosion of the Super Nova. The "backlight" of the explosion is the brightening effect... and the in between of the waves of the explosion are the moments it dims. The light from behind is being propelled at a faster rate due to the massive explosion and that light fades faster thus giving an off/on or up/down intensity effect of the light. Only the light from the initial moments before has been reaching us. Chances are, the star wasn't even as big as we calculated... rather, we might have calculated its size during the initial moments it was actually exploding. We have yet to see the fantastic light of the actual moment... and when it arrives it might last anywhere from 3 to 6 months. Also, we may have two other stars (which may have gone Super Nova around the same time) show up and stay in the sky with the light as bright as the moon. UY Scuti and Canis Majoris might very well all be in the sky for several months each overlapping in duration. Not sure when since there is no real idea when any of these could have already gone.

Having learned where to find it in the sky a few days ago, I gazed upon it last night, and noticed it was too dim for a super giant. However, this video confirms that, indeed, it has been dimming as a possible prelude to its final explosion. Wow!

Hi Fraser, is it possible to know what elements are being fused in the core of Betelgeuse right now, and thereby determine how close it is to the final stage, when it's producing iron?

@guytech7310

4 жыл бұрын

Not really, Fusion happens in the core which is millions of miles below the star's surface. I takes +100K years for light to travel from the core to the surface.

What if it already Exploded?! 640 Light years away from us. If we see the Supernova right now, it means it has already gone supernova 640 years ago.

Seeing Betelgeuse go supernova would be the thrill of a lifetime, but thankfully I’m still easily impressed by meteors streaking across the sky from time to time while out for my nightly walk on a dark stretch of beach.

OMG!! I've noticed the same thing last week. It appears less reddish than it's used to.

14th Century would be 1301 to 1400 - at 640 light years that would be 1941 to 2040 - we could have known of a supernova from 1941 to now

Perhaps its because the star has moved on to another element to fuse. Not the supernovae inducing iron, but maybe Calcium or something. An element where the fusion of it has a lower exothermic output as the previous elemental fuel.

Hi Fraser, question for your next Q&A: Do you think we would be able to attach a probe to a future interstellar visitor like Borisov or Oumuamua? We could utilize its speed to explore deeper into interstellar space.

Seeing a supernova in the sky would be quite cool. Almost as cool as a total solar eclipse, which I have yet to see. But the first I read of this was one of those typical cheap headlined articles that are there just to get you to click. At least this video isn't titled "Betelgeuse is dimmer and might..." Good information is good. Clickbait erodes cognizance and ticks me off.

My Destruction-Warlock's name was Betelgeuse in WOW :D (many years ago)

Maybe I missed it, but wouldn't we be able to see an increase in iron analyzing Betelgeuse's light spectrum?

"when it explodes" it could have already exploded a long time ago. Keep in mind that what we see has happened a very long time ago and light doesn't travel instantly, so when you are looking at a distant star you are not just looking at a star you are looking at possibly thousand of years of history that has just reached us and could even be a star that have died a long time ago in an event that is still traveling its way towards us
