All that we know about stars is researched by studying the light they emit and their motions in relation to other stars. And the courses they take to do this is Physics, Mathematics, and astronomy (that's an actual course). Colleges have actual degrees in astronomy and you can look at the college and see what their student course book says for that particle college. Good luck if this is what your pursuing.

∙ 8y agoAn astronomer studies mathematics, physics, and philosophy. That's what Galileo Galilei studied and he was an astronomer. The answer to that question is the scientific study of celestial objects (such as stars, planets, comets, and galaxies
Celestial objects like: planets, stars, comets, novas...etc.

∙ 15y agothey go to space and see them Oh there are many different ways that they use to study the stars... mainly with telescopes though. And of course now&then they'll send send people into space to study planets first hand. They'll collect dust, and rock, and take lots of pictures to bring back to earth with them. =) It's all realy interesting actualy, what people will do in order to further education for their children and future generations! Hope I was able to help

∙ 6y agoAstronomers use telescopes to view things in space. Telescopes are optical, infrared, and gamma ray. On the ground they use radio telescopes to view things in space. Some telescopes are launched into space such as the Hubble Telescope.

How did you find stars?
look in the sky at night. The clearer the sky the more stars you see. Go to the country side and in a clear night there are lots and lots of stars!
Does big dipper move through the night sky?
Yes because stars move so they would move through the night sky!!!! If you were to watch a constellation, it would appear to move through the sky but really the Earth's rotation and revolution about the Sun gives the appearance of the stars moving.
What is a constellation to modern astronomers?
just a specific region in the sky
How do you see stars at night?
just look outsie the window up at the sky.
How many constellations are recognized by astronomers today?
There are 88 constellations recognized by astronomers right now.
Which forms of electromagnetic radiation can interfere with the work of astronomers?
Light. In the form of light pollution in the night sky.
Who were the first astronomers in the world?
Many people consider the first astronomers to be the first humans that ever looked up at the night sky and wondered what was really up there. So cavemen were probably the first astronomers.
If Galileo used a telescope to investigate the night sky why did his fellow astronomers not use a telescope also?
this is one of my questions for homework
What tool do you think helped astronomers study the sky is the most?
The telescope helps astronomers the most when studying the sky.
Do astronomers divide the sky into galaxies?
no, they divide the sky into constellations
Would you be able to see the hyper nova of eta carinae?
It is not visible in the night sky, but you can look through a telescope. Depends on what kind.
How do you find constellations?
you look in the sky on a clear night
What is the number of stars vin the universe?
Currently there are estimated 400 billion stars according to astronomers, althrugh not all are visible in the night sky.
Why couldn't early astronomers tell the difference between single stars and the entire galaxies when the looked at the night sky?
Unless you have a extremely powerful telescope, a galaxy and a star look almost the same.
How do you think the milky way got its name?
The Milky Way was named when the early astronomers looked up at the night sky and saw a milky band of dim stars going across the sky.
What does the Astronomers use to observe the sky?
a stethoscope
Is there a lot of light pollution on Earth that makes it difficult for astronomers to observe at distant stars?
Yes, human electric lighting is polluting the night sky.
