The part about the energy in the feather hitting the floor being larger than that collected by all radio telescopes ever was _genuinely_ mind blowing.

@Lucius Chiaraviglio It is. You just can't measure anything around the sun.

@Bran Arnold That's the reason behind the sheer size: radio waves sources are generally far away and really weak. For example one of the most important radio frequencies in radio astronomy is the 21cm hydrigen line. It's emitted by a hyperifne transition in the hydrogen atom and it's used to calculate spiral galaxies rotational velocities: the wavelenght is really long, meaning low amounts of energy are emitted. Also, the resolution power of a telescope (how small of an angle can be where it can resolve two things separated by said angle) is wavelenght divided by diameter. So for such long wavelenghts a reaaaaally big diameter is needed

Wir sind bewusstlos, wenn wir schlafen oder ohnmächtig werden. Wenn wir bewusstlos sind, wir haben keine Gedanken, keine Emotionen und können die Welt nicht sehen. Wenn wir bewusst sind, wir wissen alles. Bewusstsein ist Gedanken, Emotionen und alles in der Welt. Dieses Bewusstsein ist eins. Wird das Bewusstsein zweigeteilt? Bewusstsein ist nicht teilbar. Spürst du zwei Arten von Bewusstsein, wenn du mit einem Freund sprichst? Das Bewusstsein wird nur als eins empfunden. Bewusstsein ist eins. Ich bin Bewusstsein und ich bin die Welt. Evangelium nach Thomas "Denn viele der Ersten werden die Letzten sein und werden zu einem einzigen." Jesus sagte: "Zwei werden sich auf ein Lager legen; einer wird sterben, einer wird leben." Aus diesem Grund sage ich, Wenn einer alles ist, wird es voller Licht sein, aber wenn einer gespalten ist, wird er voller Dunkelheit sein. Jesus sagte: „Warum wäschst du das Äußere des Bechers? Verstehst du nicht, dass derjenige, der das Innere gemacht hat, auch derjenige ist, der das Äußere gemacht hat?" Jesus sagte: „Ich bin das Licht, das über allen Dingen ist. Ich bin alles: aus mir ist alles hervorgegangen, und zu mir ist alles gelangt. Spalten Sie ein Stück Holz; Ich bin da. Erhebe den Stein, und du wirst mich dort finden." Eine [Person sagte] zu ihm: „Sag meinen Brüdern, sie sollen den Besitz meines Vaters mit mir teilen.“ Er sagte zu der Person: "Herr, wer hat mich zu einem Teiler gemacht?" Er wandte sich an seine Jünger und sagte zu ihnen: „Ich bin doch kein Teiler, oder?“

Can we all just take a moment to appreciate how good of a guide John is? Presenting technical (and quite elaborate) information in an easy to understand manner, coupled with little quirks and bits of trivia about the facility without skipping a beat. I assume he has done this many times, but wow! A round of applause!

Tom as a seventy year old Australian I have to say I am very jealous. I have seen the dish from a distance but not up close and personal.

Highly, highly, HIGHLY recommended everyone watches "The Dish" from 2000 (starring Sam Neill and Patrick Warburton) -- it's a comedy movie about how a town in rural Australia was chosen to transmit around the world the images from the 1969 moon landing, and the technological challenges they faced way back then. Aussie humour and cinema classic👌🏻

I’ve worked on a couple of programs about the dish, in 1984 and 2000, and apart from being able to crawl all over the structure etc, the most memorable part for me was chatting with the astrophysicists working there over dinner. Their descriptions of deep space etc blew my mind.

This was abbsolutely and incredibly fascinating, all the tech in use and all the details you captured, then explained in laypersons' terms. I was picturing a "full tilted" position and saw the edge 60+ feet up; I did NOT expect the rim to come within a few feet of ground! Thank you for taking us on so many grand adventures, Mr. Scott!

Now, do yourselves a favour and watch THE best Aussie made movie I've ever come across: The Dish (2000). Classic Australian humour at it's best, wrapped around the real life dramatic event of the moon landing. Still one of my all time favourite movies.
hcblue Před 5 dny
It wasn't until the last 10 seconds that it actually hit me what "tilting the dish towards the ground" meant. For _several_ minutes, I was like haha, Tom's gonna do camera magic and 'hop' off the side of the dish. Just holy cow, the SCALE of this thing (and the building) is so… difficult to fathom.

Being an RF engineer that worked at a step site like this but with a 72 antenna; this was my favorite video so far. Absolutely perfect.

I admire these folks for using PDP-11 computers to steer this dish! The engineers of that system can continue to be proud of what they’ve built. This whole complex is made of high-quality, long-lasting parts. Long live the great people who maintain and use this fantastic facility! Long life to the Parkes Telescope!

This feels so nostalgic to watch as I remember going to the Dish for work experience in school with John. Got to use the telescope to collect some data from a neutron star. I recommend people to visit it.

Having been aware of this telescope because of the fantastic film The Dish, I never quite realized the scale of the thing until you were walking around just under it. Nor did I think when you said "...to touching the ground" I didn't ever think that meant quite literally. Absolutely amazing it can do that!
Hans Lehmann
Hans Lehmann Před 5 dny
The way you had the feeling that you couldn't tell whether you were moving, or the dish was moving, or the sky was moving... I experienced something similar a few months ago when I took an engineering tour of the very honorable Mt. Wilson Observatory, located high above Pasadena, CA. Though built well over 100 years ago with parts that had to be lugged up the mountain by mules and very primitive Mack trucks, when you're in the 100" observatory dome and they turn the dome you think the telescope is turning, not you, the observer, on what you think is a unmoving platform. It's only when they open the outside door and you see that trees are moving by do you realize what's really happening.

As an Aussie, I need to let you all in on a little secret: John the Dish Wrangler might love his job, but he would have been really keen to see the end of Friday afternoon so that he could go home and sink a few tinnies with his mates.

Having recently had a similar experience when visiting the VLA (albeit with a static dish), I can thoroughly recommend it, if you happen to visit New Mexico at some point! Maybe you could do a climbing tour of landmark radio telescopes? 🤩 And I can tell you, observing with these beauties is even more of a thrill. Best job in the world!

Another top video by Tom Scott and crew. Seeing that massive dish tilt right down to the ground was amazing, it must have been incredible to ride it. What a treat.
BBROPHOTO Před 13 hodinami
As a deep sky astrophotographer, this is one of the videos I’ve understood the best! Really cool to see. I used to visit Goonhilly a lot as a child and the dishes there were so amazing to see, almost ominous figures. Equatorial (and Alt-az) mounts are really fascinating the way they work and are essential to what most astronomers now do. I timelapse my telescope setup pointing at the night sky a lot, but I think most people don’t quite realise they move at an incredibly slow speed making a timelapse necessary to even see the movement.

Can we take a moment to appreciate the camera operator here, who not only kept tom perfectly in frame whilst descending a moving dish, but also kept the shot level whilst doing that, without a horizon!

Guys, he just wanted to mindlessly compliment someone. It's just how some humans are.
barryschwarz Před 5 dny
If there's no horizon, how do you know he kept the shot level? And if you can answer that question, then you know how the camera operator did it. 🙂
illitero Před 5 dny
There are a good few videos like that, and I'm assuming a good portion has to do with a natural sense of balance and footing taking a more subconscious place in the mind since more focus is on placement/aiming of the shot itself. So when things go wonky and Tom is allowed the resources to get fumbly and worried, the camera operator's greater focus is on keeping Tom framed and likely holding back laughs haha

Australians have historically been absolutely obsessed with developing radio technology (one factor being that we're in such a large expansive country), so I'm not at all surprised to find out that we've got mind-boggling radio telescope stuff like this in remote areas.
Gothar_svk Před 4 dny
Fun fact: this is the telescope that picked mysterious radio signals at random times during daytime for 17 years. Then they were finally able to identify the signals: they came from a microwave oven in the facility. Source: The Guardian - Microwave oven to blame for mystery signal that left astronomers stumped
TheCaracatusPotts Před 5 dny
I'm one of the lucky few to have walked the surface, though admittedly, the dish remained static. Even used the teeny tiny lift to the focus cabin, and then had to climb down by one of the ladders, as one of the staff had called the lift back down, for his trip up. Fantastic view from up there!!

I believe the entire instrument was designed by Barnes Wallis and part of the genius of the design is that clever cantilevering means that when the collector is tilted from vertical, instead of it distorting under gravity, the redirected forces actually tighten up the focus.

One small step for Tom, at the end! I'm not just taking a phrase from space lore in a silly way, I genuinely thought from the beginning that Tom not wearing a harness and relying utterly on correctly repositioning himself to avoid tumbling to disaster was crazy risky. Then it was revealed how the curve lines up with the ground at full deflection wasn't so bad.

Tom, thanks so much for this! That gentleman's analogies w the feather and cell phone on the moon were extremely relatable. One thing that would help the video a bit, tho, would be to show a world map or map of Australia and show where this is located. I know where Australia is, but am fairly clueless about locations within Australia... Thanks!

A map would be cool, for places I don't know. FYI - The "Dish" is roughly 300km (180 miles) NW of Sydney (if you know where Sydney is).

I was at one of the large dishes we have in the Netherlands a while back, and an operator was telling me about how he had a blip on the images. Turned out to be an LED light installed in a barn a few km from the dish, the farmer got some new LED lights out of that.

As a radio astronomer, I was so happy to see this video! There really is nothing like going up into a dish - I've been on the Efflesberg radio telescope. I've never observed with Parkes, but I have with another Australian telescope, ATCA (they're both operated by the same institute). It's an amazing feeling when you're observing remotely from the UK, and knowing that you're responsible for such huge things turning and looking at astronomical objects for you. You might be sick of radio astronomy now, but you have got an invite to Jodrell Bank Observatory in your suggestions submission form! Come say hello next time you're up this way. :)

@David Lowery epic
zyeborm Před 3 dny
@Jett Nash in short yes. In longer form kinda. The satellites operate on different frequencies mostly to what is being observed and in some places starlink is turned off around the telescopes. If you take a look at their coverage map you'll see a big missing circle in western Australia. That's over the square kilometre array that's being built there. It's much more of an issue for optical astronomy. SpaceX are at least working on it now and all of their future satellites are to be at magnitude -7 so they should be invisible to the naked eye. It'll probably help by not totally flooding the optical sensors but it'll still get in the way probably.

The dish itself would make a really cool performance stage for opera. Tilt the dish forward to reveal the inside of the dish to the audience, fill it with light, use the movement of the dish as a "stage curtain" to reveal a modest orchestra and an opera singer inside the dish.

I'm not sure about every radio telescope, but there are some you can't even use cars with spark plugs around because the spark to start the combustion will get picked up. The Green Bank Observatory over in West Virginia has to keep a little fleet of diesel cars to navigate the grounds.

In this video, the creator describes his experience visiting the James Clerk Maxwell Telescope (JCMT) in Hawaii. The JCMT is a radio telescope that is used to study the universe in submillimeter wavelengths, and it is able to move to different positions to observe different parts of the sky. The creator starts by describing the process of getting to the telescope, which is located on the summit of Mauna Kea, a volcano on the island of Hawaii. The journey to the summit involves a winding road that gains over 4,000 feet in elevation, and the creator notes that the final stretch of the road is unpaved and bumpy. Once the creator reaches the telescope, he is given a tour of the facility by the staff, who explain the science behind the telescope and how it is used. The JCMT is one of the largest and most advanced submillimeter telescopes in the world, and it is able to detect radiation from cold, distant objects in space that cannot be seen with other types of telescopes. The creator also gets to take a ride in the telescope's "observing cabin," which is a small room located at the base of the telescope's dish. The cabin is used by the astronomers to control the telescope and make observations. The creator describes the experience of being inside the cabin as "surreal," with the telescope moving and making slight adjustments as it tracks the sky. The creator concludes by noting that the JCMT is just one of many telescopes located on Mauna Kea, and that the location offers some of the best conditions for astronomical observation in the world due to its high altitude and clear, dry air.

As an asbestos expert from the NY City area, I approve of the Australian asbestos warning sign! Love to see how asbestos is regulated around the world. If you had a video on asbestos in your travels, I’d definitely be interested!

When the dishes motion was sped up at the end it reminded me of the time-lapse films of sunflowers following the Sun. It's amusing to realize natural selection resulted in a tracking mechanism ages before Barnes Wallace. His brain was certainly a product of natural selection so the latter once again produced an ingenious tracking mechanism.

There was previous video that had a similarly enthusiastic and informative expert guide Tom was interviewing although I cannot remember the exact details. I think it was maybe a waterworks or bridge-works?

That was actually a fantastic explanation! I had no idea so little energy was collected, we know so much from little information. Also: the Alarm it sounded reminds me of regional footy games. Noice
Yes, it was quite an interesting excursion to the plate. All the time it seemed to me that it was about to take off. Thanks for this video.

The part about the energy in the feather hitting the floor being larger than that collected by all radio telescopes ever was genuinely mind blowing.
After seeing Tom all harnessed up and clipped onto the safest walkway Ive ever seen for the high dive video its funny seeing him here completely free walking along an absolutly giganstic tipping bowl.

@Matteo Maximov You could tell when some of the questions Tom asked were about more specific parts and John looked both slightly surprised and really glad to hear those specific questions

If you haven't seen the movie "The Dish" then I thoroughly recommend finding a copy somewhere and watching it. It's a reasonably historically accurate portrayal of the Moon landing through the eyes of a suddenly temporarily important country town in 1960's Australia.

John was a great guide. Knowledgeable and so enthusiastic
gaforb Před 4 dny
The mic drop moment (or feather, in this case!) at 2:30 is an incredible bit of information and such a powerful demonstration of just how much effort goes into radio-astronomy. And tom's look when he hears it is a testament to that! Brilliant video, and brilliant guide work from John.

0:00 They've gone through a lot of trouble to make the surface of the dish accurate, so I'm surprised they would have the manhole cover protruding up like that when closed. Why wouldn't they have made it flush with the surface? At high frequencies, wouldn't that cause a noticeable phase discrepancy in the received signal at the focus?

This is fascinating, and I am amazed that no safety equipment is used, but I can see how it could cause damage... and if worst comes to worst, well, you're on a giant slide.

This is amazing - thank you for going places I never would go to and speaking to people I never would (be able to) talk to. I owe you much regarding my horizon! Thank you!
I'm not entirely sure where I expected it to end, but I spent this whole time wondering why there was no harnesses or anything, because what if you just fell off the edge. I was entirely unprepared for the dish being so big that, fully tilted, it just... touches the ground.

If you found this interesting I’d definitely recommend the movie “The Dish”. Hardly anyone’s heard of it (near me anyway) but it’s a great, heartwarming and funny film. Def worth a watch.

Might be interesting to know this is a part of a three-way telescope system, the others located in Madrid (well, on the outskirts of it, of course) and California, and they are used to maintain a continuous, global coverage for communications with astronauts and satellites.
Mashy Před 2 dny
That's actually the Canberra (Tidbinbilla) complex, not Parkes. One of the dishes there is tracking Voyager 2 right now, and will then be tracking Mars 2020 (Perseverance rover) after a 1 hour 20 minute break.
