WebThe birth of a star begins when massive clouds of dust and gas start to collapse and break down. How does this happen. It happens through the force of gravity. Gravity bounds the … WebA star is formed from a nebulae, which is a cloud of dust and gas. The dust and gas particles are drawn together by the gravitational attraction between them. As the nebulae contracts, the dust and gas particles lose gravitational potential energy and gain kinetic energy, and a hot, dense region forms. This hot, dense region (known as a ...
WebTypes of Stars. NASA’s Solar Dynamics Observatory captured this image of our 4.6-billion-year-old Sun, a main sequence star. Scientists expect it will remain one for another 5 billion years before becoming a red giant. Credit: NASA's Scientific Visualization Studio/SDO. The universe’s stars range in brightness, size, color, and behavior. WebStars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. The outflow of energy from the central regions of the star provides the pressure necessary to …
A protostellar cloud will continue to collapse as long as the gravitational binding energy can be eliminated. This excess energy is primarily lost through radiation. However, the collapsing cloud will eventually become opaque to its own radiation, and the energy must be removed through some other means. The dust within the cloud becomes heated to temperatures of 60–100 K, and thes…
