✵✵✵✵✵ Measuring LIGHT in Astronomy
Just How Bright are stars, really?
From ancient times, people have been looking at the stars and deciding this one is brighter than that one. But how do you know if a star is actually brighter, or just closer to you? Astronomers use a wide variety of terms to distinguish between how bright a star LOOKS to us, and how much light it is actually producing. These terms can be very confusing! But we'll help you figure it all out.

Volta a fazer para o Brasil também, em meu curso encontrei sobre você, e desde então eu de fato aprendi, seu canal é direto e prático, somente me identifico aprender sobre formas de estudo com ele, nenhum outro até agora que conheco, é claro, objetivo e tão amplo, mas ao mesmo tempo acertivo no conteúdo aplicavél de forma prática. Quero falar que mesmo após 03 anos seu canal ainda continua ajudando muitos alunos como eu. Agradeçida e sempre sua fãn.

I used to watch this channel a lot 6 7 years back, today i got this recommended and i felt so good, thanks for teaching so much in such a fantastic way❤❤
Making a video about LIGHT is a BRIGHT idea.
So this is what quality over quantity means. Good work guys don't forget those future videos I'm waiting. 🔭🔭
I love it when Liliana takes me ro infinity and beyond! Thanks!
I just find it so relaxing to listen to Liliana talk nerdy just at the precipice of my understanding ❤️
Welcome back and delighted you hung out with us for longer than 30 seconds!
I found your channel in Portuguese and it's one of the best channels I've ever seen. Unfortunately the last video was from 3 years ago. It would be great to see you again in the socrática português.
We hope we can return soon! We recently started the Socratica Foundation, an educational non-profit to raise funds for our international videos. Please share with all the philanthropists you know! 💜🦉

Nice accessibility nod with the formulas (and action descriptions) added into the captioning!
This video was illuminating.
Happy to learn something new again from You & Liliana again ^.^
man, universe is so incredible. Awesome video. ty
I'm in love with this presenter. She's awesome. Great content, excellent delivery.
Amazing video !!! Thank you for sharing so much knowledge
Interesting as always
Thanks, Socratica. 🙌🙌🙌❤
Thanks!
Goodness, thank you so much for your kind support!! 💜🦉
I just found this channel and am a 21 year old college student and just wanted to let you know I love your videos. I went to the most recent one so you’d hopefully see this comment. Your awesome girl
Gracias! Excelente video tanto para estudiantes como para profesores. Saludos
This is lit 🎉
Really a beautiful vídeo. It is quite rare to find vídeos like this.
Not rare on this channel ☺️
@@murphygreen8484 Indeed.
Espectacular el vídeo . Espero que vuelvan a hacer vídeos en Español . Su contenido es muy didáctico y espectacular
Lovely !
Really good
Quando criança era apaixonado pela Polca, ai anos depois descubro que a mesma atriz apresenta esse canal, os anos passam mais o crush é sempre o mesmo rs
Love your videos
Adorei o conteúdo!!! Pena que só descobri agora :/ mas já compartilhei com minha filha pra que ela conheça também 🥰
currently watching the algebra playlist.
without a doubt, second best math playlist just after 3b1b's essence of linear algebra.
super interesting!
Caramba , fico tão feliz por essa Atriz e youtuber. Merece todo o sucesso do mundo. Alem de linda , é muito talentosa. Boas lembrancas de você em Da cor do pecado , Alma Gêmea e castelo e na tv brasileira. Um grande abraço. I'm a big fan ❤
Thank you for the video, hope you are well? you look very tired. keep up the good work.
I need more
please also continue the abstract algebra series.
How do we determine distance to far off stars? Red shifting?
Love for the content and hardwork, from India ❤️
A versão português não tem ? Amo ver vc falar
Faz uma grande falta o canal em português 🥲
When lumen is introduced in this video, I think the difference of radiometry and photometry should be stressed.
I miss her ❤
It's been a long time
🌌♾
Caraca, a Liliana realmente tá por aqui 😳
✨️🧚♀️🌞
But i still don't understand how you measure the distances of various celestial bodies?
By parallax, but only for stars in the Milky Way.
( 10:15 ) whats the "umm humm" about?? 🤔🤔😆😆
Excuse me but... when is the Spanish channel coming back?
I always wonder how bright the planets are. I mean if you traveled to Uranus or Neptune those planets must look like dim globes in front of the stars through the window.
Who are we really? Are we made of star dust? Are we living in a simulation?
@Ali * _Creationists_ do not believe that human beings evolved from apes, because you falsely believe yourselves to understand how the concept of natural selection works, when in reality you don't.
F.I.F.Y.
#Socratica Português
Muito vom
I MISS YOU IN SPANISH 😢
Mam, are you a professor ?
I thought the first statement was about the hemsworth brothers
😀
Vuelvan a Socratica español
pra quem está com saudades do canal em ptbr
abra um vídeo coloque legenda em inglês e aprenda inglês
é sério, a pronúncia dela é limpa, a melhor possível pra aprender
Ela parou com o canal em português por causa dos gad0s, se eles migrarem pra cá, já era, não aparece mais tbm.
@@BarbaraVizan01 gados donde?
A danada fala um ingles como se fosse nativa, que apelação kkkkkkkkkkkkkkkkkkk
Qualquer um q estude, consegue.
Why are both Jesus and Satan referred to as the morning star?
No clue, but such a question has rather little to do with understanding the concept of a star from an astrophysics perspective. In fact, it has no relevance to that at all.
Marry me?
She is married.
Respect her, s1mp.
Por causa de gad0s q ela parou com o canal em português, pqp.
