Their nuclear energy supplies have been used up and this is the last stage in the life cycle. 位置 詞語 Massive Star 定義 These are the brightest stars that form from a nebula. They are white or blue in color. They have masses 100 times that of the Sun but they live for less than...
Some stars are very big, and they have short, spectacular lives, while others are so small that they barely had enough mass to become a star in the first place, and these have extremely long lives. The life cycle of a star, is highly dependent on mass. We touch on the classification ...
Life Cycle Of A Star gas that makes up the nebula is hydrogen. Sometimes nebulas can remain mostly static for billions of years. Eventually though a passingstaror shock wave from a supernova will disturb the gas and dust. The dust and gas may then start to clump together‚ gravity will...

The life cycle of a star begins as a large gas cloud. Also, the temperature inside the cloud is low enough that a molecule can form in it. It is a baby star that forms when gas particles in the molecular cloud run into each other, and they create heat en
