They use telescopes, but different types of telescopes. There are telescopes for radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays, all depending on what it is you're trying to see.
It depends on the piece of music. Many use synthesisers, but some use violins
A telescope.
Telescopes
To compare and classify stars.
they usually use super computers
The Celestial Sphere.
telescope
A spectroscope is used to diffuse the light from a star into its spectrum, so that astronomers can analyze the elements that make up the star. The same sort of instrument can be used to analyze the elemental composition of ANYTHING; for terrestrial uses, the instrument is called a spectroGRAPH.
the astronomers use Absolute magnitude
Astronomers use infrared light to map the dust in between stars.
They use the bathroom like anyone else in a house or building. They use the restroom, they are astronomers, not astronauts.
They use a spectrograph to pass light through a prism to break it the light waves into its constituent colors. Then by looking at what colors are missing they can determine both the temperature and composition of the star.
Astronomers can use their eyes to study the stars. They can also use various telescopes that either refract, reflect, and detect exotic formations.
Yes
Astronomers use an auditory up on a hillside, and away from cities and pollution. So what i'm trying to say is that astronomers use an auditory to study the components of the universe.
Astronomers use a telescope to view planets directly.
an astronomical instrument for taking the altitude of the sun or stars and for the solution of other problems in astronomy and navigation: used by Greek astronomers from about 200 b.c. and by Arab astronomers from the Middle Ages until superseded by the sextant.
