What is the first stage of star creation?

Answer 1

A star's first life stage is called a protostar. The formation starts in a region of space with accumulated gas and dust, called a nebula. The attraction of gravity between the atoms of gas and grains of dust causes a small area of this nebula to collapse into a smaller, rotating cloud of dust and gas. More material is then drawn in, and the mass at its core increases and the temperature climbs. If the core gets hot enough, it will begin to glow. That is the protostar.

Answer 2

All stars are started from the gas of a nebula, which condenses and forms a protostar. As the star ages it expands and the core turns hydrogen into helium in a process of fusion. Once the hydrogen and then the helium runs out the star cools and becomes less bright.

Answer 3

It starts as a nebulathat's a cloud of dust and gas.

Then the nebula starts to clump together and spin.

Then that makes a protostar.

Once it hit hits 15 million degrees celsius then nuclear reactions start and it becomes a star!!!!!!!!!!!!!!!!!!!!!!!!!!! :O) ;O)

Answer 4

A PROTOSTAR is the 1st stage of the formation of a star.

Comment : But you could say that the nebula of gas and dust from which the protostar forms is actually the first stage. In that case, the answer is a "nebula".

Answer 5

Turbulence deep within giant clouds of gas in space gives rise to knots with so much mass that the gas and dust can begin to collapse under its own gravitational attraction. The material at the center begins to heat up and will one day become a star.

A star needs to form from a nebula, or a giant cloud of hydrogen gas. There are nebulae scattered throughout our galaxy and they are often called "stellar nursuries" because they give rise to stars.

Often, radiation from a nearby supernova will trigger the formation of stars within the region by causing the clouds of gas to begin to contract. The gases will collect in the center and begin to heat up from friction, forming a protostar.

For a true star to form it needs to begin the process of nuclear fusion. Eventually the protostar will get hot enough for hydrogen to begin fusing into helium, releasing large amounts of heat and light, among other forms of radiation. And so, a star is born.

This entire process is slow and usually happens over long periods spanning millions of years.

Answer 6

star born in molecular cloud, and core is what we called protostar,they start to balance size and star were born.

Answer 7

Mainly they have to have a sufficient mass; that way they will have the necessary amount of temperature and pressure for nuclear fusion.

Answer 8

Protostar.

Comment: Or, perhaps it's the nebula from which the protostar forms.

Answer 9

A star is composed of three elements;

1. Hydrogen

2. Time

3. Gravity

Given enough of each, you'll get stars.

Answer 10

A "protostar" forms, from a "nebula" of gas and dust.
