I wonder if they will easily be able to translate the IR into a visible picture. I have in my head that we'll see the same images from the start of the video, but I'm not so sure it'll work like that.

Since radio telescopes were first established the only way to see a natural light view of space is through your own telescope. You have to remember that the light that gets to earth in one spectrum could have been in a completely different spectrum when it started out. |

More a scientific impression. If the electromagnetic radiation is not in the visible spectrum of a wavelength between 400-700 nm, we can't see it with our eyes, so first the intensity of the radio emission from a particular point is translated into greyscale, then astronomers assign red to the most intense emissions, blue to the least, and intermediate colors orange, yellow and green to the intermediate levels of radio intensity. Black is for no radio emission. Since we can only see about sixteen shades of grey, turning greys into millions of colors allows us to see more detail in the image. Here's asteroid Ida taken from the Galileo satellite. On the right you can now see blue stuff you can't see in the greyscale, which they think represents younger terrain.  |

It's a scientific translation scheme with artistic overtones. 😁🤠
