Betelguese getting some attention for dimming
Discussion
Apparently doing what it normally does and dimming, noticeably at the moment according to some with the Mrk 1. I understand the window to see it go super nova is in the region of 100,000 years give or take a year or two.
One can hope I get to see it in my lifetime. But it is known as a variable star but with the recent weeks of cloud, hardly a clear view of it myself. Dipped lower in the late 70's to mid 80's. Chuck in the star name and pick the elements you want.

ALMA took a picture of it. Nice bump.

Size compared to our local star.

A tad up from Orions belt btw.

Yes, Betleguese has great potential to put on a great display if and when it self destructs.
It's 700 light years away from earth - so in reality, it could have gone bang at any time within the last few centuries but the light of the explosion hasn't reached us yet.
If anybody wants to look at it, here's where you will find it. Orion is now at its best for viewing.

On my list of to do. More of these courses that is, might have a cack at this one. Keep finding myself hitting other things to do when I think I have spare time. Missed this one in my in tray (signed up to future learn emails and never read them).Let you know when I finish the course......
My limited understanding and I expect to be corrected. From what I have read, one expectation is it could be the brightest object in the sky (apart from the Sun) for months. And possibly visible in the day if it is above your horizon. But nothing dangerous as we are too far away and magnetic field.
I understand that some types of stars are very dangerous, Wolf Rayet is one type and there was a worry over one that seemed to be aimed at us but we are now deemed safe from that one (game ray burst).

What I can gather with certain stars, when they go, the gamma ray burst beams out from the poles. WR104 was considered a risk to life on Earth (??) before they reviewed the info. it is over 7,000 light years away. We are a few degrees it seems from looking right down the bottle after some research done by Australian astronomer some 10 years ago.
Really should be getting some more courses in now I have the time.

Cwar that'd be a good one to see in my lifetime!
Rather like adults should talk at just beyond the vocabulary of children to bring them along, I've been watching PBS Spacetime [Youtube] for a few years, excellent mix of subjects broadly encompassing 'the universe' which goes from the planck scale to the universal and everything relativistic in between - it's fascinating to me how to understand the incomprehensibly large you have to also understand the confoundingly small, and the guys do a great job of keeping it interesting and tantalisingly almost-out-of-reach complex at the same time. Highly rec'd.

Out of interest whats the science for 100 000 years estimate?One can hope I get to see it in my lifetime.
