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 :-)
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.
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 🤩
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
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 :)
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.
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.
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 !
@@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.
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
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 ?
sure. but that's a projection of cosmic time, not an observation. I'm thinking this project of hers should be well funded. If she can get the resolution up like she claims near the end of her talk, we'll know a lot more about... everything (literally) :)
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.
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.
12:30 What's that light thing coming out at the center of the black hole I see on every recent picture? Isn't the theory that nothing can escape a black hole? Not even light? So what is that? Is science contradicting itself for the one thousand time?
the scope made an image of half of the night sky. Did to not see the long pic they had and the distortion that had to happen to make it fit on a small flat screen. 13.38 It's call stitching.
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.

Her love of science and exploration is truly inspiring
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.
this is just beautiful...
This is really mind blowing. Thanks TED for such an interesting info
Tanya Kopil 100% agree 😊
Mind blowing! The Nobel is yours.
You're also a very good story teller. I can't wait for your new radio telescope. ❤️
This is incredibly mind blowing and I really look forward to see what the square kilometre array can do!
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!
Fabulous and really enjoyable information by heart.Keep it up.
A brilliant woman with a fascinating passion we should all look up to.
Legendary woman who will change our view on the universe
Just watched this for the first time. VERY INTERESTING & VERY COOL!
An example of humanity well spent, right there.

The force is really strong with this lady.
So fucking beautiful I nearly cried! I love her excitement!

Mind-blowing
feel like a small kid again learning about stars and planets. magical work being done there
This is incredible. Wanna see more of it.
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 !
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.
thanks to TED! got to see this a week before it gets published. pretty cool.
*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.
Natasha that was awesome. Thank you.
the joy of being an astronomer.
Oww really a nice way to increase the area of telescope! Masterpiece. Want to work in such motivating environment
Incredible! Thanks so much for sharing your work.
Beautiful just beautiful
Amazing concept. Best of luck Natasha and Team.
Wow! What an awesome TED talk!
Finally something worth sharing
This is so amazing!!
Damn girl. Great work! And I bet you have parents out there just beaming with pride.
Yes, yes, yes...just brilliant and such infectious excitement, Thank you!
WOW. Absolutely stunning
What a great video!!! that's amazing!!!
At 10:46, supernova remnants look similar to the Event horizon Black hole image ??
Amazing! It felt like a journey and as if I was in it. Kudos.... bravo...
ليس شرطاً أن تكون المحاكاة دقيقه ولو كان شرطا بعملوا محاكاة واحده وبصنعوا كل اشي مثل عالمحاكاه.
يسعدلي هالمحاكاه
i would like you to keep sharing what you find either through ted or through any other website.
It,s just simply amazing with no simple work of course!
Another astronomer restores my faith in humanity.....
Finally a real Ted Talk.
Awesome, cleared my doubts. I was just thinking how we give colour to radio images.
Simply AMAZING
When you really want to get down to business you begin exploring inner space.
and to add, this is the best video i have ever watched after guardians of the galaxy 2 trailer
that was just mind blowing!
Estefany Jimenez agreed 😁

when was this talk?and has this project been completed?
Is there an article with this image comparison ?
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.
awesome, i undesrtood all what she said. she's passioned. i love her discoveries.
"they are moving away" vs. "they WERE moving away"... we're looking back in time when we view the stars
The data she presents is truly amazing
That's a good point. But isn't it the most likely option that they still are moving away? I'd like to see the break pads that could put a stop to it!
sure. but that's a projection of cosmic time, not an observation. I'm thinking this project of hers should be well funded. If she can get the resolution up like she claims near the end of her talk, we'll know a lot more about... everything (literally) :)
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.
Fascinating, just fascinating
My ears are still ringing with that ambulance passing by
wow this is really fascinating
I want to work with her!!! ❤️ Just want to crunching the SKA data, she can do the astronomy bit ❤️💚💛
Amazing !
So how does this array compare to the TMT, and the other two?
Mind blowing 🤯
Phenomenal!
How do they know those little dots are far away galaxies instead of nearby stars?
Because you can tell how far they are based on the radio frequency you receive back
Beautiful!!!
I need that GLEAM picture for background! And preferably before next week :(
Guess I'll have to wait for next week
12:03 "When you're a jet, you're a jet....!"
Love this Ted talk! :)

Could we find galaxies in the other spectrum's of light (other than visible light and radio waves) ?

is the cn tower plus the rogers center work as a radio telescope
everyone chant the same frequency
if you build it they will come
jk
