- This satellite will change everything. The field of exoplanets is about to undergo a revolution.
The Gaia spacecraft is going to release new data never before seen that is going to find more exoplanets than ever before. In this video guest star Sam Ryan - a PhD student at the University of Cambridge - takes you through the past, present and future of exoplanet research.

A revolution is coming in the race to find habitable exoplanets: planets around other stars. In this video, a PhD student at the University of Cambridge interviews professors including Lord Martin Rees about the past, present, and future of exoplanets. Are we alone in the universe? Are there habitable planets around other stars? How do we detect exoplanets? And what is the Gaia satellite? All this and more answered in this video essay about habitable exoplanets.

I wonder where this video was filmed. My guess is Oxford but there’s no way to know.
The scale of the data being sourced by modern astro missions like Gaia really is pretty mind-boggling! 😳 But it's exciting the field is still so alive and our understanding of our macro-world is still so constantly changing, as new info becomes available. Love Gaia's open-source approach, seems like a truly global collab in learning more about the universe! 👏
Gaia is an insanely impactful Mission (>2.5 Papers a day on average) which sadly doesn't get talked about much. Also Sam did a great job!
Am I reading this correctly? There are more than 2.5 Papers being started/reviewed/published? about this Mission PER DAY!? How is anyone supposed to keep up with that?
@@nestrior7733 Nobody is meant to keep up with all of it. It's just papers using Gaia data. Because there is so much of it and it's so wildly applicable there are many papers that use it.
Im coming back to this video to share with a friend and im super sad to see it at only 7.7k views. This was one of the most profoundly exciting and hopeful videos ive seen in a while! Can't wait to see all the discoveries that come from this!
Its so interesting to hear different academics talk about topics they're passionate about!
Wierdly enough this Tuesday, I was at a guest lecture from Prof Queloz, one of the guys, who first observed an exoplanet and won a nobel prize at my University, but since he is at Cambridge you are probably familiar with him but it's funny timing
Edit: his paper showed up on screen
❤😊 thank you for taking over for Simon!
I felt the video was a bit flat. It was supposed to be about Gaia and exoplanets, and the information given about it was very superficial, only mentioning what Gaia will be able to do and no actual results. The only specific results were about K2-18b which not only isn't about Gaia, but talks about techniques that Gaia isn't even capable of doing. I was part of the recent exoplanet validation paper for Gaia DR3 (Holl et al. 2023), where we found the first exoplanets using Gaia astrometry, yet it wasn't even mentioned.
Very exciting video - thank you Sam! The part where Martin Rees said if he doesn't want to talk to people he tells them he is a mathematician made me laugh! :)
I would love to see the retention graph on these videos. I recently saw Tom Scott's video on how retention drops when experts speak on a topic as opposed to the host, and how that affects science communication.
If that's true, it is a very sad fact. We should be more engaged when experts are talking, in my opinion.
@@IWouldLikeToRemainAnonymous The data says such, at least it did 4 years ago when Tom Scott gave the lecture at the Royal Institution. And yes, while I love experts talking about something they love, (because I'm an engineering student who has done that kind of research where you fangirl over numbers on a screen or a getting excited when reading a paper), most people have a parasocial relationship with the host, and often tune out a little when an expert is talking. Generally it's because the expert doesn't bring a board with with them or pull out a Sharpie and a paper to draw as they talk, so their bit feels more boring than usual.
The reason we must be worried about this is because people like you and me are audiences who don't need much more incentive to click on such a video and keep watching it, but to spread science communication the video needs to feed the algorithm, but the algorithm negatively rewards lower retention videos 😐.
I'd recommend asking several specific questions instead of allowing one long rambling answer. But hey, who am I to judge these higher beings.
Man I honestly love the experts more so….. ugh
That’s a really disappointing finding
Really cool to see there's a diverse population of participants in this important field of science. Nice work.
Great video and really enjoyable....the channel is in safe hands!
Great video Sam!!
Good job Sam.
Hands up who thought Samwise already came from another planet! ✋
I heard that in classification of stars the class of "G" is "good" like our Sun is more likely to have exoplanets in their habitable zone, exoplanets around red dwarfs are likely fixed in their rotation and red dwarfs emit different radiation like microwaves ( proxima centauri).
Lovely video!!
This is very cool!
You can also figure out the speed of sound by getting drunk in a field in the middle of France.
We need more handsome and articulated science communicators in the world, and I mean hundreds to counter the sad influence of the misinformation usually found online.
10:40 OMG that's the holy grail of exo planetary study as far as I'm concerned, knowing there are planets there is one thing, being able to analyze light coming from them is massive. I want to know how precisely we can measure this light - can we infer chemical make-up kind of thing?
oh wow!
Finding them is one thing ... reaching them is something we don't even have a theoretical plan for.
0:21 Imperial Guard forever!
Discussing the K2-18b spectrum as evidence of biosignatures is misleading, given the DMS 'signal' doesn't pass standard statistical tests for a detection.
How many times can Sam say Cambridge 😂 Good video though
hmm yes this data will be very useful in my next playthrough of starfield
What is galactic archaeology? Is this man a space Indiana Jones?
bummer he doesn't have a youtube channel
Find all the planets you want, but you're still facing a staggering impediment due to the fact that Earth's been around for many billions of years, and no extraterrestrials have ever visited it. That should tell us something right there; almost like we're looking for the wrong thing.
"This satellite will change everything." - When was this recorded? You keep using the future tense "will" when speaking of Gaia, but that satellite is well into its mission and the team has had a few data releases already.
As I understand it, identifying exoplanets requires a number of years of data collection, the next few years where Gaia will release more data will "change everything" in terms of identifying these planets.
I have a similar physic and I can advice you to wear scarves and turtle neck sweaters, it'll suit you well 👌
Either I don’t find it interesting or didn’t really understand it 😐
Claiming planets are "habitable" is misleading. Almost certainly none of the planets discovered with be habitable as the average English reading/speaking person will understand that word.
This satellite will change everything, and by everything we mean only finding exoplanets which is a very very very very very very minuscule subset of everything, and will impact basically no one.
Exoplanets are cool and interesting, but they are not important in the slightest on the grand scheme of things.
Lol this twirp is just CRINGE. 😂
twirp??? smh at least call em a twink... /s /s/ s/ /s /s /s /s /s /s /s /s /s /s
