I am not an astronomer, but I remember the first time I read about Einstein rings I thought they would make a wonderful window into vast distances. Many decades have passed since then, and now at 75 years old I just watched your video on that exact subject. I really loved this video and the complex methods used to see so far. Thank you very much.

It is also named for the tolkien name for Venus Earendil, spelled diferently but still the same star. It was the holiest star to the Elves as it was actually one of the Silmarills crafted by feanor and all three were stolen my Melkor/Morgoth, one of the Valar. Earendil gave up his gift of humanity's death as he was half elven and could choose his path of Elf or man, and came to valinor with the Silmarill reclaimed by Beren and Luthien, one set of his grandparents. Valar at eru's approve set earendil with the silmarill on his ship and placed it in the sky to lead the host of valinor against morgoth.

[@brendanotoole5871]

That ship also smote Ancalagon the black, whereupon his falling bulk broke Thangorodim... Couldn’t handle all that red shift.

Hubble, despite being 30 years in orbit, is still making discoveries--a commonly forgotten feat (Voyagers are still online, partially, still transmitting data back, for example) and should _not_ be undersold! The new doesn't render the old void of purpose.

Thank you, RJ! The cluster/sunrise arc/Earendel will all be visible to JWST twice a year. In fact the only place JWST cannot look is within 33 ° of the Sun.

It addressed questions I had from watching videos from other channels in a rigorous manner. As always, a great video from Launch Pad Astronomy. Don't forget to like and share.

the level of details in this channel is astonishing. thanks again

[@orri93]

Does gravitational lensing affect the redshift of light? If it does how (more or less redshift)?

[@LaunchPadAstronomy]

No it doesn’t, which is good in this case as the gravitational lens simply amplifies the light from the background object but doesn’t change its spectrum.

[@paulandlesson]

This channel would have made school much more interesting as a youngster. Thank you!

[@xcq1]

So, if it really turns out to be a star, this would be a magnification of around 1: 10 billion. That's like spotting a coin on the moon's surface, only through the entire cosmos. Absolutely mind-blowing.

[@LaunchPadAstronomy]

More like a magnification of 1,000 to as much as 40,000 times. Still a very high magnification though.

[@xcq1]

@@LaunchPadAstronomy Hm, you're right, that part of the paper is actually in the video. Is that maybe for the gravitational lensing alone or am I maybe just using the wrong word? I was basing my comparison on "we can see a region of approx. 1 lightyear in 10 Gly distance"

If that star is located in a volume of space that is only a couple of light years across, then this special alignment that enables us to see it would not last long. It must be of an urgent priority for JWST's alloted observation schedule.

[@LaunchPadAstronomy]

It should remain in alignment for ~few more years but the team has a Cycle 1 (first year) observation that's been accepted for JWST.

[@heyfitzpablum]

We are seeing this star as it existed 12.9 Billion years ago, not as it exists today-correct? It has taken light that long to traverse the distance between Earandale and us. Relative to our time, Earandale probably no longer exists as an active star, correct? It has likely long ago used up all it's Hydrogen. Also, since the universe is expanding that star-or what remains of it-is probably much further away than 12.9 Billion light years today?

[@LaunchPadAstronomy]

Correct!

[@johanneszwilling]

[@stevenhorne5089]

Just want to be up front. I was in grade school, in the 70's, when they decided to go to the metric system. I hated it, and proud to say I'm one of the kids that killed it. Don't hate me. I was wondering if you could do an episode on the JWST cryocooler. I watched the temp of the FSM for almost 6 weeks slowly, grindingly slowly, try to reach -400 degrees. I was so stoked the morning I got up and saw that it finally made it. Then 2 days later, MIRI blew everything out of the water as it went straight to -450. I wasn't even paying attention to it. I got gypped. There was no excitement. Do you think you could do something on the cryocooler?

[@LaunchPadAstronomy]

[@jasimine_b]

@0:04 so is the star 12.9b LY away or is its light 12.9b years old? only one can be right, no!? you're confusing me...

12.9 Gly away (billion, not million) and yes, it's light is 12.9 billion years old :)

[@jasimine_b]

@@LaunchPadAstronomy so if the light has been underway for 12.9b years, the star should be much further now, no? more like some 30b LYs?

[@LaunchPadAstronomy]

If anything, the star went supernova a few million years after its light left the star to create the image we see. But sure, its remains are now much further afield :)

[@pereloup]

I wanted to say the same thing. The star is not 12.9 Gly away. It’s a common mistake! According to the Lambda CDM model of the Universe, it’s about 28 Gly. So you are right Jasimine b.!

@@pereloup The star was 12.9 Gly away when it transmitted the light we now receive.

[@ssgpentland8241]

Amazing they were able to seen this. Since this was a "population 3 star" formed in the very early universe, saddly it has likely long since gone supernova. Indeed the galaxy it formed in may also no longer exist and could have merged with other galaxies. We will never know because that galaxy now is for beyond the edge of the observable universe probably over 30 billion LY distant now

[@LaunchPadAstronomy]

If I had to guess, I'd say we're probably looking at an early Pop II star instead of a Pop III star, but hopefully JWST can find out!

Puzzle me this. According to Nasa's website JWST should be able to see back to 250 million years. Can we image Earendel directly with the JWST i.e. find the progenitor star to Earendell??

[@aerialexplorer772]

No, because it had to be magnified circa 1000 times by the gravitational lens to be seen at all by Hubble. And the JWST is not that much more powerful. I think the 250 million years figure for JWST will allow it to see galaxy-sized objects only.

[@LaunchPadAstronomy]

JWST will be able to image Earendel thanks to the gravitational lens magnifying it so much. It’s not going to be able to see it otherwise because it’s too dim. But a galaxy that far back could be visible to JWST if it’s bright enough.
