There is an option to subscribe to a commercial satellite imagery provider, such as Planet or Maxar, which offer high-resolution images of the earth at night and other times of day. These services can be useful for businesses, governments, and research organizations that require frequent and high-quality satellite imagery.
It is important to note that satellite imagery can be subject to certain limitations, such as cloud cover or interference from artificial light sources. Therefore, it may be necessary to use a combination of different sources and tools to obtain the best possible images of the earth at night.
