Stars
The property of stars that scientists use to determine the temperature of a star.
What is color?
What are the layers of a star beginning with the core?
Core, radiation zone, convection zone, photosphere, chromosphere, corona
What element does the sun use to create energy?
Hydrogen
A type of galaxy with new stars and arms like a windmill
What is spiral galaxy?
The brightness of a star as seen from Earth
What is apparent brightness?
This stage occurs when the core of a star has fused all of its hydrogen into helium. (Hint: What will the sun become?)
What is a giant?
The layer of the sun next to the core.
What is the radiation zone?
What gives a planet it's spherical shape?
gravity
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?
What element is created when hydrogen is fused?
Helium
Giant space snowballs. (ice, dust, gas orbiting the sun)
What is a comet?
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?
A giant object made of rock and iron
what is an asteroid?
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 shows us this relationship?
