“ Supergiant star Betelgeuse has been getting dimmer at an unprecedented pace over the past few months, leading some astronomers to wonder if it might be in the process of the collapse that precedes a supernova explosion. But there are other possible explanations, and we should have a better idea of what's happening to the massive star by the end of the month.

Veteran Villanova University astronomer Edward Guinan has been watching Betelgeuse for decades and reported earlier this month that the star appears to be "the least luminous and coolest yet measured from our 25 years of photometry."

How many years ago did this happen? Meaning, how far away?

It's relatively close to Earth, only 642.5 light years away. What astronomers are seeing today actually occurred back in 1378.

I managed to find a source which said 700 years, I think. The 11th brightest star in our skies.


I was thinking that the numbers were just a variant - but we cannot be shifting our distances by 60 light years on a regular basis. Don't know the reason for discrepancy.

I don't know the reason for the vast discrepancy in distance. As close as 427 Lty to 700 lty. That's quite a gap.

The massive dip in brightness is almost certainly a notable curiosity, and not any portend to an immediate ( from our perspective ) onset of any super nova. It is, however, a bit of info that future astronomers hopefully will be able to access when it finally does explode. Perhaps 100's or 1000's of years from now.

That is a big discrepancy. At this moment, I don't even recall how we measure distance in astronomy. Maybe somebody's Slide Rule needs calibration.

642.5 light years seems to be the most accepted number I'm seeing.

I agree.

I'm wondering why the search engine results came up with 700, which is not even rounded from the 642 figure.
And 427 is even further out of range.

Do you know why there is such discrepancy?

I know that a star's distance from Earth never changes. A star's magnitude (brightness) can fluctuate slightly depending on certain conditions.

Best I can figure is that some who write these things are lazy as fuck and don't have a curious cell in their brains.

Most folks don't GET the whole solar system is in a galaxy and there are billions of galaxies. Like the 1 mile wide asteroid which passed by Earth today. It was 15x the distance from the Earth to the moon. Zero shot at hitting us, this time. Yet we got videos of meteorites hitting the Earth, the extinction of the dinosaurs, etc... and for what?

Update - So B was at 35% of observed brightness, but now has been steadily increasing to 43%.

Short and simple, no imminent super nova.

Dammit.

Still, interesting to watch a red giant go through its old age changes. Even if we're not gonna witness anything truly spectacular from it.

As you were.

Yes, interesting. And thanks for the head's up. If it had expired, folk would be whining that nobody told them beforehand.

So, ummmm....

Does this mean you were looking in the wrong direction when the big explosion happened?

Too cool!

Seems no one saw this explosion. We KNOW about it from x-rays, and the Chandra observatory.

Honestly, I don't know enough about black hole explosions to comment, other than this one happened 390 MILLION light years away, and Betelgeuse is only 640 light years away.

I had noticed anther story about Black Holes eating galaxies, from the end of last month - but I didn't link it.

You think there will be video coming out of this explosion? The view must have lasted more than a few seconds - or not? maybe slow motion replay could work.

I guess this one made a void big enough to fit 13 Galaxies within.

Is it too late to blame Space Force?





With the variant output of B, I had considered if something was getting in the way. But I conjured that an orbiting body would have too quick a duration of eclipse.
But what if there is a black hole, or invisible explosion in between B and us? The light could be sucked away to the side, and the black hole could be unstable, causing variations.

Still only @ 43% of normal brightness.

Feelin' pretty dim myself.

Speaking of Beetlejuice...

They rebooted it. The 2020 update takes place in Chicago.
