<p>I have completely no idea about astronomy, but I am starting growing interest in it as I have been always wondering on what has been discovered out there and since I am studying CS, maybe I will learn more than I think as CS and astronomy as relative to some point. How should I start? Can you suggest me a good website for example or something else?</p>

It can be fun to write code that does simple astronomical calculations. But to do high quality 
accurate programs takes a lot of work and knowledge. Fortunately, there are great free astronomy software libraries available, so you don't have to write everything from scratch, but you still need to understand what you're doing. ;)

If you are young, you can start some astronomy study beside the CS. The astronomy worths much more, even if it is not a monetary worth. You will see it.

IMHO, a good starting point for someone who's doing computer science who wants to combine it with astronomy is to learn about the different kinds of time used in astronomy and how they're related to one another. Eg, sidereal time, mean solar time vs apparent solar time, etc. Also start learning about the celestial sphere and the various astronomical coordinate systems. True, this material can be a bit dry, and sometimes confusing, but you need a solid foundation if you want to get into astronomical computing.

I'm not up on all the ins and outs, but can this be moved to meta rather than closed, or is there some sub-section where this can go?   I hate to see a sincere question that people obviously want to answer, closed because it's not pure astronomy, though this one has answers, so a close wouldn't be so bad, but I think finding another area for questions like this would be better.

@ΚωνσταντίνοςΚορναράκης the tag would still be outside mainstream astronomy, but maybe a sub-group.   Something along those lines.   Just putting the idea out there.   (and don't feel bad if this gets closed, questions like this usually get closed).

To me it sounds that you just want to expand your astronomical knowledge and are not actually looking for a career advice.

I would suggest to just start with reading popular science books.
<https://en.wikipedia.org/wiki/Cosmic_Evolution_(book)> ,
<https://en.wikipedia.org/wiki/A_Brief_History_of_Time> for example.

Understanding how things work out in space is only half the fun;
the other half is seeing them with your own eyes.
Field guides by
[Pasachoff](http://web.williams.edu/Astronomy/fieldguide/)
and others can help bring the two together.
Magazines like [Sky & Telescope](http://www.skyandtelescope.com/)
offer information about temporarily observable objects like comets
and cover science news at level between mass media and academic journals.

Hands-on observing experience can motivate programming projects in ways that textbooks can't.
Given the free availability of such good software as [Stellarium](http://stellarium.org/) and [JPL HORIZONS](https://ssd.jpl.nasa.gov/horizons.cgi),
and libraries like [Astropy](http://www.astropy.org/),
it's wise not to spend much time reinventing wheels.
On the other hand, implementing a few things yourself will expose you to various astronomy, math, algorithm, and data structure issues.
You can always check your work against off-the-shelf tools, or better yet, against the real sky.

If you want to know about stars, i.e., astronomy or astrophysics, [Caroll & Ostlie](https://rads.stackoverflow.com/amzn/click/0805304029) is somewhat fundamental textbook for undergrad & grad.

If you want to know about galaxy and universe, i.e., cosmology, we use the textbook from [Ryden](http://carina.fcaglp.unlp.edu.ar/extragalactica/Bibliografia/Ryden_IntroCosmo.pdf).

My recommendation is to understand stars first, before you deal with galaxy, and then universe.
