Positions in the sky are measured by angles. The simplest is the altitude, the angle above the horizon, and the azimuth, the direction measured running eastwards from north. There are other systems but always two coordinates are needed to specify a direction.
Star positions are measured with a transit-circle, which always faces exactly south, and the stars are timed as they cross the meridian. The altitude gives the star's declination in degrees and the time gives the right-ascension in hours and minutes after a standard direction known as the First Point of Aries has passed.
I've never heard anybody use the phrase "on the sky" in any context.
You might be asking about the Milky Way, the part of the sky where we are looking through the edge of our galaxy.
Not strictly speaking sci-fi the4 film did have a rescue plot involving terrorists, and was entitled , very appropriately- Sky Riders.
EARLY astronomers primarily used mathematics; that's why so many "early astronomers" are described as "mathematician and astronomer". Until the invention of the telescope in the early 1600's, there were no astronomical tools beyond the octant.
i really o not understand the significance of the question that is asking
Astronomers use celestial spheres and mathematical equations to approximate the distances between the star and other celestial objects.
Astronomers use coordinate systems like equatorial and ecliptic coordinates to map the heavens. These systems help astronomers locate and study celestial objects by providing a framework for referencing positions in the sky.

Astronomers study the movement of stars in the night sky using telescopes and specialized instruments to track their positions and trajectories over time. By observing and analyzing the patterns of star movements, astronomers can gain insights into the dynamics of the universe and the behavior of celestial objects.
Sidereal is a term used to refer to the apparent motion of the stars. An example sentence is: The sidereal was fantastic.

These are coordinates that define the position of an object in the sky (on the "celestial sphere"). They are used in a similar way to how latitude and longitude are used, on the Earth's surface.

Astronomers study the phenomenon of stars moving in the sky by using telescopes and specialized instruments to track the positions and movements of stars over time. This helps them understand the dynamics and behavior of stars in the universe.
The device that astronomers use to find the angle between the horizon and stars in the sky is called a sextant.
No, satellite navigation systems like GPS are designed to locate positions on Earth based on signals from satellites in orbit. To locate stars, astronomers use telescopes and star charts to study their positions in the night sky.
Astronomers use azimuth and altitude as a coordinate system to locate celestial objects in the sky from a specific observer's perspective. Azimuth measures the angle along the horizon, indicating the cardinal direction (0° for North, 90° for East, etc.), while altitude measures the angle above the horizon. This system simplifies the process of tracking objects' positions as they move across the sky due to Earth's rotation. It is particularly useful for amateur astronomers and in practical observations.
