This is a recognizable pattern that is made by a group of stars within the night sky.
What is a constellation?
100
When the sun gets older, it will expand and cool to become this type of very large, bright star.
What is a red giant?
100
Young stars form within a cloud of dust and gas that is called this
What is a nebula?
100
This type of chart shows the relationship between a star's absolute magnitude, surface temperature, and age.
What is an H-R diagram?
200
This is the measure of the actual brightness of a star.
What is absolute magnitude?
200
This is the scientific name for the "North Star".
What is Polaris?
200
Very massive stars will give off their outer layers in a gigantic explosion called this
What is a supernova?
200
This is the force that pulls together bits of gas and dust in order to from a star
What is gravity?
200
This object in space is made when the center of a massive star collapses under its own gravity. Its gravity is so great that not even light can escape it.
What is a black hole?
300
A star is a giant ball that is made out of this state of matter (according to your book).
What is gas?
300
This pattern of stars is said to resemble a great hunter. His "belt" contains the star Betelgeuse.
What is Orion?
300
When the sun is very, very old, it will become this type of star. It is the leftover remains of a star's center, which are very hot and dim.
What is a white dwarf?
300
When a star is formed, it then becomes this type of star- an "average" or "normal" star.
What is a main-sequence star?
300
This type of star is a spinning kind of neutron star.
What is a pulsar?
400
This is the apparent shift in a star's position as it is viewed fro Earth.
What is parallax?
400
Besides the sun, this is the brightest star that is seen from Earth.
What is Sirius?
400
After a very massive star explodes within a supernova, its center core may become this type of star, which is made of uncharged particles and gives off light and radio waves.
What is a neutron star?
400
A new star is considered to be born when it is hot enough to perform this process, which helps the star create energy.
What is nuclear fusion?
400
A light-year is a measure of this
What is distance?
500
By looking at this band of color, scientists can determine the temperature and composition of a star.
What is a spectrum?
500
This is the closest star to the Earth.
What is the sun?
500
After a very old "average" star has given off all of its leftover energy, it is believed to become this very small, dark, cool type of star.
What is a black dwarf?
500
Very massive young stars are this color.
What is blue?
500
When atoms of this element collide during nuclear fusion, they become helium atoms and give off light and heat energy.
