NGC2327

WHAT IS A NEBULA?

A nebula is a giant cloud of dust and gas in space. Some nebulae come from a gas and dust ejected by the explosion of dying star, such as a supernova. Other nebulae are regions where new stars begin to from. For this reason, some nebulae are called "star nurseries".

HOW DO STARS FROM IN A NEBULA?

Nebulae are made of dust and gases. The dust and gases in a nebula are widely dispersed, but gravity can begin to pull together groups odf dust and gas. As these groups get bigger and bigger, their gravitational pull gets stronger and stronger.

Eventually, the group of dust and gases becomes so large that it collapses under  its own gravity. The collapse causes the material in the center of the cloud to heat up, and this hot core is the beginning of a star.

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: 3158 mm²/ 94491 mm² · 100 = 3,34 %  (O) Oxygen

-PEAK 2: 3624 mm²/ 94491 mm² · 100 = 3,83 %  (O) Oxygen

-PEAK 3: 12730 mm² / 94491 mm² · 100 = 13,47 %  (H) Hydrogen

-PEAK 4: 5775 mm² / 94491 mm² · 100 = 6, 11%  (Ge) Germanium

TOTAL AREA: 94491 mm²

^{(O) Oxygen: 7,17 %}

^{(H) Hydrogen: 13,47 %}

^{(Ge) Germanium: 6,11 %}

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