Stars
The property of stars that scientists use to determine the temperature of a star.
What is color?
Nebula, then protostar, main sequence, giant, and then finally white dwarf
What are the stages of a low mass star?
Huge, arching columns of gas between the magnetic field of sunspots on the Sun.
What is a prominence?
A type of galaxy with new stars.
What is spiral galaxy?
Two main features of the universe.
What are star systems and galaxies?
The method used to measure the distance of stars close to Earth by viewing the star from Earth's location at one time during the year and then six months later.
What is parallax?
This stage occurs when the core of a star has fused all of its hydrogen into helium.
What is a giant?
The layer of the sun next to the core.
What is the radiation zone?
A type of galaxy with older stars.
What is elliptical galaxy?
This is used to determine the motion of stars and galaxies.
What is the Doppler effect?
The most common elements in which stars are composed of.
What are hydrogen and helium?
The one factor that determines the outcome of a star's life cycle.
What is starting mass?
Temporary regions in the Sun's surface that are cool.
What are sunspots?
This is the type of star system and galaxy in which our star belongs.
What is a single star system and a spiral galaxy?
The apparent change in the wavelength of a moving object.
What is the Doppler effect?
This is determined by the size and temperature of a star.
What is absolute magnitude?
The joining of two nuclei of hydrogen atoms to form helium with extreme amounts of energy being released.
What is nuclear fusion?
The layer of the Sun next to the corona.
What is the chromosphere?
This is the amount of stars a galaxy can hold.
What are billions and billions of stars?
An explanation that states all matter and energy exploded from one point and has been expanding apart ever since.
What is the big bang theory?
The unit used to measure the distance between stars.
What is a light year?
As absolute magnitude increases in a star so does its surface temperature.
What is relationship shown on the H-R diagram for main sequence stars?
This gathers around sunspots which will cause flares.
What is gas?
The shift that shows the compaction, or shortening, of wavelengths by the spectroscope.
What is blue shift?
Evidence that supports the big bang theory.
What is the red shift of all stars and galaxies in our universe?
