Apr 16, 2018 · Heavy stars turn into supernovae, neutron stars and black holes whereas average stars like the sun end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, however, follow roughly the same basic seven-stage life cycle, starting as a gas cloud and ending as a star remnant.
Star Stage is a half-hour American television anthology series that began on September 9, 1955, and ended on September 7, 1956.

Part of: Stars. Life Cycle of Stars. Star Formation. Star Death. Stellar Evolution. Black Holes. All stars form in nebulae, which are huge clouds of gas and dust. Though they shine for many thousands, and even millions of years, stars do not last forever.
Webb is addressing several key questions to help us unravel the story of the star and planet formation: How do clouds of gas and dust collapse to form stars? Why do most stars form in groups?
Our Sun is roughly midway through its main sequence stage. A star’s gas provides its fuel, and its mass determines how rapidly it runs through its supply, with lower-mass stars burning longer, dimmer, and cooler than very massive stars.
Jan 15, 2023 · Stage 1: A Giant Cloud of Gas. Above: The Helix Nebula, located 700 lightyears away from Earth. Image Credit: NASA. Stars begin their life cycles as clouds of gas and dust within a vast expanse of stellar debris called a nebula, formed from the gas and dust expelled by the explosion of a dying massive star.
Star formation and evolution. stellar evolution. Throughout the Milky Way Galaxy (and even near the Sun itself), astronomers have discovered stars that are well evolved or even approaching extinction, or both, as well as occasional stars that must be very young or still in the process of formation. Evolutionary effects on these stars are not ...
