Doing this project I learned the following things:
- Many of the objects in the sky that I have analyzed are made of hydrogen, oxygen and carbon.
- There are some stars that can change their luminosity over time.
- You can get your own formulas with excel. As we did with the ceceid graph. From the data on the website that the teacher told us we were able to get a graph and from this graph and from this graph we were able to get a general formula.
- From a simple graph you can extract a lot of information and make calculations with it.
- The stars can move and over time they can return to their original place.
- To deduce what element it is through its energy.
- The radius of a star or a planet can be calculated.
- They are a lot of differents objects in the sky and you can analyze them with certain programs or formula.
- Hydrogen is the most abundant chemical element, constituting approximately 75% of the visible matter in the universe. In their main sequence, stars are mainly composed of hydrogen in the plasma state.
(In some spectrum analyzes letters come out instead of numbers because I didn't notice)
