Some astronomers study how matter behaves using particle accelerators.
Some astronomers study how matter behaves using particle accelerators. This is a device that uses electromagnetic fields and beams to contain the particles.
Scientists use 'spectroscopy' to study distant stars and they use spectral lines to study planets
To compare and classify stars.
Telescopes
No. Modern-day astronomers do not use only visible electromagnetic radiation to study space. They use additional bands of the electromagnetic spectrum to study space, including radio, microwave, infra-red, ultraviolet, X-ray, and gamma ray. Darn! That's just about everything.
Telescope
Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
the astronomers use Absolute magnitude
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 infrared light to map the dust in between stars.
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.

Telescopes
they use tools.
Spectroscopy.

the sun
There was a cluster of stars that the astronomers were studying carefully.
Collectively they are called Astronomers and Astrophysicists. Either professionals or amateurs.There are many types of astronomers, defined by how they study the stars. The most well-known are those that use optical telescopes followed closely by those that use Radio-telescope to pick up wavelengths other than visible light. there are many others and many other ways to collect data on the galaxies and stars.Astrophysicists are astronomers and may also collect direct data, yet they are more interested in the working behind the data. They deal in physics and theories of the galaxies.
