NGC2295

WHAT IS A GALAXY?

A galaxy is grouping of stars, celestial bodies and cosmic matter that is concentrated in certain region of space by the effect of gravitational attraction and constitutes a unit in the universe.

HOW IS GALAXY FORMED?

According to the first galaxies were formed by the collapse of vast clouds of gas and dust due to their own force of gravity, allowing stars to form.

This is its energy spectrum from JS9 with its most importants energy peaks.

Then, I have calculated each peak's percentatge and find out which elements they contain.

I have used this formula:

-PEAK 1: 2446 mm²/ 84740 mm² · 100 = 2,89 %  (C) Carbon

-PEAK 2: 2891 mm²/ 84740 mm² · 100 = 3,41 %  (O) Oxygen

-PEAK 3: 13265 mm² / 84740 mm² · 100 = 7,68 %  (Cr) Chromium

-PEAK 4: 4437 mm² / 84740 mm² · 100 = 6, 11%  (Eu) Europium

TOTAL AREA: 84740 mm²

^{(C) Carbon: 2,89 %}

^{(O) Oxygen: 3,41%}

^{(Cr) Chromium: 7,68%}

^{(Eu) Europium: 6,11%}

With the help of this website I was able to find out what element each peak corresponds to:

^CARBON

^OXYGEN

^.

^CHROMIUM

^EUROPIUM

^{I have assumed that these peaks are the elements that I have indicated, but it may be that they aren't these and that it is incorrect because, in this case, the electrons jump from layer 3 to layer 2 and this means that the temperature has to be similar environmental, and therefore is low. But if we increase the layers, the electron volts go up, and for this reason it may be that my analysis is incorrect.}
