The Parkes Radio Telescope, Murriyang, part of CSIRO, is one of the most famous telescopes in the world: and it's got a unique way of getting equipment up and down from the central section. ▪ More about the Telescope: www.csiro.au/en/about/facilit...

    • Also remember that the signal coming from Voyager is so weak that they can barely receive it with those massive dishes, and the communications back are done using multiple hundreds of kilowatts of power, sent via the same dish, and the spacecraft will only get them more than 24 hours later, and reply also 24 hours later on. Also the voyager spacecraft were never actually designed to last that long, they were actually spare Mariner spacecraft bodies that got a massive antenna grafted on to allow communications, then a RTG instead of solar panels, and thus were sent out. Now down to a little over 200W of power for use on the spacecraft, so by around 2030 they will no longer have enough power left to transmit high speed data, and soon after that will lose all transmit power, though the computer will continue to operate, and keep the spacecraft aimed at the sun for decades afterwards, but will be mute.

    • @@davidioanhedges Yes it is small, but by the standards for the Mariner probes it was based off it was huge, and the error correction was designed to be as robust as possible, but also as simple to implement in the spacecraft as well, as complexity at the time came with added mass, and you had an overall maximum launch mass you could not exceed. Thus the panels were made from Beryllium aluminium alloy, milled as thin as possible in low stress areas, and milled away completely where not needed, just to avoid the mass of a rivet to hold a gusset in place. Remember at this time digital decoding was done using discrete chips, or using massive computers, so to put the error correction and forward error correction in the probe they had to choose between robustness, data rate and mass, choose one, because mass is the severe limit. Even the digital data recorder was special, because it had to survive in a vacuum, and it still does work now, that design and the tapes are still holding up.

    • No sophisticated technology reaches a state of complexity until it becomes indistinguishable from magic. Anyways, have a look at the concept of Fundamental Constants. You'll be amazed at the precisions in Creation. Everything in the Universe is determined by special forces called fundamental constants which are unbelievably precise. For eg. -: If the rate of expansion of the Universe would have changed only by just one part in a quintillion after the Big Bang, a quintillion is one with 18 zeros after it, 1,000,000,000,000,000,000, the Universe would have continued to expand or collapsed back on itself. How the Atmosphere (various layers) protects the Earth from destruction from meteorites is again amazing. Solar Flare which occur frequently from the Sun ☀️ has energy equivalent to 100 billion Atomic Bombs which was dropped on Hiroshima couldn't destroy Life on Earth 🌍 due to Van Allen Radiation Belt. The centre of gravitational force could have existed anywhere on the Universe which is supposedly 13.5 billion Light Years Big but it only exists at the right place that's why Life is possible. Scientists say, if it is shifted/ moved even 1 inch compared to 13.5 billion light years length of the Universe, the effects would be catastrophic & it would wreck the Universe. So, everything is on the knife edge.

  • 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. :)
