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?“

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.

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.

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.

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!

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.

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

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.

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. :)

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.

“The amount of energy the feather expended when it struck the floor is more energy than has ever been collected by every radio telescope ever” what a mind boggling comparison!

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.

no wonder a smartphone, which emits radiation in the order of milliwatts, shines as bright as a bonfire to a telescope like this, even when placed on the moon.

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.

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.

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.

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?

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.

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.

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.
