What makes Sirius the brightest star in the sky?
What is its apparent magnitude
200
What is a galaxy without a definite shape?
What is irregular galaxy
200
What is a white dwarf?
What is stage in stars life when the core of a main sequence star uses up its helium
200
What is the Big Bang Theory
What is a theory that 15-20 billion years ago the universe began expanding out of an enormous explosion
200
Prominences, sunspots,and flares are caused by what
What is an intense magnetic field on the sun
300
What is the difference between apparent and absolute magnitude
What is apparent magnitude - the measurement of light recieved on Earth from a star, absolute magnitude - the measure of the amount of light given off by the star
300
What kind of galaxy is the Milky Way
What is barred spiral galaxy
300
Draw the life cycle of a star from beginning to white dwarf
What is nebula to low-mass star to main sequence star to red giant to white dwarf
300
What is parallax?
What is apparent movement of a star used to measure its distance from the Earth
300
Our sun is in what range on the H-R diagram
What is main sequence
400
A red-shift in the spectrum of light indicates what?
What is that the object is moving away from you
400
How far across is the Milky Way Galaxy?
What is about 100,000 light years
400
Draw and label the life cycle of a star from beginning to end with neutron star or black hole as the end.
What is nebula to high-mass star to red supergiant to supernova to either neutron star or black hole
400
What is a light-year
What is distance based on speed of light
400
Why is our sun unusual?
What is it does not belong to a binary star system
500
Why does the position of Orion appear to change throughout the year and why cant we see it in the summer?
What is Because Earth revolves around the Sun, the position seems to move. Because the Earth rotates on its axis we see it in the daytime in the summer.
500
How does the Big Bang theory explain the Doppler effects?
What is The Big bang theory staes that the universe was created and is expanding due to a large explosion, the Doppler shift to red indicates that galaxies outside the Local Group of moving away indiacted that the universe is expanding also.
