Stage 1- Stars are born in a region ofhigh density Nebula, and condenses into a huge globule of gas anddust and contracts under its own gravity. This image shows theOrion Nebula or M42 . Stage 2 - A region of condensingmatter will begin to heat up and start to glow formingProtostars..
Also to know is, what are the stages of a star?
7 Main Stages of a Star
- A Giant Gas Cloud. A star begins life as a large cloud ofgas.
- A Protostar Is a Baby Star.
- The T-Tauri Phase.
- Main Sequence Stars.
- Expansion into Red Giant.
- Fusion of Heavier Elements.
- Supernovae and Planetary Nebulae.
Also, what is the main sequence of a star? Definition of a Main Sequence Star A main sequence star is any star that isfusing hydrogen in its core and has a stable balance of outwardpressure from core nuclear fusion and gravitational forces pushinginward.
Besides, how are stars formed step by step?
The birth of stars Stars are born when pockets of gas and dustwithin interstellar molecular clouds exceed critical density andcollapse under their own gravity. Once the pressure and thetemperature inside get high enough for nuclear fusion to ignite, itcreates a star.
What is the birth of a star called?
All stars are born from collapsing clouds of gasand dust, often called nebulae or molecular clouds. Over thecourse of millions of years, these protostars settle down into astate of equilibrium, becoming what is known as a main-sequencestar. Nuclear fusion powers a star for most of itslife.

What stage of life is our sun in?
All stars die, and eventually — in about 5 billionyears — our sun will, too. Once its supply of hydrogenis exhausted, the final, dramatic stages of itslife will unfold, as our host star expands to becomea red giant and then tears its body to pieces to condenseinto a white dwarf.How long is a stars life?
Stars live different lengths of time, dependingon how big they are. A star like our sun livesfor about 10 billion years, while a star which weighs 20times as much lives only 10 million years, about athousandth as long. Stars begin their lives asdense clouds of gas and dust.What does a star become when it dies?
Stars Like the Sun When the core runs out of hydrogen fuel, it willcontract under the weight of gravity. The upper layers will expandand eject material that will collect around the dying starto form a planetary nebula. Finally, the core will cool into awhite dwarf and then eventually into a blackdwarf.How do stars die?
Stars die because they exhaust their nuclearfuel. Really massive stars use up their hydrogen fuelquickly, but are hot enough to fuse heavier elements such as heliumand carbon. Once there is no fuel left, the star collapses and theouter layers explode as a 'supernova'.What is a newborn star called?
Star birth. Like people, stars are born,they grow old and they die. Their birth places are huge, coldclouds of gas and dust, known as 'nebulas'. The most famousof these is the Orion nebula, which is just visible with theunaided eye.Which color are the hottest stars?
blue
Why do most stars not necessarily die?
The reason why stars does not die when itis there time is because they tend to fuse indifferent and more heavier elements.Do stars move?
The stars are much much much farther away thanany distance you can move on the Earth, so you shouldn't beable to see them "move" on the sky just by moving onthe Earth. One thing to keep in mind, however, is that the starsdo move slowly over the course of the night.How long do stars take to form?
10 million years
What is a star made of?
Stars are made of very hot gas. This gas ismostly hydrogen and helium, which are the two lightest elements.Stars shine by burning hydrogen into helium in their cores, andlater in their lives create heavier elements.What causes a star to form?
Star Formation. Stars form insiderelatively dense concentrations of interstellar gas and dust knownas molecular clouds. These regions are extremely cold (temperatureabout 10 to 20K, just above absolute zero). Star formationbegins when the denser parts of the cloud core collapse under theirown weight/gravity.Why do stars twinkle?
Stars twinkle because of turbulence in theatmosphere of the Earth. As the atmosphere churns, the light fromthe star is refracted in different directions. This causes thestar's image to change slightly in brightness and position, hence"twinkle."What element is the fuel for main sequence stars?
hydrogen
Why is a main sequence star stable?
Main sequence star During this stable phase in the life of astar, the force of gravity holding the star togetheris balanced by higher pressure due to the high temperatures. TheSun is at this stable phase in its life.How are stars classified on an HR diagram?
The Hertzsprung-Russell Diagram is a graphicaltool that astronomers use to classify stars according totheir luminosity, spectral type, color, temperature andevolutionary stage. Stars in the stable phase of hydrogenburning lie along the Main Sequence according to theirmass.What stars are produced during a supernova event?
A supernova can light the sky up for weeks, andthe massive transfer of matter and energy leaves behind a verydifferent star. Typically only a tiny core of neutrons, aspinning neutron star, is left to evidence asupernova. Neutron stars give off radio waves in asteady stream or, as pulsars, in intermittent bursts.Can the life cycle of a star be studied directly?
Basically, it is very difficult to pin down anindividual star's age. It has taken astronomers most of thiscentury to piece together the life cycles of stars,simply because we cannot live long enough to follow a singlestar through its life cycle.What is a pulsar star?
A pulsar (from pulse and -ar as in quasar) is ahighly magnetized rotating neutron star or white dwarf thatemits a beam of electromagnetic radiation. Neutron stars arevery dense, and have short, regular rotationalperiods.
