What is astronomical unit, light year and parsec?
Another name for the intersteller gas and dust that will eventually become a star.
What is a nebula?
The outermost layer of the Sun's atmopshere.
What is the Corona?
What is they are cooler?
The source of the Sun's energy.
What is Nuclear Fusion?
Steller distances are usually measured in this unit.
What is light years?
A A star is said to be born at this stage.
What is a protostar?
The center of the Sun is believed to be this.
What is a solid core?
Stars of this temperature have the highest surface temperature.
What is blue?
The apparent shift in a star's appearance taken in the Winter and Summer.
What is parallax?
The force most responsible for the formation of a star.
What is gravity?
The next stage in the Sun's life cycle.
What is a red giant?

What is mass?
Elements are spread throughout the universe during this.
What is a supernova explosion?

What is a black hole?
90 % of stars on the HR diagram are in this group, just like our Sun.
What is main sequence?
Resistance to being squeezed close together creates a pressure that halts the collapse of the core. Also the last stage for a large mass star.
What is a Neutron Star?
All stars, regardless of size, eventually do this.
