The size and color, at sometime, it will get too old and blow up, like a nova or supernova.
A young star is mostly hydrogen, undergoing nuclear fusion to form helium. As the star gets older, it has steadily more helium. Eventually, when it begins to run out of hydrogen, the helium will undergo fusion to form progressively heavier elements. By looking at the light from the star through a spectroscope, you can see markers that indicate the proportion of different elements, allowing you to estimate the star's age.

Which is not a name that identifies mercury venus earth and mars?
"Stars" is a name which does not identify them.
How do you identify a celestial object in the night sky?
An experienced astronomer will recognize the stars and the constellations; he would either know from experience, for the brighter stars, or be able to look it up in a reference guide for the dimmer stars. Anything that isn't part of the pattern of fixed stars is either a planet, an asteroid or a comet. A little observation with a telescope will tell you which. For the rest of us, I recommend a planetarium program called Stellarium, available for free online at stellarium.org. This is the program that I use whenever someone asks a question like this. :-)
How are stars in the same star cluster simalar?
similar age and composition.
What two things does a stars absolute magnitude depend?
Mass and age.
What is the age of the stars in an open cluster?
The age of stars in an open cluster typically ranges from a few million to a few billion years, depending on the cluster's specific characteristics and formation history. Open clusters are relatively young compared to globular clusters, with many being less than 100 million years old. The stars within a cluster are generally formed around the same time, allowing astronomers to estimate the cluster's age by studying the most massive stars and their evolutionary stages.
Why do astronomers find it necessary to identify the stars?
astronomy
What happen when stars age?
As with everything, stars age as well, and reach the end of their time. As stars age, they become different types of stars, based on how big they are, and how hot they are burning. When they run out of fuel, they eventually die.
How do you identify the constellation of stars?
we can easily identify constellation of stars.Constellation is a group of stars that appear to form some recognisable pattern or shape in the sky.some examples of constellation stars are Ursa majors,ursa minor,orion,cassiopeia.
How old are the stars irregular stars?
The same age as stars in other galaxies.
What could be the type of maps that will help to identify the locations?
Star charts help identify the positions of stars.
What instrument was used during the Age of Exploration to observe stars?
At the Age of Exploration they used telescope to observe stars.
Who likes to lie under the stars on clear nights?
Identify the noun
Studying Fraunhofer lines helps to identify what on the stars?
Studying Fraunhofer lines helps identify the chemical composition of stars. These lines represent specific wavelengths of light that are absorbed by elements in a star's atmosphere. By analyzing the pattern of these lines, astronomers can determine which elements are present in the star.
Do spiral galaxies have young stars middle age stars or old stars?
It has all types of stars with different ages
How can I identify the age of my dog?
I am not sure
Average sized stars will spend their old age as?
Red giant stars.
Are scientists able to identify elements in stars by studying their spectral lines?
Yes, they are.
