Unsure what you want to explain or what your nine year old already knows, but generally I would start by explaining to him/her/them that these are pictures of very far away and enormous objects taken from a telescope that is located further away than the moon.
The telescope takes pictures in a different frequency band, like an infrared camera. These pictures are then color mapped to blue, green yellow and other colors that you normally see because just black and white image are boring to look at.
In the few short weeks i have used CoPilot inside of VSCode, it's been a big* timesaver; I can type out a bare skeleton of a class, and with minimal guidance for things like naming conventions CoPilot let's you simply tab+enter through each class property.
Maybe I'm missing something obvious, but I feel like CoPilot should have the ability to allow a user to define a 'class template' in the form of a block comment and then allow a user to write "make this class" or something.
*Big being it's probably saved me around two hours of manually typing out 'public property... etc.'
