“… and even if it exploded today we would not know about it for 700 years”. But what if it exploded 699 years ago?

That is the point. We assumed it was thousands of years away. Now it is a matter of a few hundred and could already have happened.

Exactly 💯

NASASpaceNews has some of the most beautiful/ stunning graphics on the entire web. Art and science blended magnificently. Thank you!

The neutrinos from Betelgeuse would most certainly penetrate our atmosphere. But, as usual, we'd not even notice it unless we've got our own neutrino detectors. Unfortunately, my large hill mass neutrino detector is in the laundry.

It was driving me nuts wondering y beteljoose was getting dimmer and dimmer since the last few years I’ve been observing it ! Thank yu for the xplanation !

Great video as usual 👍 any plans on making an episode about webbs observations of HR8799 ?

Point of note referring to about 4:25 into the video: 25 times the diameter of Earth is 318,550 km, not 37 million km.

Finally, someone who can pronounce Betelgeuse properly, thank you 🙏

My question would be what would happen to the Constellation Orion, if the topic star were to go super nova? How close together are the other stars that actually make that constellation or others that we can see with our naked eyes without telescopes?

The distances are huge, and the stars have vast Variation in depth. it is not a planar surface as it seems when looking into space. No risk for the other stars

This is just perspective. Think of it like movies where they do punches. from the viewer it looks like the punch but in reality there are not that close.

Great thanks

Thank you, very much. I love it🤩🥰🥰🥰🥰

*Wikipedia* says possibly as close as 499 light-years. Even at that distance, no danger to us or Earth.

Thank you.

I have heard that it could be now, thousands of years, or millions of years. That's one way to cover all probabilities.

That's an accurate statement. We can't observe the core of Betelgeuse, and without an observable companion, we don't even have accurate measurements of its mass (mass ~16-19 Suns), size (700-900X the diameter of our Sun), distance (500-650 L.Y.) nor its luminosity (60,000-130,000 X Sun). In "theory" (more like a hypothesis at this point) there might be some potentially observable brighting/dimming cycles toward the end of the Carbon fusing phase, that Betelgeuse "might" be showing, that "could" indicate Betelgeuse may run out of Carbon at the core within decades and explode as a Supernova in less than 100 years. Dr. Becky has a nice short discussion of this here: (the hypothesis starts ~12 minutes into the video) kzread.info/dash/bejne/ZYWbrtmppaetmKw.html

It is amazing

Thank you for your explanation - but I am a little bit disappointed, since I have hoped to see a supernova in my lifetime …

You’re killin’ me smalls! It’s Beeeeetlegeuse. Baytle juice is a drink popular in upscale San Fran drinking establishments.😂

2:07 "baytal-goose" okay

If neutrinos were detected from SN1987a certainly we'd detect them from Betelgeuse.

You used two pronunciations: Betel-juice and Betel-goose. Which is it?

I prefer to use the first variant becouse it is the nearest prinunciation to arabic way. I would like to say that I studied the problem of nomination in astronomy when l was a student and realy i saw many problems that deal with stars names. My best regards for every one.

I’m not exactly sure how it works but couldn’t we point JWST right at it and see with better resolution

@stanimal8

Don't think JWST has higher resolution than SPHERE (interferometry), but JWST can observe deep into infrared, which SPHERE can't do, due to Earth's atmosphere blocking most IR radiation.

I prefer the pronunciation "beetle-juice", just for fun! 😁

I observed the supergiant Betelgeuse through my telescope during the dimming period, and could see the huge dust cloud. It has brightened now, thankfully, and I’m quite happy for it not to go supernova anytime soon!

The other thing is, I live in Britain, and even though I am rural, we don’t get many clear nights for astronomical observing, and as I write this, it’s been over three weeks since we last had a really good, clear night sky.

What? Your statement: "during the dimming period, and could see the huge dust cloud". There is ZERO chance you could actually see the obscuring dust cloud. You could see the dimming, as pretty much anyone in the Northern Hemisphere could, even without a telescope, but to actually resolve Betelgeuse's disk beyond a single pixel, you would need telescopes that would take up as much space as a football field (using interferometry) and costs far beyond millions of Dollar.

So not going supernova. It is a nebula becoming a star and developing a photosphere.

It's Beetlejuice not battlejuice or whatever your saying.

The words said s NEUTRINOS would no penetrate our atmosphere. Must be written by a content specialist, non-scientist

Takes very high resolution photos…sees areas as small as 25 times the Earth’s diameter. 😅

This is high resolution? What a huge fish story. The distance claim and said observations from the claimed distance is scientifically impossible nonsense. Even the non visible light spectrum isn't going to be measurable from claimed distances. When was the last time you saw a burning furnace look like a laser point from even 1000s of miles away? {Even lasers spread out over distance} Stop lying about optical capabilities or expecting us to believe you can have burning balls of gasses in a vacuum and admit those lights are close.

Some of the graphics show the Moon and Earth very close to each other. Bad Science Art.
