High Mass Stars. High mass stars have a mass greater than 3 solar masses. They are extremely hot and glow blue and white.
Apr 16, 2018 · The T-Tauri Phase. In the T-Tauri stage, a young star begins to produce strong winds, which push away the surrounding gas and molecules. This allows the forming star to become visible for the first time. Scientists can spot a star in the T-Tauri stage without the help infrared or radio waves. Advertisement.
A hundred years ago, scientists did not know that stars are powered by nuclear fusion, and 50 years ago they did not know that stars are continually forming in the Universe. Researchers still do not know the details of how clouds of gas and dust collapse to form stars, or why most stars form in groups, or exactly how planetary systems form.
Sep 26, 2022 · Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from ...

The life cycle of a star is the process of change that every star undergoes over time. It begins when a molecular cloud collapses under its own gravity and begins to contract, heat up, and break up into smaller fragments that give birth to the young star. It ends when the star becomes a stellar remnant: a white dwarf, neutron star, or black ...

Stars populate the universe with elements through their “lifecycle”—an ongoing process of formation, burning fuel, and dispersal of material when all the fuel is used up. Different stars take different paths, however, depending on how much matter they contain—their mass. A star’s mass depends on how much hydrogen gas is brought ...
