What are the 4 variables astronomers use to classify stars?
Astronomers use temperature, luminosity, size, and color to classify stars. These factors help categorize stars into different spectral types and determine their position on the Hertzsprung-Russell diagram.
What do variable stars help astronomers measure?
Distance.
The light from stars are used to determine what?
The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.
What is a constellation to modern astronomers?
To modern astronomers, a constellation is a defined region of the celestial sphere that contains a specific group of stars. Constellations are used as a way to organize the night sky and locate objects for observation and study. They are not physical groupings of stars, but rather arbitrary patterns that help astronomers navigate the sky.
How many Constellations do astronomers recognized?
Astronomers recognize 88 official constellations, which form the basis for dividing the sky into different regions to help locate and identify stars and celestial objects.

Why does the colour of the stars tell you about it?
The color of a star can provide information about its temperature and age. Hotter stars appear blue or white, while cooler stars appear orange or red. This color can help astronomers determine the star's stage in its life cycle and characteristics like size and brightness.

Who looks through telescopes at the stars?
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.
How can astronomers tell how old the universe is by looking at the stars?
Well I think its because stars flake and burn out when their really old so that could help them tell.

What used to help humans determine the temperature of stars?
spectral analysis

How could caravans passing through Babylon be helped by astronomers?
Astronomers help because they can help measure the time, or what day it is for the caravans.
Why is mathematics important to the study of stars?
Mathematics is important in the study of stars because it allows astronomers to model and understand complex physical processes that occur in stars, such as nuclear reactions, gravitational forces, and electromagnetic interactions. Mathematical equations help astronomers make predictions about star behavior, formation, and evolution, and can help uncover new insights about the universe. Math also plays a crucial role in analyzing observational data collected from telescopes and other instruments used to study stars.
