Frequency or wavelength is used in the spectrum of astronomical objects in order to identify which chemical elements are present in the stars.
the astronomers use Absolute magnitude
Astronomers use infrared light to map the dust in between stars.
spectrocity...absorption of select frequency of light ie spectrocity
Because visible light is emitted at a known frequency (a time) and then it is as simple as Speed = Distance / Time therefore Distance = Speed x Time.
Millimeter wavelengths are short frequency radio waves astronomers use because they can see gases and other phenomena not visible in visible light. MM wavelengths are usually used where the air is dry so water vapor can't scatter the waves.
They use the bathroom like anyone else in a house or building. They use the restroom, they are astronomers, not astronauts.
Astronomers can use their eyes to study the stars. They can also use various telescopes that either refract, reflect, and detect exotic formations.
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.
telescope
Yes
Astronomers use a telescope to view planets directly.
Astronomers use luminosity to measure the total amount of energy a star emits in all directions. By knowing a star's luminosity, astronomers can calculate its distance, size, and temperature. Luminosity helps astronomers understand the life cycle of stars and their evolution.
