You do understand that it's not a real shot that you took?!
To know why Space Zoom shots aren’t real photography, you need to understand the basics of how the technology operates. The gist of it is that the Camera app can tell when you’re pointing to the sky and determine you’re trying to take a photo of the moon. From there, it will oblige your press of the shutter button, but before you get to see your crystal-clear moon pho to, it will effectively overlay it with a new texture from a much higher-resolution image of the moon. Which was taken with specialized gear somewhere alongside your meridian at roughly the same time of the month, so the texture corresponds to whatever moon phase you’re seeing
