The app can be extended in the future to different layers of information to show...
Space stations and satellites
The app allows the tracking of international space station, which is a habitable artificial satellite in the low orbit of the Earth. With advanced features integrated into the app, several space stations and satellites orbiting the Earth or other planets can be tracked. User would know which space station or satellite in his view, what its main mission, how far this station is from the earth, when its launched, and any other interesting information related to it. It can be estimated from its distance, for how long this station would stay in the user’s view at the current location. Additionally, the app would suggest that other space stations would be in the user’s view in a certain amount of time estimated from the current position of these stations, their orbital speed and the user’s position.
Black holes
One of the most interesting phenomenon of the space is the black hole. They are areas in the space-time that have very strong gravitational effects in which almost no objects or even light can escape its gravitational effects. The app can present information about the locations of the formation of these black holes and their estimated gravitational effects.
Occurrences of comets
Other astronomical objects can be viewed or their related information. For example, showing the frequency of comets that passed through the current region of view. Some comets are periodic so the app can suggest when a specific comet would pass this area on its way to the sun, although that would be after a number of decades.
Filtering of space objects
Information can be layered to show astronomical objects that are within the solar systems or outside the solar space. For each, clusters of stars and galaxies can be shown. Since the space is occupied with many types of objects, user can filter data according to different categories. Planets can vary from minor planets to giant planets. Stars can be categorized according to their spectral types, luminosity and their role as primary or secondary stars. The app can give the user the ability to filter and categorize what to see.
