They don't (a whole lot) study stars for that purpose, as a typical star's life is much less than the life of the universe. They study galaxies. The oldest appearing galaxies also tend to be those farthest away, as measured by red shift. Farthest away of all are the quasars, which are still not fully understood.
astronomers!!!!! There are many different fields withing research into space all with specific names and job roles. Some include: Cosmologists Astronomers Plantologists "Space Scientist" Various engineering roles connected with space missions just to name a few :/
Becuase nebulae tell us how stars get formed so the composition, density and size of a nebulae cloud says a lot about its age, likelihood of stars forming and the type of stars that might form.
Astronomers Cosmologists Astro physasists
The oldest stars are classified as population III stars [See related question]
Typically irregular galaxies have the oldest stars
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.
An astronomer.Ans 2.An astronomer studies anything that is not on earth; many astronomers study the moon, or one or more planets, or the solar system as a whole. The study of the Universe as a whole is cosmology; the person who studies it is a cosmologist.
Astronomy and Astrophysics.
A type of explosion that some believe started the Universe.
The most common type is main-sequence stars. This is a fairly broad category; within it, the most common type is red dwarves.
Modern Astronomy is the astronomy in which we actually started looking at celestial bodies up close. Today there is a lot going on about the information of astronomy. Galileo was the first modern astronomer, just an interesting fact to throw in!
There are many red dwarf stars in the universe. They are not most common type of star.
