Simply complicated: Planetary Nebula



Stars can be classified into two types: Type I stars, enriched in heavy metals. Type II stars containing a minimum amount of metals.

There are two techniques for detecting metals in a nebula, but neither is accurate. When examined, both methods can show different indications. Therefore, scientists suggest that the planetary nebula contains cold clumps of matter.


Planetary Nebula – The gas that forms around a star is a planetary nebula. This is a fast process compared to astronomical yardsticks.

Photos were taken using a telescope. These photographs were used to study the structure and envelope of stars.

There are two types of symmetric nebula: fast and slow stellar winds. The nebula is the last stage in the development of a star before its further transformation.

The color of the nebula varies from blue to burgundy (in particular, it all depends on the size and structure of the star and its shell). Small stars, due to the slow burning of hydrogen, will last longer.

Naturally, the larger the star, the less it lives due to the rate of hydrogen combustion. The combustion of substances holds the star by gravity.

Over time, the supply of hydrogen will dry up, the core will begin to shrink and heat up. The outer layers will cool and grow in size. This is the process of transformation of the Sun into a red giant…
