Where do stars begin?

Answer 1

They all begin as protostars.

They begin as large amounts of gas and dust that slowly swirl around and combine, then they start getting REAL hot as intense light mercilessly bombards them and then begins their reign as a star.

Answer 2

Stars begin as a nebula, a cloud of gas and dust. As the nebula begins to contract or condense, it heats up and starts to burn. Usually, the first stage is a "main sequence" star which is fueled by the process of nuclear fusion of hydrogen into helium. Depending on the mass of the star, the star will take a different path in it's life cycle. Just as an example, our Sun is a main sequence star.

Answer 3

The stars are born when much ore gas are contracting in a particular point in the universe. at that tie surrounding gases are spreaded in every side of stars . all their combination of clusters are called as nebula.

Answer 4

stars begin their life cycles in a nebula.
Stars are born when new stars form from large , cold clouds of dust and gas (mostly hydrogen that lie between existing stars in a galaxy). Stars usually start to form in a Nebula a cloud of interstellar hydrogen gas and dust. When the gas and dust are forced together, they form a slowly rotating globule. Gravitational forces survives through gas pressure and the globule starts to collapse, then the cooling occurs and the spin increases. The globule starts to change into a protoplanetary disk (which could also become planets) and in the central core (which will become a star). The core of the Protoplantary Disk starts to increase in temperature. When fusion starts to begin, that's when a Protostar has been formed. If the temperature reaches about 27,000,000,000°F, Nuclear Fusion begins, then stars starts to form. When stars are born they come in different sizes and their color range from blue to red. The size of a star depends on the gas and dust that have been collected during the birth of the star. The color of the star depends on the surface temperature of the star. The more mass a star starts out with the hotter and brighter it will be.

Answer 5

A nebula is a large cloud of gas. Stars are also made of gas (mostly hydrogen). When a cloud of gas contracts into a smaller volume because of it own gravitational attraction for itself, if there is enough of it the result will be a star.

Answer 6

A star begins as a large mass of hydrogen and helium atoms. Large quantities of hydrogen and helium atoms are found in nebula which are like star nurseries. As the atoms bump into each other and are pulled together by gravity it produces heat and nuclear fusion begins. That is what causes the sun to be hot and produce heat. When the nuclear fusion in the sun stops the sun will disappear. I recommend reading a book on the life of a star because it is very fascinating.

Answer 7

A nebula is a collection of gas and dust that can stretch for several light years. And is probably how out solar system began.

A star can be "born" inside a nebula when the explosion of a nearby star or some other force causes a disturbance to the nebula. This in turn causes some gas particles and dust particles to begin joining together through the force of gravitational attraction. Bigger particle attract smaller ones.

Eventually, the cloud of gas will begin rotating around a single area, the area with the highest mass, attracting more and more gas towards it.

Over time, this rotating cloud will become a protostar, and the gas will begin to glow due to the high temperatures being produced the the mass of the protostar.

Over even more time the protostar will become so massive that the temperature and pressure within the protostar's core begins forcing hydrogen atoms to fuse together into helium. The moment the first 2 hydrogen atoms fuse together, a star is born.

Answer 8

Yes, they do. All of them do, but each one ends their life in a different way.

Answer 9

there is no way that you can form a nebula

Answer 10

A star is born when the contracting gas and dust from a nebula becomes so dense and hot that nuclear fusion starts. And is trumpf a ______?
