A star begins its life as a cloud of dust and gas (mainly hydrogen) known as a nebula. Explanation: A prostate is formed when gravity causes the dust and gas of a nebula to clump together in a process called accretion. ... If a critical temperature in the core of a prostate is reached, then nuclear fusion begins and a star is born
