No. Stars are born when nebulae collapse, not when they expand.
The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).
It is called a nebula.
None at all/ The life cycle of a star is based on it's initial mass, not where it was formed.
A star like our sun will shed a planetary nebula after its 'death'
No. Stars are born when nebulae collapse, not when they expand.
The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).
The star's atmosphere that expands a million times is called the planetary nebula. It is able to expand between 200 to 800 times the radius of the sun.
It is called a nebula.
a nebula is cloud of particles which forms into a star.
A nebula may condense and ignite to become a star, conversely a star may explode and form a nebula.
A star is "born" in a large cloud of dust and gas called a nebula
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
It is called a Nebula (nebulae for plural). no sorry but your wrong it is a coma It can be both it just depends. The question needs to be more specific
None at all/ The life cycle of a star is based on it's initial mass, not where it was formed.
A White Dwarf Star remains.
A Nebula is a gas of dust and minerals that surrounds a star. Also, a nebula is a birthplace of a star, where a star and sometimes a solar system is formed after a huge explosions
