Astronomers typically look through telescopes at the stars to study celestial objects such as planets, stars, galaxies, and other phenomena in the universe. They use telescopes to gather data and make observations that help expand our knowledge of the cosmos.
Astrologers look at stars and predict events according to what they see. They are different from astronomers because astronomers have a scientific basis, while astronomers do not.
Anyone can look at the stars. Astronomers do it as a hobby or even a profession. Other types of scientists, like cosmologists, also study stars.
Scientists who look through telescopes are known as Astronomers (Astronomy). Astrologers are those who deal with the divination art of Astrology.
Astronomers have difficulty looking at distant stars because while we have highly specialized telescopes, they are in constant contention with various other celestial bodies. In addition to this, the light of distant stars takes hundreds of thousands of years to reach us, making it impossible to get a current look at a distant star.
look it up somewhere else OR just say Russia
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
The easiest way is to look at a picture of the star and then look at another one taken six months later. If it has moved, that can be seen on the photo when you look at it in relation to the stars in the background of the photo. That was the first method used to find the distance to the nearest stars, and it was a big surprise to find out how far they actually were.
These people are called Astronomers. Look it up in wikipedia if you want more information.
The Mayans were great astronomers. They built their temples according to the way the light would look at different times of day, and therefore, stars made designs on the Mayan structures.
They are the same.
