Section One, Part One Molecular clouds(Very large clouds of gas and dust tens of times larger than our solar system) run amuck in space. Inside, larger particles of dust attract smaller ones, because they have a stronger gravitational pull. These larger particles continued to gain mass. As one solid mass, now known as a protostar, is around 10 to 20 Kelvins. To become a star, the protostar must reach 15,000,000°. Until the mass reaches 15,000,000°, it will remain a protostar. Section One, Part

Despite these occurrences, such as deaths within his family, starvation, and inflation, Heberle and his family were apart of the very few survivors of
