- The Voyager spacecraft are more than 20 billion km away from us. Launched in 1977 to explore the solar system's outer planets, Voyager and Voyager 2 continued their journey after completing their primary missions. Today, Voyager 1 is the farthest man-made object from the Earth. At a distance of 21 billion km, even signals take hours to reach there.
But have you ever wondered how NASA is still in contact with these two spacecraft? The answer is the Deep Space Network! But how does it work? The second episode of 'Ever wondered' answers it! - วิทยาศาสตร์และเทคโนโลยี
This is one of the best Astronomy channels on TH-cam
Thank you so much for the love!
@@TheSecretsoftheUniverse how abt any evidences of extraterrestrials visiting our earth ?
Couldn't agree more!
Along with this channel, V101 Science is another amazing channel.
@@TheSecretsoftheUniverse is the narrator a robot? doesn't sound real
Can't help but wonder if anyone else is picking up these signals.
Sadly that is unlikely. Not because of an absence of life. But because of our tech
What are the chances an alien species makes tech that is compatable with ours?
@@laserlights9684 NASA needs to stop the search for intelligent life, and start searching for it on our planet first! 🤣🤣🤣
@@donkeybutt3239 lmao good one
@@laserlights9684 I wouldn't really say it's an issue of technical compatibility, more an issue of understanding. Radio waves, being a form of light, are likely to be detectable by any advanced civilization, and they'd also be likely to recognize at least some of the radio transmissions as artificial.
Beyond that, though, there's little to no chance they'd be able to get any meaning from the transmissions without seeing Voyager 1
I wonder how far it is right now 🤔
it baffles me as to how not many people care about this or are even aware of the heights we humans have reached. this should be talked more discussed more among individuals.
“We should focus more on our own Earth than spend it on space 🤓” meanwhile they do nothing and only .00001% of taxes goes to nasa while the rest goes into destroying the earth
hehehehe among its like among us😂

Yet people are talking about what a woman is.
Imagine what could possibly be discovered if we took all the money spent on this russian war with Ukraine (from both sides) and used it on a space programme!
love this! i was actually just browsing videos on my recommended... never expected to see such a genius!
Good luck voyagers wish you well
Thank you for this! I was wondering this right now, and you solved it! Thank you so much! ☺️

Awesome video with substantial information! Keep up the good work!
Ok this is happening! it's happening. I hear *voice* on this channel.
like from Dune?
This channel needs more support... it's a very helpful and interesting channel ❤️
I'm just impressed the 2 probes haven't run into like a stray rock or something and shattering into pieces
Same! It has no way of avoiding them. Just a straight trajectory.
Space is VERY empty. There isn't much for it to hit. And most of the small stuff is either really spread out (so there is an infinitesimal chance of collision) or is attracted by the gravity around large objects.
Even in our asteroid belt (which contains millions of pieces of debris), the average distance between objects is 600,000 miles (1 million kilometers)! Yep...six hundred thousand miles between objects! That's 2.5x the distance between earth and the moon. You can travel through it and never see anything.
That's why, while exciting in films, sci fi movies that show ships dodging objects in an "asteroid belt" are really Really REALLY unrealistic. I love Star Wars as much as everyone but that asteroid scene was, realistically speaking, total horse shit.
Probably the most realistic portrayal of the asteroid belt in fiction is the sequence in the book (NOT the movie!) of 2001: A Space Odyssey. They saw ONE boulder in their trip through the asteroid belt. And that was it. (And they didn't pass particularly close to that one boulder either).
Due to the presence of gravitaty(either by planets of other objects with mass),things in space mostly are in clumps so if u can avoid the clump as a whole,there would be no problem at all.

Once again, mind blown
Awesome and informing as always
best video i got so far. the animation and details are easy to get. thank you for this video.
Thanks TH-cam for making this amazing video pop up in my recommendations.
It really cool and interesting.
And I know you can post more and more.
I loved the translation and the explanation.
Great work
This is the information i am looking for about signal. Thank you ❤️
Glad it was helpful!
Just found this channel randomly and instantly loved it keep it up!
Do you like science videos?
@@TheScienceDestination yes mostly space
@@FlyingSpike I also make those type of videos. Make sure to visit
Welcome aboard!
I saw a documentary about it, sadly in a few years we will no longer receive signals from voyager 1… it’s chilling to think that it will just be floating in space till it gets somewhere
Good to know abt Indian Chandrayan contact too...
A sea of Wonders Is being reached by the means of 'The Secrets of the Universe
' thnx for this dive in wonders :) :-)
This question was always in my mind nd no youtuber given ans. Thanks for the video.👍
Really excited to know about deep space
I was wondering should we sent a device to follow the voyagers, so that it could capture the signals from the voyagers and amplify and send it to earth more efficiently for longer time.
This would help us venture further into the deep space and explore the unknowns.
There wouldn't be any point. The Voyagers' nuclear batteries will soon not have enough power to keep the spacecraft operating.
Don't you think if we send voyagers continuously like we send one every year behind another voyager so it will be so easy to send and receive signals. Like this :
(Voyager -> O -> O -> Earth)
And if the voyager dies then the voyager behind dead voyager will be the active one. Ik it might be so simple to say but maybe very hard to make it possible practically. But it's possible and it will take a lot of resources and hard work.
Soo nicely made i like the way really!!!😃 A heart from you is really nice for me !
Amazing man....... Love ur channel 😍❤️
Thank you so much 😀
Good video with good topic. Thank you for uploading.
very clear explanation, thanks
Thank you for the info
Little/less of a scramble to read all the secrets/interesting information of the universe and more listening these days after detecting a voice behind the silent news!
Great experience sir thanks 👍!
Thanks bro
Wow I didn't we still have contact with Voyagers. Subscribed!!
When i think about voyger spacecraft...
Its thrill me ...
It is thriller ...
Voyager 1 and 2 are still amazing us today as they did when they first sent images back to earth of the planets they were to study. Sad that most of the human race doesn't care.
Your video quality is just wow, which app you are using for videi editing?
Thanks! I am making videos in Adobe Premiere Pro and Adobe After Effects.

Thank you! Means a lot 😍
Next question:
How does voyager avoid big rocks in space that damages its circuitry?
Same question
It does not. Space is mostly empty, so there's very little chance of colliding with anything at all.
@@jimmoriarty8494 so does it mean that there are no rocks a size of a fist in space? And if there is, can the voyager with its AI make computation to avoid it?
@@itconsgenio It means that space is really big and the chances of colliding with anything are really small. And Voyagers don't have AIs. They were designed nearly 50 years ago and launched over 40 years ago. Any fuel left would be used for attitude control, not collision avoidance. If it hits a rock the size of your fist it's almost certainly going to be obliterated. Hasn't happened yet, not likely to happen soon.
i think you're under estimating the space there is in space.
Hope u reach 1 million subs :D
about 4 years ago NASA's cassini spacecraft had started its grand finale ; on this date(26th april) ; the end of it's journey .
Thanks for The interessting Info 👍🌍👩🚀
U r good in explaining things
Please also continue on muon g-2 experiments
Very Nice
1:00 No. Distance doesn't matter as electromagnetic waves never lose energy from distance, but from interacting with matter. And that's the main reason.
Yes it does matter because the signal spreads out and so your detector can only pick up a fraction of it which lessens over time.
Wrong too many lie.s being told.!!
@@davidweber2489 Whose lies?
Electromagnetic waves spread out as they propagate. This is the cause of the "inverse square law". Every time the distance the wave travels doubles, the power drops by a factor of 4.
Please provide subtitles also, from it, it becomes easy to understns
Great Channel 👍
Cool!!
I am eagerly waiting for the video on night sky of may plz upload it fast

Bit overwhelmed 🌎♾️🌌👁️
such a amazing visual! do you mind if you put english? bcs im not that good in listening...
The Voyagers missions the construction methodology, power supply ... are still functional for that. When things could still be done ... now it seems that everything must ONLY work with the sun, which is certainly useful in some cases but in others it is absolutely INEFFECTIVE.
RTGs are still used when necessary: the Mars rovers Curiosity and Perseverance use them, for instance. Juno is the first Jupiter mission to use solar panels instead of an RTG, because solar panel technology has improved to the point where that's feasible. RTGs are also very expensive ($100 million), so you want to use them only when no alternatives are available.
Just got a signal from Voyager with my HackRf. So cool.
Aimlessly continuing to travel further in the endless space. Only signals are sent & received !!
Aimless? It is measuring the magnetic fields and the radiation out there.

Thanks
Yes I have wondered.
If neutron star and black hole collided then what will happen?
I think black hole's horizon size will increase means black hole size will get larger
I didn't even know that NASA was still in contact with the two voyagers. How can I ever wonder how are they in contact
It’s nasa bro not isro
Yes, even if they fake it we will believe it.because its NASA,
Radioantennae array man... radioastronomy
@@renjithrjohn8135 now?
4:38 you make an implication about Voyager being solar powered here? Their power levels recede independent of how close they are to the sun because of thermoelectric generators which are powered by a radioactive core within each space probe.
They use rtg for power.😀😀
I was just thinking this I swear
And here is the answer ;)
Still have my doubts about how they managed this type of technology in the 70s😐
If you think-this is something-you should hear a good docent (leading a tour) in the National Air and Space Museum!
Why? Nothing fancy being done.
Concorde, Moon missions, proximity fuzes, atomic bombs, IBM 360 computers.. I had a desktop computer in the 70s. Are you talking about the 1870s?
Is is hard for you to believe Electricity invented in 19th century? 😂
I cannot even catch when my mom is calling me from kitchen
What if we create chain of space crafts that not only can transmit the signals faster but also can transfer the power as well
A chain of spacecraft would not be any faster - they'd actually be slower.
2:31 I am the only one who noticed the smiling faces in the antenna 🤔
What tectonic or volcano areas are there. Do they have a significance to waves.
Ever wonder if voyager 1 will come back like on the Star trek movie as v ger 1 ? Bring everything with it to its maker.
20 billion km from the earth! Wow, that's further from the earth than the closest approach of the star S2 to blackhole Sgr* at the centre of the Milky Way galaxy, calculated at 18 billion km! Impressive. Hope the stats are correct.
If we can't pick up the signals from the Voyagers anymore, how are we going to find signals from other worlds magnitudes of distance further than the Voyagers? Gus Grissom once asked during training for a space launch after not being able to hear Mission Control, "How are we supposed to go to the moon if we can't even talk between two buildings?". Interesting observation.
where is the caption button for this video??
Wait for black hole series
Just like a movie
Wow
Imagine someone got forgotten inside voyager2
Thanks DSN & ELECTRONICS ❣️
I had a dream we made contact with a world like ours but a bit different. And we were able to communicate to them on a type of phone but we would never be able to reach them
Insane
20 billion kilometers separation and you can still communicate? Okay ask Voyager to send some selfies.
There hasn't been enough power to operate the camera since 1990 when it turned back to Earth for one final picture - the famous "Pale Blue Dot" photo. After that the camera systems were turned off permanently.
It's 😎😎 interesting
How odd that NASA can stay in contact with a tiny spec in the universe and yet have their comment section turned off on their
TH-cam site.
Simple 🛰⚓💗🗣🐛🐌🛸science is great
Is it the same way they've been communicating with it for decades?
Slightly modified. As the signal has gotten weaker with distance, they've slowed down the data rate and made the Earth ground station bigger and more sensitive.
This is good... but I have still weak signal in my backyard 👍
Do they still use a 1977 computer to talk to voyager??
Editors and vfx artist
Hey can we make a device or something which can control gravitational force or nuclear forces or something like that.
I know people will think I am crazy but it's my curiosity.
I think I've read somewhere that the Voyagers are transmitting with a power of 8W, but now I can't find that information anywhere. Can anyone confirm that? Clearly the radio signal would be tightly focused but even so, the signal that reaches the receiving antennas on Earth can only be a tiny fraction of that.
The signal level from the Voyager spacecraft when it reaches earth is a billionth of a billionth of a watt (atto watts).
Using high gain antennas and cryogenic RF amplifiers to 'pick' out the signal from the noise they can still work with the signal.
It may sound far fetched - most radio amateurs (Hams) have electronic test equipment that can measure/demodulate RF power levels of - 110dbm. That is one to the power of minus fourteen, or
0.00000000000001 watts
Voyager's transmitters are each 22.4 Watts.
I 100% understand how we can "hear" voyager however, as a Radio link designer and EME Technical specialist I have my doubts how Voyager can "hear" us, at this point the problem isn't distance but azimuth at that distance and the receiving ability of a spacecraft with a dish just larger then 3m regardless of the gain. I'm very skeptical, also still running off a battery that old begs credulity.
The whole world being connected to the internet and able to communicate amongst each other >>> NASA communicating with a satellite 20 billion km away
Upgrading antenna is good but NASA should also upgrade signal sending enquipment onboard both these spacecraft.
Thank me later.
Nice animatiom

Use quantum entanglement then you can make contact instantaneous
