What stage comes after nebula in the star stage?
The stage that comes after the nebula in the star's life cycle is the protostar stage. During this stage, gravity causes the gas and dust within the nebula to clump together and heat up, eventually forming a dense, hot core. This marks the beginning of nuclear fusion within the protostar.
Why did the nebula begin to shrink inward?
The nebula began to shrink inward due to gravitational forces. As particles within the nebula were pulled toward its center, the concentration of mass increased, leading to the formation of a protostar at the core. This marks the initial stage of a star's formation.
How are nebulae and stars related?
Nebulae are large clouds of dust and gas in space where stars are born. Within a nebula, gravitational forces can cause the gas and dust to collapse and form a protostar, which eventually ignites nuclear fusion and becomes a star. Therefore, nebulae are the birthplaces of stars, and stars are formed from the material within nebulae.
What are the two main restroing forces for tides?
The two main restoring forces for tides are gravitational forces from the Moon and the Sun. These forces create bulges in the Earth's oceans, causing high and low tides as the Earth rotates within this gravitational field.
What is the beginning stage in the formation of a star called?
The beginning stage in the formation of a star is called a protostar. This is when a dense core within a molecular cloud begins to accumulate gas and dust, causing it to heat up and eventually become a star.
Why doesnt a protostar form a black hole?
The pressure within a protostar counters gravity and prevents the star from collapsing further.
What is a binary protostar?
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
What happens when matter is pulled into a protostar?
When matter is pulled into a protostar, it heats up and increases in density. This process leads to the formation of a protostar as gravitational forces pull matter towards the center, eventually igniting nuclear fusion and forming a stable star.
When does the protostar become balanced?
A protostar becomes balanced when the gravitational forces pulling matter inward are balanced by the outward pressure due to nuclear fusion at its core. This marks the transition from a contracting protostar to a stable star in the main sequence phase of its lifecycle.
What stage comes after nebula in the star stage?
The stage that comes after the nebula in the star's life cycle is the protostar stage. During this stage, gravity causes the gas and dust within the nebula to clump together and heat up, eventually forming a dense, hot core. This marks the beginning of nuclear fusion within the protostar.
What is the process by which a protostar is heated up to initiate nuclear fusion and become a star?
A protostar is heated up by gravitational forces causing it to contract and increase in temperature. Once the core reaches a high enough temperature and pressure, nuclear fusion reactions begin, releasing energy and making the protostar shine as a star.
What does the word strongmen means?
The strong men are the two forces within.
Why did the nebula begin to shrink inward?
The nebula began to shrink inward due to gravitational forces. As particles within the nebula were pulled toward its center, the concentration of mass increased, leading to the formation of a protostar at the core. This marks the initial stage of a star's formation.
The earliest stage of a stars life is called a?
A Protostar.

The two main restoring forces for tides are gravitational forces from the Moon and the Sun. These forces create bulges in the Earth's oceans, causing high and low tides as the Earth rotates within this gravitational field.
What is the difference between a nebula and a protostar?
A nebula is a vast cloud of gas and dust in space, while a protostar is a dense region within a nebula where gravity causes material to come together and heat up, eventually leading to the formation of a star. In essence, a protostar is a stage in the formation process of a star within a nebula.
