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.

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 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.

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 :)

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 ?

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
@MichaelBerthelsen
@MichaelBerthelsen 7 жыл бұрын
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.
@procrasti86
@procrasti86 7 жыл бұрын
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.

although that is the definition of false color....
