    you can see those line-thingies in the contour lines- what are those called exactly?

    Can you explain what the "line-thingies" you mean?

    you know, kind of like these weird circles going the opposite direction of the curves inside of it. You can see it if you squint.

    I see. Those have to do with the computer display and the way the contours are rendered on the screen. Nothing to do with the radio source

    oh, I looked it up. It's called a Moiré pattern.

    Aah yes, you are seeing the lattice-like structure that is characteristic of interferometric imaging.

    Interferometry correlates the signals from many spaced out smaller telescopes to mimic the observing power of a very big telescope
