A Serendipitous Star (and most distant star) - Sixty Symbols 

First Light by Dr Chapman (Amazon link): amzn.to/41RH7Ec The University of Nottingham physics and astronomy: bit.ly/NottsPhysics Deep Sky Videos: ru-vid.com

Dr Emma is awesome. Would love to see her more often on Sixty Symbols!

The star was nicknamed Earendel by the discoverers, derived from the Old English name for 'morning star' or 'rising light'.[1][10] Eärendil is also the name of a half-elven character in one of J. R. R. Tolkien's books, The Silmarillion, who travelled through the sky with a radiant jewel that appeared as bright as a star. NASA astronomer Michelle Thaller confirmed that the reference to Tolkien was intentional.

When she said "That's the pain of astronomy" I felt it.

About anthropomorphizing stars, i think every field does this. I'm a physicist, and it makes it much easier to discuss some things if you ascribe a will to, for instance, electrons.

For anyone wondering, the average speed of an ̶a̶i̶r̶ ̶l̶a̶d̶e̶n̶ ̶s̶w̶a̶l̶l̶o̶w̶ cruising speed passenger plane is 575-600 mph

Amazing. What a wonderful, fun study ! Great chat, Sixty Symbols does it again !

JWST is killing it!

So much passion and joy in and for stars! Wonderful!

3:00 1. the international units is km/h and 2. it's around 950km/h

Great interview

1st here for astro-nerding, stayed for the Dr. ❤Wow❤ Stunningly brilliant, some star!

Dr Emma has a captivating energy, would love to see her more often.

Dr Chapman is so cool!

Super-interesting stuff from Emma and Brady

This is great

came for Tolkien lore, stayed for science

12:30 My thoughts exactly on astronomical naming conventions

Spaceporn Cornwall? Awesome!

Fascinating / cool.

The problem with Earth emissions being lensed by the Sun is that as we orbit, it sweeps around a massive circle over the year, so if you are far enough for it to matter, you simply can't go fast enough to get a stable signal. I mean, a problem from the point of detecting it, I just remember the storyline of Sagan's Contact, perhaps it's not at all a problem... As unlikely as it is, if someone ever catches any of it, it'll be nothing more but a short blip, something like their version of our "Wow!" signal.

The most distant, observable star that JWST can see...

Realy I like this video so much its so interestyng

"Humans are.. you know.. nothing and insignificant" Lovely!!

The Light of Earendil

Eärandil was a mariner…

Isn't it "going to stat put" since at these distances things become time dilated so even if it was moving we will never be able to see it, since it's kind of frozen in time. General Relativity being as it is.

Earendel is 28 billion light years away (comoving distance). I feel like it's confusing to call it 13 billion light years and not explain the difference, since you end up with different sources quoting different figures.

For some reason, I never cottoned on to the fact that the first stars haven't been observed.

Astronomy goes into size, distance, composition etc etc etc of stars, planets, Moons, galaxies of course. I'm more interested in Cosmology. Origins, background radiation, the universe! etc.

exciting researcher, book ordered!!

Given the size and scale of the universe, isn’t it possible (or even inevitable) that every star gets lensed like this somewhere, sometime?

A haunting end there...

How was it determined to be a single star rather than a star cluster?

3 things 1. Awesome first question! I feel even Earths 6 month movement would cause some visual changes at such magnification. 2. Never explained HOW we know it's a single star. Spectrography I presume, but a comparison of a star vs a galaxy's spectrum would've been great. 3. What's up with the video segment names?? 🤔

I can't wait until JWST or future Extremely Large Telescopes show us the first image or spectral data from a Population 3 star, but especially a quasistar. 🤓 That will be some very ancient light, but it's out there! Observing a quasistar will definitely solve the Supermassive Black Hole genesis problem and I believe 100% in the hypothesis. It is the best model to describe the extremely rapid formation of SMBHs and Ultra Massive Black Holes like TON 618 which couldn't have formed via mergers alone.

And that star has probably long ago burnt out and is no more yet we can still see its light headed towards us due to how long it takes to get here. EDIT: oh you mentioned it later in the video.

Sometimes an outsider question can being new insight...2:01

Is it further than Bradford?

Keep on looking

✨✨

Propeller planes are about 300 mi/hr. Jets are about 2-3x faster. Rockets are about 50x faster.

I highly recommend people to watch the movie Sunshine 2007!

What I find hard to understand is that near Earendel there are a gazillion red spots, two or one pixels large representing complete galaxy's...

If Toyah had gone into astronomy rather than music.

Is it possible that light from the sun or radio from earth bends around multiple stars or galaxies and can make a 180 degree turn? If yes, could we see our own past? Here's another crazy idea, could we create a cluster of small satellites, put them at Jupiter's L1 point, use the sun as a gravitational lens, and the cluster of satellites as a computational lens/moire lens to reach/see the furthest stars? Just thinking outside the box.

Indeed, if intelligent life (in our current focal of time) was watching us via a solar lensing, they would probably watching Galaxy Quest. ;O)-

Gravitational lensing of our signals via the Sun by aliens is one of the plot points of The Three Body Problem novels.

Could gamma rays be magnified and concentrated towards us and pose a threat? Sounds like a death star 😂

I've got an astrophysical (xenopological) question: wouldn't the region around Sagittarius A* naturally be the premier location in the galaxy for spacefaring interstellar species to congregate? Decelerating to arrive there naturally would require massive energy, but still, it seems like every alien race would treat it as a rally point.

Lensing Earth using our Sun: How far away from Earth is the focal point?

Vingilot!

I feel sorry for all the airliner captains who provide muffled airspeed to passangers and obviously not even the phds with curious brains are paying attention.

13 billion lightyears.... Holy Mother of God...

I really hope this was named as a LOTR reference.

Ooh, who’s the new presenter?

Would it be at all interesting to take these smeared images and transforming them into the how the original looked?

🌟 ⏳️ 🔭

Gotta love that name. Conjures images of an Elf-man with a bright glowing gem, sailing through the loneliness of space 😁

isnt it a galaxy not star isnt a single star too faint to be detected

Sun is not that big, SGL will start to focus at about 550 AU, so not that far away. And they'll have a lot of deconvolution to do :)

por que não configurou o idioma e permitiu legendas? pfff

"Euclid's Cat"..Here are the basics for the speed of light colors..B & W Are E.P.R. Same Line Instant..Universe Started Black "Lost Time"....There is no green or orange..Only Yellow on top of blue...Or Yellow on top of red..Euclid compared to Schrodinger's Cat...Postulate 5 = Blue = Future Uncertainty.."Universe Start"..."Lost Time"...Postulate 1 "Green Door In"...Postulate 2 "YELLOW"...It is On TOP..Joining 1 + 3 Together....Postulate 3 "Orange Door Out".....Postulate 4 Red = Past Certainty...."Completeness Of The Time Tick In The Classical World We Know"....Purple = Infinity..Take Care...Bye....

The problem with the idea of some other distant civilization using our sun as a gravitational lens to pick up signals from Earth is that, due to our orbit around the sun, they'd only be able to pick up a signal from Earth one day of the year. It's much more interesting (for me) to think about using other, more distant but larger stars in our own galaxy for lensing, since the relative position of solar systems behind it wouldn't be moving on nearly the same timescales.

Actually, an "observation" fact here is a bit more ojected than proven...

She is funny.. i like her.. 👍

Hey sixty symbols, what are we missing out from Maxwell's need to annotate with quaternions? Did we lose signal through Heaviside's compression of the equations. Did Maxwell not have access to Heaviside's method, or did he choose quaternions because of some kind of esoteric sense he, Maxwell, was trying to convey?

Thumbs up because of "I could open the tomb of spacetime "

Thank you. Two things I learned from this video 1) Humans and human life span is insignificant 2) scientists should start experiments by throwing dust and metals in fusion reactor instead of using pure deuterium and tritium plasma...may be electron cloud repulsion of dust brings two nucleus closer faster ( because almost all starts in our galaxy has metals in them)

'Earendil' a name derived from Tolkien. Elrond's father

:)

Wow, look at that wall.

its amazing that by lucky chance the universe offers a lense with a diameter and focal lenght of several million lightyears. and this isnt even the perfect case of a circle, its just a smeared arc. there have to be some insanely perfect examples at some locations in the universe

Dude over-uses "preshoooomably". Every second sentence. Does my head in.

Female George Russell?

Humans are insignificant?

The speed of light is not constant since the measures of time and distance are not constant. The changes in time and distance because of gravity compound the changes in the speed of light. Objects in space are also not as far away as they seem to be because of the expanded distance from the diminished gravity between gravitational forces.

Had to watch this one on mute with the captions on. The vocal fry is unbearable.

I would love to see an extensive survey done of gravitationally lensed distant galaxies.

Taken with a grain of salt, almost anything can be accepted.

There is so much wrong in astrophysics and cosmology. It’s almost entirely based on assumptions, assumptions of dark matter assumptions of dark energy assumptions of a universe expanding from nothing into oblivion for no reason assumptions of a single age of the universe and the assumption that everything just appeared from nothing like magic. Redshift is from the accumulation of gravity between us and distant galaxies. It’s from a light source from a greater mass and passing through areas of mass and gravity causing redshift. Distant galaxies are more redshifted because of the greater amount of mass that the light has to pass by. The vacuum energy is from black holes absorbing space time, not from imaginary inflatons. Dark energy is assumed because the correct differing measures of distance and time that also compound the change in lightspeed are not being taken into account. Vacuum is the opposite of inflation. Matter and energy cannot make or direct themselves and they are only going from order to disorder disproving the idea that they made and directed themselves. The problem is that cosmologists are not considering the actual evidence in front of them. The evidence is one giant elephant 🐘 in the room that the (secular) scientists try their hardest to ignore and pretend that the elephant 🐘 isn’t there when the elephant 🐘 of actual physics is there. The speed of light is NOT constant because the measurements of time and distance are NOT constant throughout the universe. The light from distant galaxies only slows down when it encounters the mass inside of a galaxy according to general relativity which is an observed fact. There’s no excuse for scientists to be making up their own version of physics.

I'd love to know how she comes up with all of this by 9 little pixels of faded blurry light. It sure feels like bigfoot footage to me. It's funny how we get all the story telling about it, but no science behind the claims. She's not here to teach us how she knows these things... just trust me bro" vibes. How do we know it's a star at all and not just a huge collision?
