Final answer:
Stars are formed from huge, cool dust and gas clouds in the Milky Way galaxy. These clouds undergo gravitational collapse and nuclear fusion, leading to the formation of stars.
Step-by-step explanation:
Stars are formed from huge, cool dust and gas clouds that are found in the Milky Way galaxy. These dense and cold clouds of gas and dust are the raw materials from which stars are assembled. Since stars are made of gas, astronomers focus their attention and telescopes on these gas clouds to find stars in the process of formation.
These gas clouds are seen in close-up images of nebulae like the Carina Nebula, where the energy from newly forming stars is revealed. The gas and dust within these clouds come together under gravity and undergo a process called gravitational collapse. As the cloud collapses, it begins to heat up until the pressure and temperature at the center are high enough for nuclear fusion to start, leading to the formation of a star.
Therefore, the correct answer is C) huge, cool dust and gas clouds.
