Do you think stars are "alive" ?

Neil is one of the greatest personalities of our age and my favorite scientist of all time. And chuck, I love your intelligence in both science stuff and comedy. You two are incredible and thank you for all you do for all of us.

Bringing smiles to people is truly noble work. Neil and Chuck do it while educating us. Thank you, both.

Neil we need more people like you. You yearn for others to feel the same wonder that you do looking out into the galaxy, and you artfully navigate the politics of today and you do it with compassion (the thing that is humanity's greatest attribute). Thanks for all you bring to humanity.

We are watching Chuck get more and more informed with us. It's really cool to watch his thirst for information grow with us. Thank you Dr. Tyson.

I WANT MORE OF THIS! If the "buck stops at iron" then what about the even heavier elements like Nickel, Copper, and Barium? We need another explainer, or at least a continuation!

I love to watch this thank you Neil and Chuck for making these wonderful videos 😀

[carolvega]

Chuck's stunned silent face reflects my own! I love gaining knowledge! Thanks, Neil, Chuck, and Startalk!

I know time is precious, so I appreciate Neil and Chuck taking the time to produce these videos.💖💖💖

There was an episode of Star Trek: TNG where Data argued rather convincingly that fire is a form of life. It requires significant energy to ignite, it consumes fuel, it produces offspring, it dies.

Hi Neil, I just saw you on CNN with the 9 year old young man. Could you bring him on, so he can ask some questions with out being interrupted? Wow, you would be a great mentor. Thank for your shows.

[crasysyst]

I would love to just translate all your episodes to Arabic 😍 this is so much free knowledge ❤️ thank you

[holygroove]

Please continue the use of clips during the discussion! Visual learning combined with auditory! I have always wanted to 'see it' while Dr. Tyson is speaking. It's a great combination because he sees it in his mind when he's speaking.

Great work as usual. You guys make science fun. Thanks a million

[Sai-jwog]

This channel got me hooked on astrophysics. Truly fascinating!

[hakl]

One of the best episodes of star talk. Amazing Neil as usual. Need more on star, planets and galaxy formation.

[waynewynnx]

Love the new format of graphics and animations, so much easier to understand the explanation. Great work! 👏🏻👍🏻

[cooperwingrave]

Hey Neil just bought two of your books feeling good I brought a starry messenger and astrophysics for people in a hurry can’t wait to read them hope you have a good day

[crowlsyong]

I love the cohost. He is so curious and his memory serves him well. Have a great day everyone.

Neil, I just saw a news report of the youngest high school graduate. He wants to be an astrophysicist!! Please, I hope you can connect with this young man and assist him through his journey!!
