This is one of my favorite science channels. Because he goes very in-depth on topics of Astronomy. Most people who talk on the topic give you a surface-level description.

[yin-fire]

I love this channel, because even though the news about this topic were released days before, you can always learn more details and more information about what actually happened to get to this result. Props for that, Christian!

[waynecribbs]

Wow! Really amazing that this was done in a single transit. Thanks for explaining Transmission Spectroscopy!

[nicholashylton]

_"It's the clearest, obvious, can't be anything else, no kidding signature of CO2 ever seen in a exoplanet."_
Sounds like they’re being wishy-washy about the result. They need add a smily face & thumbs up emoji in their paper to drive it home.
But seriously... My God, this is *absolutely incredible!*

Thanks again Christian for such a well explained video on JWST discoveries. You really should get an award for popularizing JWST more than anyone else.

[bravo_]

I usually hear those news first on Fraser Cain’s, Anton Petrov’s, Scott Manley, and Dr Becky channels, but even though you upload later, you are more thorough and more detailed in your explanations. Thank you

[dmanagable]

Great work as always thank you! I do have to say though I feel sorry for Spitzer lol, it seems to be the go to example when people want to say "hey look at how terrible our old telescopes were compared to Webb, glad we're done with that garbage." Spitzer was a good telescope! It discovered the Trappist system! #teamspitzer

Really enjoyed this one. It's truly great what our technology can do; I've found myself wondering how exactly are we capable of determining planetary compositions from such vast distances. With this video, I can now grasp onto the concept with more clarity. Thank you, and as always keep up the good work.

[Mosern]

Thanks for explaining this in an easy to understand way. Very interesting stuff!

[BrownstoneAruba]

In the NameExoWorlds capmaign Wasp-39b was given the name Bocaprins named after the island of Aruba's beach Boca Prins (meaning Prince's Mouth) and its parent star Wasp-39 was given the name Malmok. Greetings from Aruba everyone.

[stayfrosty]

Your work, my friend, is priceless! Thank you

[dannync]

LPA really is the best YouTube channel for science updates. Continue your amazing work 👏🏽

[phovos]

I'm so grateful for this channel and your work!

[Voulltapher]

What a wonderful video! I had hoped you would cover further Webb findings.

[justinball]

Love your videos. Keep up the good work.

[CarlosAM]

May I ask, when can we expect to get detailed data on Trappist-1? I heard that some data was made public a while ago but I have not seen further since

[feelingzhakkaas]

very beautiful explanation ... deserves a award. god bless you Sir.

[ConnorRoss]

your videos are amazing, i love the depth you go into compared to other channels for people a bit more into space. but you need better lighting/white balance my dude!

[justexactlyperfectbrothersband]

Thanks Christian, your presentation and ability to stuff info and knowledge into my head is several light years ahead of any other channel on youtube, with a brain the size of a planet I'm glad nobody wants you to pick up pieces of paper instead! If I lived in the USA I'd have a dime to buy you a coffee (and some time to hear your story)!

[samsonsoturian]

You know Webb was worth all those billions at the rate it's shucking out new
