The property of stars that scientists use to determine the temperature of a star.
What is color?
100
Nebula, then protostar, main sequence, red giant, planetary nebula, white dwarf
What is the life cycle of a low mass or medium mass star?
100
Huge, arching columns of gas between the magnetic field of sunspots on the Sun.
What is a prominence?
100
A type of galaxy that resembles a pinwheel.
What is spiral galaxy?
100
Contains over a 100 billion galaxies.
What is the universe?
200
Found in the constellation of Orion, this red supergiant will someday (perhaps already has) explode as a supernova.
What is Betelgeuse?
200
This stage occurs when the core of a medium mass star has fused all of its hydrogen into helium.
What is a giant?
200
The outer most layer of the sun's atmosphere. Can only be seen during a total solar eclipse
What is the corona?
200
A type of galaxy so little room for gas and dust it contains only older stars.
What is elliptical galaxy?
200
The evidence used to infer that most galaxies are moving away from the Milky way
What is the red shift?
300
The most common elements in which stars are composed of.
What are hydrogen and helium?
300
The one factor that determines the outcome of a star's life cycle.
What is starting mass?
300
Dark regions on the Sun's surface that are cool.
What are sunspots?
300
2,650,000 light-years away, it was the first galaxy discovered. It is a spiral galaxy and the largest member of the Local Group.
What is Andromeda?
300
The astronomer who discovered the galaxies are moving away from each other.
Who is Edwin Hubble?
400
This is determined by the size and temperature of a star.
What is luminosity?
400
A pulsar is evidence for this kind of star.
What is a neutron star?
400
The layer of the Sun's atmosphere that produces light.
What is the photosphere?
400
how far away our sun is from the center of the galaxy
What is halfway down a spiral arm, about 25,000 - 26,000 light years away?
400
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?
500
Also known as apparent magnitude, this describes how a star is see from Earth.
What is brightness?
500
As a star's luminosity increases, its surface temperature increases.
What is relationship shown on the H-R diagram for main sequence stars?
500
the particles that can affect Earth's upper atmosphere causing magnetic storms.
What is solar wind?
500
The shift that shows the expansion, or lengthening, of wavelengths by the spectroscope.
What is red shift?
500
What are two pieces of evidence that supports the big bang theory.
What are the red shift of all galaxies and cosmic background radiation? oh yeah....the low % of universal heavy elements
