Get Life Cycle Of A Star Worksheet Answers

Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.

Summary. A star begins its life in a nebula, struggles to balance gravitational pull and internal pressure during its main sequence period, and ends its life in an explosion to eventually become a white or black dwarf, or a neutron star, or a black hole.

Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.

There's a lot to know about the life cycle of a star. From nebula to protostar, through the main sequence to red giant before ending as a white dwarf, neutron star, or black hole, our stellar neighbors lead amazing lives.

A star begins its life in a nebula, or area of gas and dust in space. The gas and dust come together to form a protostar, which gets very hot until it turns into a main sequence star. This stage is when nuclear reactions occur and the star glows, and it can last billions of years.

All stars will expand, cool and change colour to become a red giant. What happens next depends on how massive the star is. A smaller star, like the Sun, will gradually cool down and stop glowing. During these changes it will go through the planetary nebula phase, and white dwarf phase.

This cloud collapses under its own gravity to form a protostar, which then continues to contract and heat up until it becomes a main sequence star. After it has used up most of its fuel, a star may expand into a red giant and then eventually collapse to form a white dwarf.
