Astronomers think they have detected the most distant star ever
The uncertainty of science: Using the Hubble Space Telescope astronomers now think they have detected the most distant single star ever located, the light of which is estimated to have come from a time only less than a billion years after the Big Bang itself.
The star, nicknamed Earendel by astronomers, emitted its light within the universe’s first billion years. It’s a significant leap beyond Hubble’s previous distance record, in 2018, when it detected a star at around 4 billion years after the big bang. Hubble got a boost by looking through space warped by the mass of the huge galaxy cluster WHL0137-08, an effect called gravitational lensing. Earendel was aligned on or very near a ripple in the fabric of space created by the cluster’s mass, which magnified its light enough to be detected by Hubble.
The arrow in the image, cropped and reduced to post here, points to the theorized star. Note the arc that tiny dot lies along. This arc is the result of the gravitational lensing, and illustrates quite bluntly the large uncertainties of this discovery. We are not seeing the star itself, but the distorted light after it passed through the strong gravitational field of the cluster of galaxies. The scientists conclusion that this dot is thus a single star, must be view with great skepticism.
Nonetheless, the data is intriguing, and will certainly be one of the early targets of the James Webb Space Telescope, which could confirm or disprove this hypothesis.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in the past two weeks has the mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuses to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

Gravitational Lensing. Love it.
Ripple in the Fabric of Space. Love it.
Detecting a star at “a time only less than a billion years after the Big Bang itself.”
Silly light.
Albert we need you now more than ever.
Come on Jim W. , we are awaiting your “cool images”.
I’ll drop this in here…..

“How Far Away Is It: The Cosmos”
[Chapter 16]

40:36
Eärendil was a mariner
that tarried in Arvernien;
he built a boat of timber felled
in Nimbrethil to journey in;
her sails he wove of silver fair,
of silver were her lanterns made,
her prow was fashioned like a swan,
and light upon her banners laid.
In panoply of ancient kings,
in chainéd rings he armoured him;
his shining shield was scored with runes
to ward all wounds and harm from him;
his bow was made of dragon-horn,
his arrows shorn of ebony;
of silver was his habergeon,
his scabbard of chalcedony;
his sword of steel was valiant,
of adamant his helmet tall,
an eagle-plume upon his crest,
upon his breast an emerald.
Beneath the Moon and under star
he wandered far from northern strands,
bewildered on enchanted ways
beyond the days of mortal lands.
From gnashing of the Narrow Ice
where shadow lies on frozen hills,
from nether heats and burning waste
he turned in haste, and roving still
on starless waters far astray
at last he came to Night of Naught,
and passed, and never sight he saw
of shining shore nor light he sought.
The winds of wrath came driving him,
and blindly in the foam he fled
from west to east and errandless,
unheralded he homeward sped.
There flying Elwing came to him,
and flame was in the darkness lit;
more bright than light of diamond
the fire upon her carcanet.
The Silmaril she bound on him
and crowned him with the living light
and dauntless then with burning brow
he turned his prow; and in the night
from Otherworld beyond the Sea
there strong and free a storm arose,
a wind of power in Tarmenel;
by paths that seldom mortal goes
his boat it bore with biting breath
as might of death across the grey
and long forsaken seas distressed;
from east to west he passed away.
Through Evernight he back was borne
on black and roaring waves that ran
o’er leagues unlit and foundered shores
that drowned before the Days began,
until he heard on strands of pearl
where ends the world the music long,
where ever-foaming billows roll
the yellow gold and jewels wan.
He saw the Mountain silent rise
where twilight lies upon the knees
of Valinor, and Eldamar
beheld afar beyond the seas.
A wanderer escaped from night
to haven white he came at last,
to Elvenhome the green and fair
where keen the air, where pale as glass
beneath the Hill of Ilmarin
a-glimmer in a valley sheer
the lamplit towers of Tirion
are mirrored on the Shadowmere.
He tarried there from errantry,
and melodies they taught to him,
and sages old him marvels told,
and harps of gold they brought to him.
They clothed him then in elven-white,
and seven lights before him sent,
as through the Calacirian
to hidden land forlorn he went.
He came unto the timeless halls
where shining fall the countless years,
and endless reigns the Elder King
in Ilmarin on Mountain sheer;
and words unheard were spoken then
of folk of Men and Elven-kin,
beyond the world were visions showed
forbid to those that dwell therein.
A ship then new they built for him
of mithril and of elven-glass
with shining prow; no shaven oar
nor sail she bore on silver mast:
the Silmaril as lantern light
and banner bright with living flame
to gleam thereon by Elbereth
herself was set, who thither came
and wings immortal made for him,
and laid on him undying doom,
to sail the shoreless skies and come
behind the Sun and light of Moon.
From Evereven’s lofty hills
where softly silver fountains fall
his wings him bore, a wandering light,
beyond the mighty Mountain Wall.
From World’s End there he turned away,
and yearned again to find afar
his home through shadows journeying,
and burning as an island star
on high above the mists he came,
a distant flame before the Sun,
a wonder ere the waking dawn
where grey the Norland waters run.
And over Middle-earth he passed
and heard at last the weeping sore
of women and of elven-maids
in Elder Days, in years of yore.
But on him mighty doom was laid,
till Moon should fade, an orbéd star
to pass, and tarry never more
on Hither Shores where Mortals are;
for ever still a herald on
an errand that should never rest
to bear his shining lamp afar,
the Flammifer of Westernesse.
I am getting very confused about this sort of thing.
Supposedly we exist in an expanding universe. That was what the “Big Bang” was supposed to have started.
Yet we keep seeing light from stars, where the position of the star, “only a billion years after The Big Bang” is billions of light years away from where the Big Bang happened.
That start isn’t in that position NOW. It WAS in that position. ( if the Big Bang happened 13.8 billion years ago), 12.8 Billion Years ago.
https://en.wikipedia.org/wiki/Big_Bang
So how long will a star actually live? https://socratic.org/questions/what-is-the-average-lifespan-of-a-star, says that our Sun should have a life expectancy of 10 billion years.
So there is a really good chance that Hubble caught picture of something that existed 12.8 billion years ago, and DIED 2 billion years ago in a place far far removed from where we see it today.
What gets me is that it was WHERE it was, when the Universe was only 1 billion years old. So how fast was the Universe expanding in that first billion years? Or, are we looking at a point very very CLOSE to the epicenter of The Big Bang? In which case how did EARTH and our Sun get so far away.
Now I am aware that the expansion of the Universe is not supposed to have anything to with anything physically “moving” anywhere. It is supposed to be a function of the volume of “Space Time” actually increasing. Still all this stuff about seeing stars further and further away is hugely confusing to me.
What happens if we “see” a star whose distance can be established as further away than say 15 billion light years. That would upset the apple cart completely.
