The article discusses a website that overlays stays on a light pollution satellite map, allowing users to find dark locations for stargazing. The website uses IP geolocation to find the user's location and provides a date picker that shows the phase of the moon. However, the website has a rate limit imposed by its data provider, which can lead to errors when accessed by a large number of users. The website aims to help users find locations with minimal light pollution, making it ideal for amateur astronomers.
