Imagine that we could take control of time and run it backwards and forwards to see how the Milky Way evolved in the past and how it will do so in the future. Well, that’s what the ESA Gaia space observatory does by mapping almost every visible star in the Milky Way. This is how one small satellite is giving us an insight into the past and the future.

I always call Gaia "the most impressive space mission nobody talks about". Good to see it get some well-deserved spotlight! :)
💯💯💯
It’s crazy how much has come out of Gaia. Hubble and JWST and Parker are sexy as hell, but Gaia is just pumping out amazing data non stop.
This just begs what else Gaia has observed, seen, and taken pictures of during its mission. The technology that humanity possesses today undoubtedly has and is denying the greater public the real truth of our universe and earth. Along with The US military's Space Fence program. Space Fence will use S-band radar and will track a larger number of small objects than previous space radars: "about 200,000 objects and make 1.5 million observations per day, about 10 times the number" made by existing or recently retired US assets. Tell me the military/government does not know way more than their letting on to know about extraterrestrial anomalies Etc... and the like. (Space Fence) en.wikipedia.org/wiki/Space_Fence#History
I've never heard of this. That sensor setup was crazy! I love seeing how much data they're able to gather with such clever equipment.
It is ESA that uses experimental data. Not NASA. Basically when America puts something in space, it is a spectacular because media hype. ESA is science at the forefront, not the possible spectacular character of it. At CERN, that other multi national endeavour, people work the science. What came out was the American result 'we've found the Higs'. Hype versus science.
Yeah even by space news standards ESA missions seem to fall under the radar a lot. Which it's is a shame because they do great work.
Check the channels; IAS, CFA from 12 months ago - astro-physics seminar,
6d mapping of milky way.....
1Mbps downlink is pretty good too
What an amazing achievement this is when you think about it. Mapping the universe like our ancestors mapped their place on Earth. Imagine the adventures that will be planned with a map like that...
Don't hold your breath ; it's not like we can send people much further than the Moon
@@phpn99 Well do we know that. I don’t believe in aliens so those craft are probably ours lead by America. Here is a good book. The hidden Natzi it’s claims to have gotten ahold of classified documents of the capture of Hans Khammler. The book claims he came to America to continue the program. Then we get to element 115 which is made in particle accelerators which is a very human invention… Lastly the circumstantial evidence of Teslas inventing the gravity amplifiers needed in the craft. I think the navy patents are for a future interstellar invention when tech catches up. The current craft I don’t believe are interstellar. I read an article long ago that those older craft would take 70 years to make it to the nearest star that Ai piloted craft would have to be sent. We don’t know exactly how long it takes to make element 115 for craft it’s possible it takes over a decade for enough for a small craft double for a cigar craft. So the hacker from the UK says we had 8 cigar craft that was in 2004 so maybe 9 or 10 now. Element 115 has to be made 1 atom at a time. He didn’t find info on how many smaller craft, but that the names of the crew looked like it may be multinational crew, but lead by America.
@@phpn99 There was a time when the strongest empire on earth routinely failed to sail armies from Tarentum to Dyrrachion. If you told the Wright brothers we'd send men to that very moon on huge multi staged sticks of solidified gasses, they'd have been dumbfounded. What we know now hardly represents what is.
@@phpn99 here is a link to early what I believe ufo test done by the cia on a dummy nuke. ruclips.net/video/HjoOuAoZpow/видео.html
@@phpn99 Iran is the only country to lose life to a ufo. That’s what confirmed it for me over a decade ago That it’s ours. They even believe it’s CIA craft also.
ESA doesn't build the most famous instruments (ordinary people sometimes never hear of them at all) but from a scientific view they're some of the best :)
I wonder if it’s a result of how ESA is funded? Any scientific mission needs to keep a large number of international scientists happy (I assume) so whatever gets sent up needs to be powerful (in terms of ability to gather data).
Entirely speculation, I’ve no idea how ESA works but it makes sense haha
I've been beating the war drum for Gaia for years now, it's SUCH an incredible, and important mission. Thank you for featuring it, I see a lot of people in the comments learning about its existence for the first time, which is *fantastic.*
We're going to be sifting through all of the Gaia data drops for decades, literal DECADES to come. ESA nailed it on this one, and essentially everything else they do to be fair. I mean I personally think NASA and ESA should get, and deserve, _significantly higher yearly budgets_ than they're getting, but that's just a policy choice for all of our democracies to duke out-my point is, money spent on the European Space Agency and NASA alike are dollars well spent (I think you know what I mean when I say "dollars" lol, any and every currency is welcome to be put toward human space exploration)!!!
Last time I heard about this project was almost 10 years ago. Nice to know that the experiments are doing great!
Always makes me happy when a curious droid notification appears.
Helps me know you're still okay.
Hi Paul, thank you for covering this wonderful mission.
At the end of life, when you're asked "What have you contributed in life?" I can say as Materials Controller at e2v Technologies. In playing my part, in a team of a special group of people. To provide 106 CCD91-72 flight model imaging devices for this project.
What always amazes me in this type of mission is how such results can be reached with technologies (such as these CCDs) established in the '80/'90, produced in 2003, launched to space in 2013 and fully analyzed the results by the '20.
It's mindbogglingly to think the grand time frames that this project have to account and consider for. They are at the bleeding edge of what is extremely reliable tech, but at the same time will have to produce amount of data that can and will only be analyzed with the tech of 20-30years in the future.
I pay respect where respect is due and I tip my hat to you RUclips stranger :)
Brilliant. How did that help people to not starve to death?
@@sunnyjim1355 come on
@@sunnyjim1355 you may as well ask how for example, the US spending $30B each year on pet food helps or the trillions that the world spends on goods and services unrelated to agriculture. Why don't you complain to Putin for starting a needless war that affected grain supplies and food prices for millions of Africans.
The graphic at 10:06 is incredible. I want that on loop as my screensaver
Right on!!

To be able to measure the angle between two edges of a coin at the same distance from the Earth as the Moon is an almost incomprehensible level of resolution accuracy. Thanks for that illustration, Ian. 👁👍
What a magnificent use of technology. The amount of information it has gathered and will gather really will inform us as much as the two NASA telescopes. Bravo and Brava ESA.
Probably nothing will ever beat Hubble for total information.
Simply because Hubble's beautiful pictures got average people excited over space again.
Which increased funding to more learning.
All of these are awesome from a science standpoint, but we need a Hubble replacement soon.
Hubble is the only one that sees what our eyes see.
Paul, you are my hero! I love your videos! I am very interested in the topics you cover and you do it so well.
A great report about an under-publicised, important observatory. Great!
How is it "important"?
@@sunnyjim1355 All knowledge is important. No?
This is fantastic! I am amazed by the ingenuity we can achieve...
I've always been fascinated with it since I heard about it in school visiting NASA in Huntsville Alabama. Its contribution always seemed so massive and incredibly relevant to all forms of science and study. and I was always curious why you didn't get such fanfare like the jwst. As a photonics and optics nerd semi professionally.... The sensor array and optical engine or pornographic and absolutely one of the most beautifully designed things I'd ever seen as a younger man. Holds true to this day
The very same reason almost nobody knows about Herschel Space Observatory and that JWST is an improved copy of that ESA mission - no funds or even thoughts about PR. 🤷♀️
@@huskytail
JWST is an entirely different thing.
Giai gathers data points using near ultraviolet, visible, and near infrared., and JWST takes high resolution pictures in multiple wavelengths of infrared.(not near infrared, which is MUCH easier)
It wasn't even technologically possible to build JWST when they started. NASA had to literally invent 6 different technologies to be able to build JWST.
Also, JWST was being designed in 1990. Giai wasn't started until 1993.
@@lordgarion514 no! 😱 Really?!
Where did you get the idea I was saying Gaia is the same as JWST? I said the name I was associating JWST with, and it was not Gaia.
The idea of having a bigger mirror size telescope in the ranges of JWST is old, the exact specifics of how to build the mission, is not.
@@huskytail
My apologies.
But that doesn't make you any less wrong. LOL
Both Hershel and JWST were first thought up in the 80's.
Neither is a continuation of the other.....
I've always been fascinated with pornographic and absolutely all things I'd ever seen as a younger man.
That is, to me, a pleasant change from your latest video about war/weapons/fighter jets. And a very interesting video, thank you.
Your videos are consistently interesting and beautifully put together. Please keep it up.
The every first yt channel I ever subscribed too, and still my favourite. Thanks for sharing.
I very much enjoyed this video. One of the best I've watched, not just of yours, but of all time. This is what RUclips is for! Excellent.
Background music to your videos is stunning! Also really like your narration. Your content should replace most of Discovery Channel programs!!
Great episode, thanks! Of course I knew about Gaia, but had no idea how exactly it does all this mapping. Data-management seems to be just as big of task as building, launching and running it!
I work in a research organization in the Netherlands where the Basic Angle Monitoring (BAM) system is developed and manufactured. You can see the base plates across the primary mirrors, also made from Silicon Carbide and instrumental to the accurate performance of GAIA. We have the Engineering Model on display, next to the flat reference mirror assembly that was used for the autocollimation with the telescope assembly. What I understand is that because of higher-than-expected thermal load from the computers, the main structure expands a bit more than anticipated and would result in inaccuracies in the measurement. With the BAM, this angular change is monitored and is used in corrections.
I'd heard of Gaia satellite several times but not heard about it until now. Lovely video
Always great, well-thought-out content.
Wow, heard about this before, an incredible piece of engineering and gathering really useful information, thank you for dedication and such a great video
The technology and mathematics involved seems staggering. Wonderful video as always!
Another great broadcast, man... Very much enjoyed... Most pleasant to watch... Thank you..........
Great video! Well researched, written, and presented.
Long time fan. Love your channel! This is amazing
Excellent, truly great video and one amongst many. Thank you.
Uplink: 1Mbs (one Megabit/s)->60*60*24*1.000.000bits/day~=86.4Gbits per day~=10.8GBytes per day.
Original data is "50GigaBytes of data per day", hence after analyzing and compression only 10.8/50~= 21.6% of the size of the original data volume is left over.
I guess you'd need a lot of processing power in space to be able to do so, would be cool to learn about (the evolution of) interstellar data transmission.
Incredibly humbling. Thank you for making this video Paul!
What a stunning piece of space hardware, and a superb video explaining it - thank you Paul.
Thanks for covering this. This is one of many great telescopes that should receive even more attention.
Loved it. Thanks Mr. Droid.
This is insane.
What a time we live in.
10:05 let us just realize and admire the incredible amount of work, effort and time which was needed to create this animation 😮
So very cool. Thank you for this. Love your channel
Another great video. Thank you!
I now buy shirts with prints and patterns because of watching this guy. This has improved my life.
Thanks, Paul. Great video and presentation on Esa
Great vid Paul, love your channel.
Hello from Newcastle Aus
Mind-boggling stuff! Probably a bit late on this, but congrats on a million subs - fully deserved.
Already mapped in Elite Dangerous ;)
Gaia is remarkable project!
Awesome thankyou! This was one of the most exciting pieces of tech sentup I ever saw. P l ancient, Hubble, Switzerland. This machines freaking rocks!
I was enthralled with the engineering prowness of the Gravity Probe B mission.
Great video Mr. Shiillito, thank you!
Greetings,
Anthony
At 10:05 this is just a marvelous masterpiece of engineering: just think about how long mankind is gazing up to the stars - and now we developed technologies where we can not only track the position of millions and billions of stars but also predict their way through space and time, in the past and in the future! This is just mind-blowing 😮
It is a lot to digest, and its not something an individual layperson can do
Still the deluge of data keeps me somewhat consoled and awake. Its an amazing piece of machinery hardware
amazing video! thanks CD
Super interesting.
Great video and narration as always. 👍
Fantastic video. Kudos!
Fascinating! How come I never heard of Gaia until today? Thank goodness for websites like this. You keep retired nerds like me informed.
This amount of information is totally bonkers! Analysing to determine not only where stars (and all the other stuff) are but where they've been, where they're going, and what they're made from is mind-boggling! 😵💫
I'll bet all that data wasn't processed on a Pentium II-350! 😄
Nah, it's ESA. They're on AMD K6s right now. :D
Great informative video with cool images 👍🏻
Mindblowing!! Brilliant, amazing scientists who could design and execute this!!
really impressive engineering in its details, thank you CD
Another great video, Thank you.
This project is insanely amazing 🤩🎉 respect to all who worked on it
I had no idea. Totally fascinating!
Excellent video!
Great Video !!
Brilliant as ever Paul 🎉
Thank you for sharing the wonder of science and our universe.
The mind boggles...truly fascinating. "We are made of star-stuff. We are a way for the universe to know itself.”" Only teeny wee issue with the diagram for our distance to the Sun, perihelion and aphelion .
Phenomenal presentation. I am smarter for having watched this. Thank you, sir.
Such a great channel.
Thank you Space Varys
Wow! Outstanding description of ESA's Gaia! Gaia is an unsung hero in my book!!
I love your videos!
Great video !!!!
Very interesting video, what an impressive piece of tech this is.
Love your videos.
Truly brilliant technology, thanks Paul
💯Excellent segment❤
Nice one, clear and concise. You're good at this aren't you 😁
Thanks for sharing.
This is some true real life sci-fi stuff. Imagine coming up with this idea and then actually making it a reality.
Go Gaia!
We could use a dozen more satellites with such amazing capabilities.
wow, just wow. I've never heard of this. Our renaissance is the space age and the knowledge it brings.
So, this is basically galactic scaled 3d time lapse photography? Wow
This video is so interesting that i will send it to my friends and demand to like this content!
Absolutely incredible!!!
Always interesting but this one especially so. good work.
Always the Best Curious Droid...............Always the Best
There is a ESA mission called LISA. It's a gravitational wave detector with the baseline of the earths orbit. the Pathfinder mission already launched and proved that it's possible to levitate the sensor block inside the satellite with enough accuracy to eventually launch the main mission with it's three satellites in sun orbit.
It's an interesting story to tell - should it launch.
I would love a separate video just on the interpretation of results of GAIA - just to have a better picture about our galaxy
It is amazing how we know what our galaxy looks like even though we are essentially describing every detail of a truck from a locked windowless soundproof room inside that truck as it is being transported by a helicopter which is being transported by a cargo plane which is being transported by a bigger cargo plane which is being transported by a rocket… you get the idea
fantastic design and engineering
Good video. In this video, the figures given for the basic angle of Gaia's pair of telescopes is 106° @4:43 and 108° @ 6:33. The exact value is 106.5°.
As always a Proper Laffin Video from the Dude of the Dudeness Paul !! 💯👍😁
Fantastic!
Thanks Paul...
Fascinating.
Gaia took Hipparcos to a whole new level. Hard to grok that 1000 light years is but 1/100th the diameter of the Milky Way.
Fascinating...
Amazing!
Insanely interesting!
Wow just awesome engineering the universe is a spectacular ✨️
5:30 - it's "cubic boron nitride" that is "as hard as diamond" (...almost). SiC is "close to diamond" on Mohs scale (9.5 vs 10) but it's kinda misleading, as the scale is kinda logarithmic.
In "real numbers" and "proper units" scales SiC is less then "half as hard" - in Vickers scale it's 25-36 GPa for SiC, 115 GPa for diamond, Knoop scale says 2300-2900 kg/mm2 vs 7000-9500 kg/mm2 respectively.
(For CBN it's 48 GPa/ 3500-4750 kg/mm2, so still "room for improvement".)
And yes, it is totally irrelevant to the subject of this video, but still a "sorta blooper".
wow wonderful. I had no idea
