100
The galaxy with a low star count.
What is the Milky Way?
200
The two significant discoveries Edwin Hubble made.
What is the confirmation of the existence of other galaxies besides our own, and the determination that these galaxies are moving away from us and that the farther they are, the faster they are moving.

The two most useful techniques of measuring distances in space.
What is Cepheid variable stars and red shift?
200
The product of nuclear fusion.
What is the formation of helium nuclei through fusing of hydrogen nuclei?
200
The first black hole discovered.
What is Cygnus X-1?
200
The most dominant gravitational force in our universe.
What is dark energy?
300
The length of time ago that scientists believed the big bang occured.
What occured 13.7 billion years ago?
300
The definition of both absolute and apparent magnitude.
What is the actual amount of light the star gives off, recorded at a standard distance, and the brightness of a star as it appears in the night sky.
300
How stars form.
What occurs when nebulae collapse on themselves?
300
The mass of a white dwarf.
What is no more than 1.4 solar masses?
300
This is where dark matter is located.
What is in the outer fringes of a galaxy?
400
The method astronomers use to gather information on the big bang theory.
What does looking back in time provide to astronomers?
400
The definition of Cepheid variable stars and red shift.
What is one of the standard candles of the universe that are of known brightness, and the shift of the spectral lines toward the red end of the visible spectrum when light from a stars or galaxies is examined through a spectroscope?
400
The layer of the sun made of churning gasses, and an interesting feature of the layer.
What is the photosphere and has the visible part of the sun, and/or it does not have a solid surface?
400
The product of carbon fusion.
What is iron and nickel?
400
A type of galaxy that has a section of stars in the middle.
What is a barred spiral galaxy?
500
The evidence of the Big Bang did both the COBE and WMAP discovered
What is found very slight differences in the temperature of the cosmic microwave background radiation? What conformed the age of the universe to be 13.7 billion years plus or minus 200 million years?
500
The definition of baseline, and the longest possible baseline for astronomers use.
What is an imaginary line from which the distance to an object is measured and the length of the baseline is known, and Earth's orbit?
500
When materials of the get cooled, and sink back inside. Granules (convection cells) are formed when this occurs.
What happens to the heated materials that rise to the surface of the sun, and what forms because of this?
500
How a new world could possibly be formed.
What could be the result of a shock wave that will blow off the stars remaining material into space?
500
Blue giants are in this section of the galaxy. They are more visible than the sun because of this feature.
What are in the arms of a galaxy? What is the product of them being several thousand times brighter than the sun?
