Betelgeuse

[Weather-history]

Simulation of what a Betelgeuse supernova explosion might appear from the Earth

 

It would be amazing if Betelgeuse were to go supernova in our lifetime. Correction: If we see the explosion in our lifetime, if we see it in our lifetime, it would have exploded 650 or so years ago.

Last supernova observed within our galaxy was in 1604 famously observed by Johannes Kepler. The reminants of this is what we observed as the Crab Nebula today.

Please let it happen !  But I read it could be anytime between now and 100's of thousands of years ... hmmm.

When it does happen, it'll be cloudy.

I look at the simulation and am very thankful that it is over 600ly away rather than next door..

My understanding is that it probably has a while to go in terms of our view of time before going pop, a few 100,000 yrs,  but you never know?

This is the NY Times take on its recent and sudden dimming.  The story covers something that had not occurred to me, i.e that it is rather difficult to observe with large optical telescopes as it's brightness will damage sensitive optics, and, that there has been a request for amateurs with smaller telescopes to keep detailed records.

A familiar star in the constellation Orion has dimmed noticeably since October. Astronomers wonder if its explosive finale is imminent.

Still dimming, latest magnitude is just 1.5

The Great Dimming of Betelgeuse continues. According to astronomers, it's reached 1.5 magnitude. It's still dimming, but the dimming has slowed.

It would be interesting to see the constellaton now, when this anticylonic gloom shifts, it is normally the 11th brightest star in the night sky but it has dipped out of the top 25 at the moment. Orion would look a little odd.

The skies were clear here on the east side last night and Betelgeuse could be clearly seen but has dimmed, so much so that his 'belt' is now brighter than his left shoulder..

The latest magnitude for Betelgeuse that I have seen reported has it as 1.6

[Yarmy]

Yep 1.62

To be honest, looking at the above chart, it doesn't appear to be *that* unusual, but I'm going to keep following the above account.

If I ever discover a message from an alien civilisation, the first thing I'm going to do is send an urgent letter to the Red Cross.

 I saw orion the other night and it looked most strange indeed.

When you think about it, this dimming and those images of Betelgeuse occurred around 1378. Europe was recovering from the Black Death almost 30 years previous, England had a new king on the throne, Richard II,  Chaucer was around, there was a new Pope and an antipope and it may have been the year that the Sphinx lost its nose.
