Who's "we"?
My Situation? Er..what do you want to know? I'll tell you EVERYTHING.
Dark in what way?
I'm here to help.
What I am noticing is you don't seem fully engaged in this thread. 🙂
I am reasonably interested in Physics and Mathematics, since we live in a golden Age for discoveries. Huge reading list which i delve into for several hours each day.
This distant lensed Star seems a major discovery. Time has already been allotted for James Webb to have a look too.
I presume a spectral analysis will be done, which should reveal it to be lacking the heavy elements if Big Bang Theory is right.

Low metalicity - expect hydrogen, helium, lithium etc. here is a stellar nucleosynthesis periodic table. The closer the the BB, the fewer heavy elements as Steve notes
The star has been given the Tolkienesque name of Earendel - from an Old English word meaning 'rising light' or 'morning star'.
In J.R.R. Tolkiens's mythology, Eärendil was a Half-elven mariner who carried a star across the sky at the end of the First Age.

I can assure you my good friend while I'm perusing this particular thread that you have my undivided attention as do all other contributors. However due to my lack of knowledge in such matters I must defer to those such as yourself to guide and inform me of the meatier matters of this topic. However interest is keen and I wish for a long and happy interaction. I'll have you know the star to which you refer came to my attention before it appeared in this thread as I have a very clever browser informing me of all things new and old as soon as I flip the lid...uncanny! And further more good sir, my vastly open mind compels me to contemplate and consider the merit in the statements presented, some as factual when quite often they are merely conjecture. However rest assured I have the uncanny ability to decipher which box I should put them in for further examination. For example, spectral analysis makes perfect sense in reference to the question at hand. Therefore into the box o' fact it goes..maybe.🤔
What I try to avoid (not always successfully) is negative engagement.
Thoughts and behaviours that are unfavourable to the work of scientists can have little positive effect in our quest to understand the universe.
I read that, given the age of the universe it resides in, Earendel is not likely to be one of the first stars.
However, based on its brightness, it is estimated to have a mass equivalent of tens or even hundreds of solar masses.
This would indicate that is an early fuser of new heavy elements.
JWST images and spectra will improve estimates of the star’s mass, temperature, and spectral type, revealing its true nature.
yes - probably a stellar progeny of many previous stars already at that stage (900 million yrs ATBB). Some of the early stars were absolute monsters.
TBH, I was scratching my head over "Earendel". 😳
I am hard-pressed to relate that to "Anglo-Saxon".
I know that AS for Star is "Sterre". Or perhaps "Tungol".
Can anyone explain? I am lost. Is it Hobbitish?

Theoretical models predict that the first stars had masses between 100 and 1,000 solar masses and consequently would have had relatively short lifetimes in the order of only a few million years - before exploding as supernovae.
They would have had surface temperatures about 17 times higher than the Sun’s, meaning that the first starlight in the universe would have been mainly ultraviolet radiation.
This UV light from the first stars was responsible for reionising the surrounding neutral hydrogen gas, a process which ultimately led to the formation of galaxies.
Webb will be able to see back to the first stars, and the first galaxies that formed after the hydrogen reionisation process.

No one actually said that Earendel was "Anglo-Saxon"!
There is an Éarendel in Germanic mythology - a hero God.
The name Éarendel was a tremendous inspiration to JRR Tolkien who concocted an utterly fictitious hero-myth around it - that of Eärendil.
P.S. I watched the film "Tolkien" last night - not my best cinematic experience!

I hate when somebody use mythology to name discoveries . Conservatives and religious groups use this against science like "see we knew the existence of this something before your science can find it out " . it give a very wrong message especially to the young audiences . For example venus Saturn pluto. I myself though they were discovered by some relegious saints or something or were written and told us by some holybook of pure facts . In short destroying scientific temperament
The use of mythology does not appear to have been the case in naming Earendel.
I clearly stated earlier that the name of the star came "from an Old English word meaning 'rising light' or 'morning star'."
It would appear that I should never have mentioned Tolkien! 🙄
I tried an Old English to Modern English translator.
Earendel translated as dayspring; dawn; a shining light; ray; ray of light.
Apparently, Old English is a 'moderately inflected' language similar to modern Icelandic or German.
An 'inflected language' is a language that changes the form or ending of some words when the way in which they are used in sentences changes.
Apparently, this makes Old English difficult to translate.

Learning all the time! 😎

Interesting, Betelgeuse had a bass that is 10~15x the sun’s and has a diameter of > billion miles. A star 100-1000 times the suns mass would be absolutely enormous. All these early stars would have been super nova’s with a residual black hole after expiring.
JWT will open a new window on the early universe. Exciting stuff ahead!
