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.

Why do astronomers say on the sky rather than in the sky?
I've never heard anybody use the phrase "on the sky" in any context.
What is a word astronomers use to describe any fuzzy patch in the sky?
You might be asking about the Milky Way, the part of the sky where we are looking through the edge of our galaxy.
What was the name of a borderline science fiction film that dealt with the use of Hang Gliders in a rescue plot?
Not strictly speaking sci-fi the4 film did have a rescue plot involving terrorists, and was entitled , very appropriately- Sky Riders.
How much do astronomers use spectral analysis to classify stars?
a lot
What scientific skills did early astronomers use?
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.
How do astronomers use the celestial sphere to plot a star's exact positions?
Astronomers use celestial spheres and mathematical equations to approximate the distances between the star and other celestial objects.
What does the Astronomers use to observe the sky?
a stethoscope

What do astronomers use to view objects in the sky?

What do you use to measure the angle of a star?
The device that astronomers use to find the angle between the horizon and stars in the sky is called a sextant.
If Galileo used a telescope to investigate the night sky why did his fellow astronomers not use a telescope also?
this is one of my questions for homework
How can you use a cluster of stars in a sentence?
There was a cluster of stars that the astronomers were studying carefully.
What location does NOT use latitude and longitude?
The sky. Astronomers use right ascension and declination as coordinates for locating stars, rather than latitude and longitude.

How do I use lenses in a sentence?
Lenses can help people to see better. Lenses are needed in telescopes for astronomers to see distant things in the night sky.
How does a constellation work or do?
before maps, compasses, and sea charts, the position of the stars told travelers what direction they are facing some astronomers also used them for calendars. +++ The individual stars in a constellation have no actual connection to each other, but astronomers still use constellations as "sky-marks" to help find objects or areas of sky of interest.
What are the different ways astronomers use to study stars?
the astronomers use Absolute magnitude
