Betelgeuse and Rigel are both really big stars a few hundred light years away. Sirius and Procyon are also quite big and only around 10 light years away. They are all among the 10 brightest stars in the sky, but still pale compared to Mars and Jupiter. I would imagine Stephenson 2-18 from say 600 light years away to be a very similar sight to our brightest stars. But having it perhaps 20 light years away, I guess it could look as bright as Saturn or maybe even Jupiter.

Well, 10,000 light years is pretty damn far. On the scale of a star, not much happens in 10,000 years. Most stars that we think are "close" to death are still sometimes millions of years away from death, and if we were looking at a star 10,000 light years away, it would have to be at the very very end of its life for it to be gone by "now". But even the concept of "now" isnt very clear over vast distances like that. Its pretty hard to think about two events thousands of light years apart happening at the same "moment" so we just consider the light that reaches us to be "now". I love looking up at the stars at night, thinking about the journey the photons that are currently in my eyes must have taken. Some stars appearing as they were 5 years ago, some 30, some 100. What I find more interesting is that a lot of these photons took more time going from the core of the star to leaving it, than they took travelling across space to reach the earth. Honestly, space is just ridiculous. We have unimaginably tiny things making up unimaginably huge things, and here we are trying our best to observe it all. The farther out you think, the less everything makes sense.

Most red giants and supergiants eject most of their mass and become much less dense when they exit the main sequence. I remember reading that one of the largest is only 10 solar masses.

@@sea_space That's what I thought! VY Canis Majoris and UY Scuti both do have mass estimates stated on Wikipedia though, 17±8 and 7-10 M☉ respectively, so I didn't get why Stephenson 2-18 gets a different treatment. Maybe because it's a lot farther away, making its interactions with other bodies a lot harder to measure?

The photons take 7 hours to travel UY's circumference. That blows my mind.

I just discovered your channel. And I love it!!

A MOST excellent science video. Truly educational. Thank You, SEA

Hey Sea , I have been watching your videos for a pretty long amount of time and you never cease to amaze me. you always inspire me to become an astrophysicist and answer the questions about the universe that nobody has ever answered. Great content as always !

Would love to see you collaborate with Astrum on something about the Perseverance mission

Excellent video! Not sure why but your voice is very soothing and relaxing to me. I'm fighting the urge to take a nap even though this content is very engaging lol

I watch videos like these before bed so I can dream of space.

Good God - I clicked on this expecting some KZread BS video full of dramatic music, exaggeration and dubious claims at best. Instead I found a true gem. Thank you :)

Just remember this: there is always a bigger fish.

This is great and quite comprehensive! Thanks for sharing.

Amazing video. Thank you so much for helping everyone get excited about science! Astronomy is so strange and fascinating.

That was awesome. Thank you for this well rounded compilation of large stars.

Am I the only one who falls asleep to these kind of videos?

Makes you wonder what's out there. I bet there's stars that would make Stephenson 2-18 look like a grain of sand. Can't wait to see what they find in my lifetime.

Incredible video! It is a shame that I have discovered your channel now. But people say: "better late than never". Thank you for the effort to make such a masterpiece and it is for free. To all of us!

Damn, Stephenson 2-18 is a seriously chunky chunk! Love this content. Also, ''zone of avoidance'' sounds so cool! Also, also, does anyone know what's happening with Eta Carinae? I thought it was a potential supernova candidate?

You might say it's the Stephenson 2-18 of astronomy channels.

I often wonder how we "know" about certain things like this. Thank you for explaining how we, as a species, have come to know about the distances, masses, and luminosities of these stars.

The size of the universe is true amazing and terrifying all at once. I love learning about space and all the wild stuff that goes on in it. But it also reminds me just how small and fragile we truly are.

SEA your videos are truly spectacular and one of a kind. I’ve been studying astronomy since I was a little kid, when I first sat in the front yard and looked out into the night sky. My dad told me the stars were millions of miles away, and that moment captured my imagination and never left. I’m planning on going back to school to study physics and astronomy to hopefully make my mark on science one day. Thank you so much for the inspiration, and never stop reaching for the stars :)
