A nebula is a cloud-like object composed of gas and dust in interstellar space. The density of matter in a nebula is very low. If measured by the standards of the earth, some places are a vacuum. But the accumulation of nebulae is very large. Nebulae and stars have a "blood relationship". The gas emitted by the stars will become part of the nebula, and the nebula material will be compressed into stars under the influence of gravity. Under certain conditions, nebulae and stars can be transformed into each other. of. What does the following statement match this text?
