This thread is very confused.
There are two things: the radar images are created with radio waves emitted by the radar installation. The second thing is that the visualisation shows a light source. They are unrelated to each other. I assume that the light source was added during rendering of the film and that it approximates the sun.
- TorKlingberg 9y agoI don't think the visualisation shows any light source. The radar reflection from the asteroid just looks like it is "lit up"
- ceejayoz 9y agoThe radar is the light source, just like shining a flashlight during the night at something. The actual solar illumination of the asteroid at the time was likely significantly different from what we see in these images.
