Most distant star ever seen….

[Stu]

Interesting articles here, I listened to a good piece on R4 about it this evening too, good guest speaker, didn’t catch her name.

Hubble: 'Single star' detected at record-breaking distance https://www.bbc.co.uk/news/science-environment-60931100

Tolkien fans will be pleased with the nickname, "Earendel" (/ Eärendil)

Will be great when JWST follows up with this. Amazing if it is truly a single star keeping in mind galaxies look like a small smudge at that distance in Hubble images.

Yes indeed. Very good timing with JWST coming online soon.

What an asset Hubble has proven to be, nearing the end of its operational life and it pulls off this, amazing.  It is certainly not going gently into that good night

Amazing isn’t it? Such an incredible instrument. Should be interesting to see it operating alongside JWST, perhaps they can complement each other in the years remaining for Hubble?

It really is Stu, absolutely breath-taking the way they keep getting this type of data from it.  Its pointing the way for the  young pretender .

What I want to know is - what's the apparent magnitude, and when does it go supernova?

Probably has already.

I find science discoveries like this so interesting, though I'm not going to lie. 99.7 % of it is way beyond me.

As we keep seeing deeper into the universe, and time, I get the feeling no matter how advanced we become, we just might never find the true end of it.

There will always be just a few more faint objects we can barely see.

Hubble will forever be one of the great names in exploration. 

Shame to know it is destined for the satellite graveyard.

Yes, true. I should have said "when will we see the supernova?"

I think the only answer can be ‘sometime between now and 12.9 billion years in the future!’

[Ags]

If the star is 50 solar masses, we won't have to wait more than a few million years at most... Grab your popcorn!

Easy for you to say!

For those of us whose Old English is a bit rusty (I hope the translation doesn't break the CoC!):

Ēala ēarendel,     engla beorhtast, ofer middangeard     monnum sended, ond sōðfæsta     sunnan lēoma, torht ofer tunglas,     þū tīda gehwane of sylfum þē     symle inlihtes! Swā þū, god of gode     gearo acenned, sunu sōþan fæder,     swegles in wuldre būtan anginne     ǣfre wǣre, swā þec nū for þearfum     þīn āgen geweorc bīdeð þurh byldo,     þæt þū þā beorhtan ūs sunnan onsende,     ond þē sylf cyme þæt ðū inlēohte     þā þe longe ǣr, þrosme beþeahte     ond in þeostrum hēr, sǣton sinneahtes;     synnum bifealdne deorc dēaþes sceadu     drēogan sceoldan. Nū wē hyhtfulle     hǣlo gelyfað þurh þæt word godes     weorodum brungen, þe on frymðe wæs     fæder ælmihtigum efenece mid god,     ond nū eft gewearð flæsc firena lēas,     þæt sēo fǣmne gebær geomrum to gēoce.     God wæs mid ūs gesewen būtan synnum;     somod eardedon mihtig meotudes bearn     ond se monnes sunu geþwǣre on þēode.     Wē þæs þonc magon secgan sigedryhtne     symle bi gewyrhtum, þæs þe he hine sylfne ūs     sendan wolde.[9]

Hail Earendel, brightest of angels, Sent to men over middle-earth, And true radiance of the sun, Fine beyond stars, you always illuminate, From your self, every season! As you, God born wholly of God, Son of the true Father, were ever In the glory of heaven without beginning, So now your own creation awaits you Through eternity in need, that you send To us that bright sun, and you yourself come So that you illuminate those who for the longest time, Covered by smoke, and in darkness here, Dwelled in continual night; enfolded in sins, They had to endure the dark shadow of death. Now we believe in joyful salvation, Brought to people through the word of God, Which in the beginning was from the Father almighty, Jointly eternal with God, and now again became The flesh without sin that the virgin bore Through suffering to safety. God was with us, Seen among sins; the mighty child of fate And the son of man dwelt together, United amidst the people. We may express Our thanks to the Lord of victory always through our deeds, Because he wanted to send himself to us.

(The Christ of Cynewulf)

Some of Tolkien's earliest writing was inspired by it:

I love the fact that gravitational lensing was a theory then observed and has become a tool to be used like this. Similar to the images published of black holes you just wouldnt have believed it possible some years back.

If it's the same piece that MrsG heard, it would have been Megan Argo who teaches at UC Lancaster.

A great speaker, if you get a chance to catch her at a local astronomy society it's well worth going along.

We were fortunate to be able to get a Zoom talk from her at our Astro Society last May.

Thank you! Yes, that was her. She was very good I thought. She clearly knew her stuff, but made it very easy to understand.
