Classifying Galaxies
Star Properties
Gravity vs. Fusion
Colors, Magnitude and Mass of stars
Extra Points, each worth 10 points
100
Has a nucleus with old stars, dust, gas and a black hole, and has curving arms rich with dust, gas, and young stars.
What is Spiral Galaxy
100
Temperature, size, color and magnitude.
What is Properties of stars
100
The process in which light nuclei combine at extremely high temperatures forming heavier nuclei and releasing energy
What is Fusion
100
Temperature
What is color based on?
100
Main sequence
What is the current stage of the Sun?
200
Like a spiral galaxy except with a bar through the center. It also the type of galaxy the Milky Way is.
What is barred spiral
200
Nebula,main sequence, red giant, and white dwarf
What is the four main stages of a star
200
Gravity>outward pressure/fusion
What is the cause of collapse?
200
Long waves, low frequency
What is cooler temperature caused by?
200
Milky way
What is the name of our galaxy?
300
Spherical dense collection, with low gas, dust and older stars and has a black hole in center.
What is Elliptical Galaxy
300
Highest temperature, and fusing H to He
What is Main Sequence
300
Outward pressure/fusion>gravity
What is the cause of expansion?
300
Short waves, High frequency
What is the cause of hotter temperatures
300
In the center of universes
What is the location of black holes?
400
A random collection abundant with gas and dust. It contains young stars and no noticeable shape
What is Irregular galaxy
400
Not very hot, and final stage
What is White Dwarf?
400
Equilibrium/ same size
What is gravity=outward pressure=
400
Big=Bright Small=Dim
How is magnitude based on size?
400
He was the first to classify galaxies
What is the major thing Edwin Hubble did?
500
A cloud of gas and dust left over from an exploding star, and from which some stars can form
What is nebula
500
Fusing H, and first stage
What is Nebula
500
The balance or lack of balance between outward pressure from fusion and collapse due to gravity
What is the way to determine what stage a star is in and when it will change
500
Small-medium stars have a longer life span than large stars, and they become white Dwarfs, while the large stars become supernovas.
What is the difference between the life spans of stars
500
Young stars are located on the arms of this galaxy
