The leading theory about the formation of the universe.
What is the Big Bang Theory
200
The measure of the amount of light a star gives off IF, we could line up all the stars the same distance from Earth
What is apparent magnitude
200
These are a result of a CME, a coronal mass ejection
What is a solar storm

True or False. Small stars live longer than large stars since smaller once burn fuel at a slower rate.
What is TRUE
200
The name of the galaxy where Earth is located that is part of a cluster of galaxies known as the Local Group
What is the Milky Way
200
The name of the term that supports the Big Bang Theory and is the evidence that shows that galaxies beyond the Local Group are moving away from Earth.
What is red shift
300
A unit of measurement used to measure the distances between stars and galaxies
What is a light-year
300
The Sun is an example of this type of star
What is a main sequence star
300
Extremely massive stars are born, the become main sequence stars, the grow into red supergiants, supernova and then form this
What is a black hole
300
Galaxies, stars and the Universe. The one that is the smallest of the three.
What is a star
300
An astronomer investigating a star determines that the light wavelengths she observes are longer than those expected to be emitted by the star. This information says that this star must be moving in this direction in comparison to the Earth's position.
What is moving away from the Earth

What is a spiral galaxy
400
The color of light from a star that is moving toward an observer on Earth
What is blue.
500
The birthplace of a star; a cloud of gas and dust in space
What is a nebula
500
The element that the Sun fuses to produce the energy and light it gives off
What is hydrogen
500
The two forces that oppose each other and are constantly battling inside of a star
What are gas pressure and gravity
500
The term given to a group of galaxies.
What is a cluster
500
The term used to describe the movement in spectral lines toward either the red or blue end of the visible spectrum to support the Big Bang Theory
