Arisa asking Rose something
What are you thinking about Rose??
To put in simple terms the star has a life cycle and it starts off as a nebula. A nebula is a made up of gas and dust.
Rose tells Arisa about the first stage in a star's life.
Well I am thinking about how a star has the same life cycle as us....A star first is born or made into the world or first a nebuela.
Hmm interesting
When the star becomes large and a red gaint. This giant is now a dying star in its final stage of steller evolution.
That is when the star has burning hydrogen at its core.Continuing on the third stage of the star is when tht star becomes a red giant and it is now halfway through its life cycle.
Rose explains the 2nd and 3rd stages of a star's life. Arisa gains interest
Continuing on with the 2nd and 3rd stage the 2nd stage. Is when the nebula is a star and that stage is called Main sequence star.
Wow, amazing!
Next is the Planetary Nebula. This is the 4th stage. What this is a ring shaped nebula formed by an expanding shell of gas surrounding the aging star.
When Arisa is amazed at the life cycle, Rose continues...
This is so fascinating Rose I have learned so much!! Can't wait to learn more!
Rose moves onto the 5th stage and Arisa is still amazed.
Ok now onto the 5th stage, this one is a White dwarf.A white dwarf is star that is burned up and all the hydrogen is used all up,
Wow...
The final stage is called the black dwarf. And a black dwarf is a very small cooled remnent of a white dwarf that has no light projecting from it.
The life of the star is ending and Arisa's interested grows.
Of course Arisa
Hmm that is quite intersting Rose thank you for thank you for telling me about the life cycle.
