The basic reference point in astronomy is a direction defined by the intersection of the plane of the Earth's orbit with the plane of the Equator. It is called the First Point of Aries and the Sun is near that point around March 21.
Unfortunately the First Point of Aries drifts slowly because of precession, so star maps have to be updated every 50 years and the First Point of Aries is not even in the constellation of Aries any more.
Bright stars are also used as reference points.

How is a parallax helpful to astronomers?
Parallax is the apparent change in postion of an object when looked at from two different places. Astronomers use parallax to find how far away nearby stars are.

Where do astronomers snort coke?
They use the bathroom like anyone else in a house or building. They use the restroom, they are astronomers, not astronauts.
Is it true that astronomers use only visible electromagnetic radiation to study space?
No, astronomers also use other forms of electromagnetic radiation, such as radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays, to study space. Different wavelengths provide unique insights into different processes occurring in the universe.

You use the F4 key to cycle through the different reference types in Excel.
What is the use of UFO?
To fly aliens to different places.
What do astronomers use?
Astronomers can use their eyes to study the stars. They can also use various telescopes that either refract, reflect, and detect exotic formations.
How do astronomers study the components of the universe?
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.
