                 Superstar Eta Carinae Outshines the Sun 5 Million Times

                  A Cosmic Ray Gun Duel Reaching Across the Milky Way

 

 

I have proposed that Eta Carina is the

Seventh Angel of the Book of Revelation.

 

That is why I consider updated news of

Eta Carina important for you to see.

A dramatic drop in Eta Carinae's stellar winds

could herald a bright future.

After a huge outburst of gas that occurred more than 150 years ago,

it has largely been hidden by a dense cloud of dust —

a strong indicator of sporadic eruptions.

 

 


 

 

 

WHY HAVE THE STELLAR WINDS DROPPED?

 

Now, Eta Carina, which sits in our part of the Milky Way

some 2,300 parsecs (7,500 light years) from the Sun,

is puzzling researchers and theorists all over again.

 

 A US-based team has recorded a steep,

inexplicable drop in its stellar wind —

the outflow of gas from the star —

measured as a change

in the emission lines, or lines in the spectrum caused by

the emission of light at particular wavelengths.

 

 


 

 

 

 

UNIVERSITY OF MINNESOTA RESEARCHERS

Researchers from the

University of Minnesota in Minneapolis

recorded the dip from the eruptive,

luminous variable star using data

from the Gemini South Telescope in Chile

and the Hubble Space Telescope.

 

Their results are detailed in a paper accepted for publication

 in Astrophysical Journal Letters1.

 

"The collapse in the emission lines seemed almost too rapid

and drastic to believe,"

Image result for astronomer kris davidson

says Kris Davidson,

an astrophysicist at the

University of Minnesota and a co-author of the latest study.

 

In January, Davidson's

colleague and the study's lead author

Andrea Mehner

first noticed the effect in data from

the Gemini South Telescope.

 

The team then confirmed Mehner's findings through

observations using Hubble.

Their findings have been independently verified by astronomers

affiliated with

Stony Brook University in New York and

the Georgia Institute of Technology in Atlanta.

 

"Eta Carina is more than a variable star," says Davidson,

"it's just nuts."

 

 


 

 

 

SUPERNOVA IMPOSTER

 

The root of Eta Carina's oddness lies in

the supernova-like eruption

event that began in the late 1830s and lasted

for some 20 years.

Two sets of blended spectral lines in the spectrum of Eta Carinae, seen with the Hubble Space Teleescope a decade apart. Relative to the underlying continuous emission, the lines have collapsed to only 1/3 of their original strength.

 

Lines in the emission spectrum of Eta Carinae

have collapsed to

only a third of their original strength in a decade.

UNIVERSITY OF CALIFORNIA BERKELEY

Nathan Smith,

a postdoctoral researcher in astronomy at

the University of California, Berkeley,

who was not involved with

the observations, says that

 

Eta Carina is a "key object for understanding the

instability of the most massive stars".

 

Smith adds that these eruptions may provide glimpses of what

to expect from the Universe's first stars,

called population III stars.

 

Meanwhile, if Eta Car's current trend of decreasing winds

continues, in a decade it will have very nearly emerged

from its cocoon of dense gaseous outflow.

 

That would return it to the state observed by Halley some

300 years ago, when it was seen as a hot, blue star,

now known to have been of spectral class O.

 

 

The Minnesota team notes that this would

finally enable contemporary

observations of the radius and surface

temperature of Eta Car,

which is estimated to have the mass of

well over 100 Suns.

STRANGE LIGHT IN THE SKY

I wanted to go over with you

a  strange discovery so we can

keep our eye on developments and be aware t

hat something is going on.

 

Of course we are anticipating the arrival  of the light from

the center eye of Supernova 1987a.

 

Now look at this. 

 

A star named Eta Carinae that has dimmed for decades is

now tripling its energy mostly in invisible light.

 

Note, What puzzles astronomers is that Eta Carinae

was not supposed to do this.

 

This statement is from

Image result for astronomer kris davidson

 

Kris Davidson,

astrophysicist

from the University of Minnesota.

 

"Occasionally something happens in astronomy

hat is so bewildering

that it makes astronomers nervous.

This is weird, we don't understand."

 

Here is something weird tripling its energy in invisible light

and this is what  the news release from CNN says.

 

  "The star about 7500 light years from earth

is among the most

massive and energetic in the known universe.

 

The energy it emits, most of it invisible radiation is up to

5 times more powerful then the sun."

 

Now look at this

 

Eta Carinae was a routine part of the sky

in the Southern Hemisphere

until the 1840’s when it was observed to erupt

with a massive outflow of energy.

 

For awed watchers on Earth it was as if a light bulb in the

heavens was suddenly turned on.

 

 

It became very very bright for 20 years .

 

 Its brilliance matched a Supernova and then it became

dimmer and dimmer until it faded from view.

 

Astronomers learned that it had been

blocked by an immense

cloud of dust so they theorized that it

 would become visible again

as the dust cleared.

 

Astronomers expected the star to slowly brighten until

sometime in the next century.

 

  But Eta Carinae surprised the experts.

 

Over a matter of months the star was seen spewing out vast

amounts of energy in all bands of the electromagnetic spectrum.

 

Astronomers had not expected such an energy burst for

many decades and it was expected that the star would first emit

cooler radiation sort of as a warning of coming violence.

 

That did not happen.

Consider This From Astrophysicist Kris Davidson

 

There are about 6000 stars in the sky visible to the naked eye.

 

We understand them all with the sole exception of

Eta Carinae.

There is no theoretical explanation for it.

 

Theorists believe it may create a hypernova a stellar explosion

many times more powerful then a supernova.

 

 It could then start spewing gamma radiation in short waves

that might equal the entire energy of the sun.

 

Such bursts might even be hazardous at 7500 light years,

the distance to Earth

 

 

So the Sky King is obviously placing things in position.

 

As I have tried to share with anyone that would listen,

strange and powerful things are coming down upon the earth

that will totally change the structure of civilization as you know it.

 

I am providing this documentation of what is about to happen even

though the scientists who are watching really do not know when or how.

 

The word ETA means 7th.

 

The word Carinae means keel as a ship or the breast of a bird

MYSTERIOUS ERUPTIONS

Huge stars like Eta Car can erupt for reasons that Davidson

says are about 95% "mysterious".

 

One theory is that once these massive stars near the end of their short lives —

after some 2 million to 3 million years —

perturbations in their cores may set off sporadic

'supernova impostor' eruptions.

 

Eta Carina, which is five million times more luminous than

the Sun, was the first such impostor detected,

although about a dozen are known to astronomers today.

 

During its mid-nineteenth-century eruption,

Eta Carina lost about ten times the mass of the Sun.

 

Although this loss was equivalent to only 10% of its mass,

the star's outer 50% was ejected.

 

As a result, the star has still not returned to thermal

and rotational equilibrium.

Since 1858, it has been observed only as a massive gaseous outflow,

losing the equivalent of one Jupiter-mass in gas per year.


HIDDEN BEHIND THE ANGELS WINGS

 

"We still can't see the star itself," says Davidson,

"but only an opaque dense wind outflow surrounded by muck —

really bright ejecta."

Before 1700, Davidson notes that Eta Carina was a fourth-magnitude star,

recorded by astronomer Edmond Halley and only a few others.

By 1843, it was almost as bright as Sirius before suddenly fading in 1858.

 

"After a supernova impostor explosion," says Davidson,

"the star is in a state [of disequilibrium] that none

of the theorists' computer codes are set up to deal with."
