Exploding Star Will Appear Like a Second Sun
The red giant Betelgeuse is on the verge of dying, as the star's extreme
size and luminosity suggest it will likely go supernova relatively soon.
In astronomical terms, that means it could explode anytime between one
and 1 million years from now. But whenever the big event actually
happens, it will be impossible to miss.
According to science and sci-fi blog io9, the star's explosion will be so
bright it will appear as if our planet has two suns for several weeks.
"For a few weeks, the supernova will be so bright that there will appear
to be two stars in the sky, and night will be indistinguishable from day
for much of that time," io9 explains. "So don't count on getting a lot of
sleep when Betelgeuse explodes, because the only sensible thing for the
world to do will be to throw a weeks-long global supernova party."
Located in the Orion constellation, Betelgeuse is approximately 640 light-
years from Earth and is one of the largest and brightest stars in our
section of the galaxy. Despite its size, the star is far enough away that
the explosion will have virtually no damaging effects on our planet —
it'll strictly be fireworks.

Correctly: B may have _already_ exploded, and the light might be on
its way here.
Betelgeuse is so big and close that it's the only star imaged as a
disk, not a bright point.
It has a ... lobe of brighter material sticking out of it. Toward us.

It makes Orion the easiest constellation to spot in the Northern
Hemisphere. Maybe they'll have to rename the Constellation "Lefty".
It won't be THAT bright, will it?
Depends on the time of the year. In early summer, the sun is between
earth and Orion. In early winter, they are on opposite sides of the sky.
There's still going to be enough radiant heat that it would have a
temporary, but unknown effect on global weather, and an unknown
electromagnetic storm.
Perhaps for novices, but anyone with navigation experience will more
easily spot Ursa Major (the big dipper).
640 light-years seems pretty close.
What about gamma rays?

Canyon stated the following: "Lochner claimed that direct
current transmission lines had inductive reactance"
LOchner blustered the following gibbererish "Yup, because
in the real world, DC transmission lines don't have
the perfect symmetry that you have to assume for your
overly simplified first-ordered differential equations..
Fact: there is no inductive reactance in direct current transmission line.
see below:
"DC transmission system on the other hand has more advantages over AC transmission system. DC system does not introduce a reactance in the line."
http://www.jcmiras.net/jcm/item/86/
Reactance
# When electricity flows down a cable, it generates an
electro-magnetic field. When the current changes, as it does with AC current, a counter electro-magnetic field is produced that acts as a resistance to the power being transmitted. These means that AC transmission of electricity loses power due to both resistance and to reactance. Because DC power transmission never changes direction, it is not susceptible to power loss as a result of reactance.

If there's not so much crash-course to go around, we could elect to
concentrate on the former. For posterity.

If B blows, it won't fade back to even its original magnitude within
our lifetimes. (The blow represents a transition from billion-year
fuel to million-year fuel...)
We might even get to watch the formation of a huge, brilliant Crab
Nebula.
I don't -think- they would be a big problem at the surface, although most
anything in orbit is liable to get fried.

Uh, there's a major gamma ray source only 9 light-minutes away, and we
seem to be doing okay.
Our atmosphere absorbs the them, which is one reason we don't see in
gamma rays.

I once tried to tell a colleague - otherwise technically literate -
that astronomers measured the exact weight of the supermassive black
hole at the center of our galaxy by timing the orbit of a star around
it.
He said, oh wow anyone living on a planet orbiting that star would get
sucked up into the black hole!
I'm like, uh, no, it's ORBITING the black hole, so the gravity exactly
matches the centripetal force. The inhabitants would feel no pull at
all.
He said, oh no here comes the black hole again! waaaugh! slorp

Sorry to hear you're still clinging to a false premise..
--And whining about Zepp's spanking you silly for your lies..
Big Bear is important to sailors since above about 30 North, it's ALWAYS
in the night sky. Orion obviously isn't.
But, since I -was- talking to novices, Steve can go stuff himself.
He's doubtlessly making a good living running a global warming deniar
site today.
But again, because of the scale of the event, even if Beetle Juice blew
today (or blew in 1461 ADE, I should say), that might take hundreds of
years to develop fully.

If Betelgeuse is pointing the 'wrong' way, it could dump a bunch of
gamma rays at earth.

Betelgeuse would be a type II--and at 640 LY, harmless to earth.

That is good.
In that case I hope it went nova about 639 years ago.
Hopefully nobody lived nearby, though.
Why did I think 9?
Maybe it happened right when they elected a noisy uneducatable talking-
head gun-nut to the presidency of their last, but fading, superpower.
Just as their ancients prophesied!
Yos, rugged individualism can handle a supernova, easily.
BTW how's the Heaven's Gate Club doing these days?
No, he was just like that. He knew I'm right; there was no reason to
acknowledge that. He was just having fun playing with the mythos of
black holes.
> Then it turns into one a them black hole doods that eats the whole

Cute, but I just remembered the (boring) correct technical response:
A black hole always weighs _less_ than the star which created it. The
rest of the star blows off.
So if we haven't fallen into Betelgeuse yet, then we are not going to
fall into its remnant. Which will probably be a pulsar or neutron star.
Nope that's not why... but nice try, Dummy...

Nope.. It's a little over eight minutes..

Nonsense. It will be bright, about as bright as a full moon, but to
claim it will be as bright as the sun is absurd. Besides, that would
be fatal to most life on Earth.

Ray Fischer | Mendacracy (n.) government by lying

At 650 light years it's not especially close. The brightest star in
the sky, Siruis, is only 6 light years away. It's big, but size
isn't what counts. Mass counts, and at 19 times the mass of the sun
it is big, but there are bigger stars. Really big stars have masses 40
times that of the Sun.
Another rightard elitist snob with pretentions of superiority.
hoo, boy. Next I'll be writing things like "It made the Aldeberon run in
less than 26 parsecs". I don't know what I was thinking.
Unfortunately, ones that big (and Betelgeuse falls into that category)
can produce what are called "hypernovae" which are events that have a bad
habit of sterilizing entire galaxies. The universe has one of those
roughly once a day, but since there are trillions of galaxies, the
chances of one occurring in the Milky Way are pretty low.

snickering at their imagined inferiority.

The original concept was that Betelgeuse was about to go
SN (supernova) and would light up the night skies from the
Orion constellation..

>
> Lazar's Element 115 .....

Terrific,
and I re-worked all the batch files for some other
feeds too. Here's what I've been reading of late.
"Out There"-remarkable yet kinda hurried, which matters
little to me. I find that book to be pretty credible,
though non-commital. Yes, it answers the question that's
been in everybody's mind for some time, unanswered by
any kind of authority (plural). So, great...there IS
some kind of coverup, but what's being covered up?
As I've said earlier, the Air Force and any others
engaged in the subject have not generated a single
reason or explanation to satisfy themselves to declassify
anything of importance. Perhaps the outer "arms" of
this galaxy, the Orion Arm being our district, are a
little more crowded than even Drake's Equation permits?
"Above Top Secret" hehehe, I can't keep from skipping
ahead to see some of the more recent sightings. Again,
we have the texts of MJ-12 and several plates of some
pleasent faces, and some of the international sightings
are really well done. It's not easy reading but it's
interesting to find parts about the nuts/bolts.
And that's what I really wrote to you about..
I've been making noises about the propulsion scenarios
involved with these sighting. Letting the sightings display
the overall characteristics of such a machine saves alot of
guesswork. The international sightings pointed it out,
at least to me, when one guy said that it sounded kinda like
a refrigerator taking off.
Later in the book, a guy that was present at some questionable crash
recovery
sight later on told his
daughter that the craft operate on water, and that it might
threaten the oil industry. To support this conjecture,
I believe that if I was pressed to do, I could find a significant number of
sightings around water, and I recall some from earlier publications of
observing hoses in the
water. If you think that boiling water under pressure
does marvelous energy transfers, try thinking about water
in a partial vacumn...or ammonia, or even methane.
So, in closing, I can see that my previous posting was
pretty useless, I'll try not to waste bandwidth again until
I've caught up my reading, but I thought that I might be able to add some
useful conjecture as to what kind of
"cover-up" might be occurring.
Thanks for the stats,
that was real big help.
