As always, a very big thank you for including all of the "ifs" and "buts" in your description of the scientific paper and star discovery. I come away feeling like the assessment of the discovery is accurate and precise....not headlined.

[jerrypolverino]

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.

[Berserker]

Why do I love your channel? Because it’s verified information and I’ve never seen you clickbait your audience with false titles. Thank you!

[erichaynes]

This is another great video Christian, this answered so many questions I had about how much magnification gravitational lenses provided + I didn't know the very first stars were so different then the one's they spawned. Thank you!

[KristinaSmallhorn]

This is super interesting!! Thank you for your awesome updates.

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.

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.

[dalekman]

This stuff is amazing. Thank you for breaking down the science!

[BenitoAndito]

Galadrial from Lord of the Rings: "I give you the light of Earendil, our most beloved star"

Nature journal: "Don't mind if I do!"

You know what I think is interesting about this video?
You succeeded in bringing "old" news in a very interesting and entertaining manner.
This way it wasn't old at al and kept me at the edge of my seat the whole video.
Thank you Christian friendly neighborhood astronomer sir ;)

[geekwithabs]

This is a really well made video with excellent content. The detail is so intricate that I could not keep up with it a couple of times :) had to re-watch it. Loved this entirely

[noobkilla]

Really good explanation, great video Christian! Believe it or not, ever since I heard about this new discovery, I've been waiting for your video!

[Volamek]

Your content is never disappointing! I always learn something new. Keep doing what you're doing. This sounds like a great starting point for JWST if they are planning to progressively look back in time. Do we know if this area in JWST's orbit will even be a viable observation point when the telescope is at full efficiency?

[guyincognito]

This was just cool, saw it elsewhere but I love your breakdowns and showing the potential flaws.

Just thought this effect was cool, essentially if you look around enough somewhere is going to be magnified like the universe makes us some additional telescope options is neat.

[paulandlesson]

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

[TheKzelaya]

Thank you for the share! Very exciting to see 😁

[xcq]

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.

[gamaltk]

Amazing video, thank you for sharing! Like others have said, this seemed like a proper look at the paper and not just a "look, the earliest star yet has been found!". Thank you for also dumbing it down but not too much! haha

[flyingdollar]

It is always so refreshing to listen to an actual expert who trusts his audience to follow and understand these complex phenomena.

[orri]

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