Stellar astronomy is the study ofstars, including their creation, evolution, and deaths. Astronomers observe these objects across all wavelengths and apply the information to create physical models of the stars. Galactic astronomy focuses on the objects and processes at work in the Milky Way Galaxy....

How does a star do this "stellar nucleosynthesis" and not blow itself apart in the process? The answer: hydrostatic equilibrium. That means gravity of the star's mass (which pulls the gases inward) is balanced by the outward pressure of the heat and light—theradiationpressure—created by th...
The biggest known star is UY Scuti, about 1,700 times larger than the sun.(Image credit: Philip Park (CC BY-SA 3.0)) However, all stellar sizes are estimates. "The complication with stars is that they have diffuse edges," astronomer Jillian Scudder of the University of Sussex wrote for...
