- Our universe is strange, wonderful and vast, says astronomer Natasha Hurley-Walker. A spaceship can't carry you into its depths (yet) -- but a radio telescope can. In this mesmerizing talk, Hurley-Walker shows how she probes the mysteries of the universe using special technology that reveals light spectrums we can't see.

This is the type of TED talks I wanna hear about and subbed for, nice job!
I can see that shine in her eyes. She will find something amazing for us with that new telescope.
and it'll be an alien force coming to kill us
no funding :(
My countdown timer has just started. I am eagerly looking forward to hearing more from this research team and their findings.
pulakit bharti un for to nata... Thats pool game structure
pulakit bharti :) ... So far :') ; n surface tension
Her excitement is contagious. I felt my heartbeats was getting faster while i was listen to her. This is so perfect
A highly intelligent, interesting and very enthusiastic woman, whose love of the cosmos is contagious :-) She is a wonderful speaker and something tells me she will discover more amazing things in her lifetime with that radio telescope and will share with the world!!! Our universe is really fascinating to me. Thanks for posting :-)
This talk was so nerdy. 10/10
this is just beautiful...
The is the best video I have watched in a while. Amazing.
Jenish Patel
Grammar 10/10.
I had to read the comment 5 times to figure out what you meant...
Sancho Jimenez i've read multiple times and almost replied "i still don't get it" to you
It was a typing mistake guys 😅 Sorry for the confusion. Damn it, 🤗 I trust too much on this Glide typing on Gboard.
I can literally see how much she's trying to hold herself back because once she start she will not be able to stop and everyone will become bored. I'm an amateur astronomer myself and i feel very sad to see that no one seems to be interested in these kinda things, for a moment they will be like wow cool but the more you explain they will drift away looking at their watches which really hurts. I just love her she's so brilliant and i hope she reads my comment that she's an amazing powerful woman , I'll love to spend some time with her discussing about radio astronomy.
This is really mind blowing. Thanks TED for such an interesting info
Tanya Kopil 100% agree 😊
Her love of science and exploration is truly inspiring
Gave a really thorough insight into the workings of the radio telescope and did justice to how they play their own role in seeing the sky in a unique and a fascinating way. I had always presumed the radio telescope to be relatively more boring than their optical counterparts, but now seems like there is a whole universe to be explored in the field of Radio astronomy 🤩
This is incredibly mind blowing and I really look forward to see what the square kilometre array can do!
So fucking beautiful I nearly cried! I love her excitement!
Incredible! Thanks so much for sharing your work.
I watched u once in two years ago.. and I was searching for ur speech again for two years... finally I found u again... i want to share with my pupils...wonderful research and presentation
A brilliant woman with a fascinating passion we should all look up to.
Mind blowing! The Nobel is yours.
You're also a very good story teller. I can't wait for your new radio telescope. ❤️
Watching this video in 2020. The new radio telescope she spoke about is in play now. CSIRO operates the Australian Square Kilometre Array Pathfinder (ASKAP) telescope. It has already made a breakthrough in determining the precise location of fast radio bursts (FRBs) coming from 3.6 billion light-years away! Great discovery :)
Legendary woman who will change our view on the universe
This is incredible. Wanna see more of it.
thanks to TED! got to see this a week before it gets published. pretty cool.
Just watched this for the first time. VERY INTERESTING & VERY COOL!
its exceptional. the new concept is very easy to understand and very cost effective. i would surely like to join you when i grow up(i am 15 years old now). thank you for showing this to us !
Amazing ! Thank you for sharing us this great and wonderful new visions of the universe .
It,s just simply amazing with no simple work of course!
What a great video!!! that's amazing!!!
Wow! What an awesome TED talk!
Space really has the timeless beauty and that's the reason why i choose this field too, wish i can work with her in the future!
This is so amazing!!
Yes, yes, yes...just brilliant and such infectious excitement, Thank you!
feel like a small kid again learning about stars and planets. magical work being done there
*Why is the public so quiet :o*
Are they amazed?
Yeah that seemed odd, but it might be due to mixing of the available audio sources. Notice how the soundscape shifts after 15:18.
I think the feminists heard that there's gonna be a female scientist talking and they assumed she's gonna talk about how the patriarchy tried to push her down but she fought and won...
The jokes went over their heads, there was no cheering for all the achievements she mentioned, because they didn't understand the matter well enough to recognize the significance of her discoveries.
Frankly I was surprised they knew to clap when she was done talking
Right? Uptight assholes, she should've been cheered at when revealing the radio galaxies.
because everyones so loud ;)
@@procrasti86 i tried so hard not to lol at this. I failed.
Amazing concept. Best of luck Natasha and Team.
Natasha that was awesome. Thank you.
Oww really a nice way to increase the area of telescope! Masterpiece. Want to work in such motivating environment
Fabulous and really enjoyable information by heart.Keep it up.
i would like you to keep sharing what you find either through ted or through any other website.
Amazing! It felt like a journey and as if I was in it. Kudos.... bravo...
the joy of being an astronomer.
WOW. Absolutely stunning
Finally something worth sharing
I am awed to be able to see this. Thank you for sharing. She had me hooked. And then she said "That's not all" and wow was she right! Please show us more as it becomes available.
An example of humanity well spent, right there.
The force is really strong with this lady.
Beautiful just beautiful
wow this is really fascinating
I want to work with her!!! ❤️ Just want to crunching the SKA data, she can do the astronomy bit ❤️💚💛
Awesome, cleared my doubts. I was just thinking how we give colour to radio images.
* The Beginning of Time Itself *
Mind-blowing
Love this Ted talk! :)
Amazing !
Fascinating, just fascinating
very informative!
Wooo! my home town creating the worlds most powerful radio telescope which will peer into the cosmic microwave background. You bet this is inspiring, especially since you had undergrads help build this. Love for astronomy has no bounds because the journey is truly endless. The future is looking bright thanks to people like her.
awesome, i undesrtood all what she said. she's passioned. i love her discoveries.
Simply AMAZING
Beautiful!!!
Damn girl. Great work! And I bet you have parents out there just beaming with pride.
Phenomenal!
What a beautiful style of telling, when she finished i felt like i woke up to real life from a fairy tale .wow! I wish you tbe best.
Mind blowing 🤯
Finally a real Ted Talk.
When you really want to get down to business you begin exploring inner space.
I need that GLEAM picture for background! And preferably before next week :(
Guess I'll have to wait for next week
ambulance-light corelation is the best analogy so far
is it really an analogy if its actually the same thing?
its like saying lightning is an analogy for electric discharge
Random Schmid it's an analogy. It's absolutely not the same due to light's relativistic nature.
@@MaZe741 it's definitely an analogy, both waves are of different types. Sound wave is longitudinal, light is transversal. Not to mention how fast light wave moves.
We are proud of you.
Does anyone know why in the mapped image their is a large dark/completely black section? I am sure the explanation is easy, just curious; thanks.
fantastic
awesome, i hope you succes and always
Amazing
What is Gravitational imaging. I am interested to know, how we can get the details of a neutron star, which is many light years away from us. Like a telescope can we imagine a Gravitoscope for observing distant neutron star because they are very small 30-50 km diameter in size but have very strong gravitational field ?
Mind blowing
and to add, this is the best video i have ever watched after guardians of the galaxy 2 trailer
Fantastic
Just awesome
very very nice
At 10:46, supernova remnants look similar to the Event horizon Black hole image ??
ليس شرطاً أن تكون المحاكاة دقيقه ولو كان شرطا بعملوا محاكاة واحده وبصنعوا كل اشي مثل عالمحاكاه.
يسعدلي هالمحاكاه
that was just mind blowing!
Estefany Jimenez agreed 😁
Estefany Jimenez agreed 😁
Crazy... Enuf to drive love for space..! 😍😍
My ears are still ringing with that ambulance passing by
Images of the year
Is there an article with this image comparison ?
this would be interesting to explore once it's updated in space engine.
Could we find galaxies in the other spectrum's of light (other than visible light and radio waves) ?
when was this talk?and has this project been completed?
She is beautiful! I would love to meet her one day!
So how does this array compare to the TMT, and the other two?
মন্ত্রমুগ্ধের মতো করে শুনলাম
good video, especially since the telescope seems kinda low-cost
wish she would give more technical data how she generated the image, its kinda breathtaking. I didnt really understand the difference between false-colored and just giving the frequencies a color. It seemed like she didnt have much time to explain a lot of details
Random Schmid As far as I've understood it, false colour is just assigning colours to various different elements. What she has done is just compress all the frequencies, from far below to far above the visible spectrum into only the visible spectrum.
I think she just focused on infrared waves. She calls it the radio telescope for a reason (as the radio waves are far below red).
Like she showed on the graphic, we only see a fraction of wavelengths. There are certain animals and insects, which can either see or sense a wider range than us, but that's still nothing compared to what we're missing out on.
Since we cannot see anything below red, we can't have a color assigned to those frequencies. If we did, that would be a completely new color. One we have never seen before.
The way I think it works (vastly simplified though)... To generate the image, as the telescope detects spikes (which are nothing but numbers at this point), the cpu puts them on a black canvas as a white dot.
The more dots in an area, the brighter it gets. But there's a value to each dot, as they all started off as a precisely measured number.
So if you take your time to analyze the overall range of all the readings you get from your telescope and calibrate it to the threshold most relevant to you - what you end up with are values you can sort out from lowest to highest.
Now knowing that red tends to be the lowest wavelength we can see, and blue is the highest... It makes sense to tell the computer to assign the values it got from the telescope to the rainbow of colors you're used to in a way Natasha did.
The outcome helps us visualize what's going on and, who knows, maybe even represents some features the way they actually look.
Signal coming to us from soooo far far away converted into readable data and then reconstructed into an image. If that doesn't blow your mind, not many things will.
Congrats
YAAASSSSSS GIRL YASSSS!!!
Yesss
nice
Another astronomer restores my faith in humanity.....
Mrs. Hurley-Walker if you are reading this, keep in mind the double lobed objects you are seeing with the radio telescopes are birthing galaxies. Keep that in mind. There was no big bang, the matter is coming from out of the central regions of a galaxy and it is growing. The dead cores of galaxies are giant clusters of stars that will continue to dissipate, the "dwarf galaxies". What we are dealing with here is a universe that is beyond measure in both time and space. A universe that recycles itself infinitely. I suggest reading Mr. Halton Arp's work and Victor Ambartsumian who himself proposed this type of mechanistic galaxy formation back in the 1957 Solvay Conference. He was laughed at for supposing it, and all the other scientists were embarrassed by him. Yet, here we are, 60 years after the fact... seeing these growing galaxies with matter coming out of their centers, just like Ambartsumian proposed.
An incredible imagination!
although that is the definition of false color.... I understand what she is trying to say, that it matches that the lower frequencies are red and the higher frequencies are blue... and its not just some random person "fakely coloring it in" ... but that is still "false color".... its using color to aid in the visualization of non-visible processes..... otherwise great talk.
whoa
more space stufffff(:
