How the James Webb Telescope Looks For Aliens

Imagine aliens on the other side of the universe, today or a thousand years from now, witnessing the birth of our star with their telescopes.

Love it! But don’t forget about the possibilities of aliens that aren’t based on water! That’s even more crazy and exciting 😆😆

I started watching your Shorts when the algorithm made it's magic and then, seeing the effort you put into your Shorts, made me question if you actually post longer form videos. Turns out you do post them and NOW I am obssesed with your channel. I am a huge fan of both medicine and technology and you cover them both. As a medical student, I am in awe when I see how deep you went with the cancer video and as a tech enthusiast I cannot help but get goosebumps whenever you decide to talk about space or electric planes. You are growing to be my favourite channel for any topic, not just science. Thank you for your work, it's amazing.

Okay wow, these images are just beautiful! It's crazy that the light from these galaxies took billions of years to reach us. We are literally looking back in time! 🔭🤩 Back then when we produced our "Game of Moons" doc, we were amazed every day how many unknown things are out there. There's still so much to explore and it's so cool, that tech & science take all of us with them on this rollercoaster ride through the universe.

Sometimes science sounds more like magic, this stuff is just mind boggling incredible 🤯

That ended too soon. Once again, sponsor segment was perfection. Awesome video as always, and the excitement, it's infectious. Keep them coming, Cleo.

Its incredible how a single billion dollar project can have such a huge impact on how we view this universe .

The water molecule in the atmosphere of the planet at 3:11 should have two Hydrogen atoms and only one Oxygen atom. Also, the Nitrogen atoms should be connected with a triple bond instead of a single bond.

There's this glare you have in your eye that only comes from speaking out of pure emotion and passion! I can see how much excitement you were holding back at this discovery and that just gain you a sub!

Imagine if Carl Sagan were alive to see this... Ann Druyan must be teary eyed around now... Been following the JWST since it launched. Amazing to see it up and running so well so early - long may it live!

To put things in perspective, the light bulb was invented only 143 years ago. Now we have the James Webb telescope. Human as a species has come far.

Just discovered your channel. Mind-blowing. I arrived on your F1 explained video. Then checked the fracking video. And now this as the latest. On every of these videos i was already very well informed. Yet it was mind-blowing, to me, to see such high quality content. What impressed me the most was journalism ethic, easy to understand explanation, high quality research. It's a matter of "level". Each of these things are incredibly hard to get in journalism. It makes sense, right, one cannot be an expert in everything, yet journals are expected to report on everything. And one (one person, one team, one company) CANNOT be good at everthing, obviously. Thus when i see high level content on ONE of these three condition (ethic, understandable, documented), i'm calling it a great work. Well you (you & your team) reach that high level on these three at once. Being from Europe (France), i tend to assume that in some fields, anything american cannot be better than european (i know, that is dumb, yet americans do that too :p). Journalism would be one of them. Well, great way to prove me wrong. The only equivalent for your work would be our ARTE channel (french & german channel). You probably do not know them, so let me tell you, that is high, very high praise. Many thanks to you and your team.

Shout-out to all the scientists and astronauts out there, working and giving us these revelations... You are our galactic heroes! ❤️

The video I wanted to see, a general news and tech communicator who actually GOT IT! The most important image released, and yes this is the one that maters! THANK YOU FOR BEING YOU. (Now if we can only get Large Ultraviolet Optical Infrared Surveyor built and launched in a timely manner, your dream may become a reality sooner.)

Honestly watching you geek out about new topics always makes my day! I was hoping you'd make a video about this, thank you so much

We truly are alive during quite a scientific breakthrough. Fellow employees I work with were anxiously awaiting new pictures yesterday from the telescope and it did not disappoint. It’s only a matter of time before we find some sort of life form.

Loved the 5 mins video! I wish there was more summarized content like this one on YouTube! Keep it up Cleo :)

Love it! Good to have your quality content back on the notifications. Always a fresh, different, new and most of all a simple outlook on current affairs. Big ups to you! Love the channel 👌❤️

I've been a fan of yours since Vox and now it's great to see that you and Johnny have made the decision to focus on independent journalism. Thanks for both great content!

It's not just tiny specks of light being blocked. In fact it is just the tiny circle around the planet (which is its atmosphere) we're looking at. Just mind boggling.
