This way of measuring distance measures the time it takes for a laser beam to bounce off an object and come back.
What is radar ranging!
100
The Milky Way Galaxy was formed a) 1/3 of the age of the universe b) 1/100 the age of the universe c) almost the age of the universe d) less than 1/1,000,000 the age of the universe
What is c) almost the age of the universe? Universe age: ~13.77 billion years Milky Way Age: ~13.21 Billion years

This is anything that takes up space and has mass.
What is matter?

This neutron star has a short pulse, is highly magnetized, rotates, and emits a beam of electromagnetic radiation.
What is a pulsar?

If athletes get “Athlete’s Foot,” what do astronauts get?
What is "Missile Toe?
200
This way of measuring distance uses the distance between the apparent magnitude (m) of a star and it absolute magnitude (M). It is often seen as m-M.
What is distance modulus.
200
Recorded human history happened a) almost the age of the universe b) less than 1/1,000,000 the age of the universe c) less than 1/10,000 the age of the universe d) 1/3 the age of the universe
What is b) less than 1/1,000,000 the age of the universe Universe age: ~13.77 billion years Recorded human history: ~32,000 years (cave paintings) ~5,000 years (Sumarian Cuneiform Script)
200
This is made up of antiparticles (positively charged particles.
What is anti-matter?
200
These are the brightest electromagnetic events known to man. They are extremely energetic explosions of a specific type of radiation that can last from milliseconds to hours.
What are Gamma Ray Bursts?
200
What kind of songs do the planets like to sing?
What are Nep-TUNES?
300
This way of measuring distance takes two measurements from different angles and compares them. The difference, with a little trig, will give you the distance of an object.
What is parallax?
300
The Earth formed at a) almost the age of the universe b) 1/100 the age of the universe c) 1/3 of the age of the universe d) 2/3 of the age of the universe
What is d) 2/3 of the age of the universe? Universe Age: ~13.77 billion years Earth Age: ~4.54 billion years
300
This hypothetical stuff cannot be seen by a telescope, but accounts for most of the matter in the universe.
What is dark matter?
300
This a hypothetical, undiscovered form of energy which is thought to be in all of space, tending to accelerate the expansion of the universe.
What is dark energy?

How does the man in the moon cut his hair?
What is 'e-clipse it? ('e clips it! He clips it!)
400
This way of measuring distance measures the pulsation of a star. Based on the frequency of the pulsation, you can determine the distance.
What is cepheid variable stars?
400
The sun formed at a) almost the age of the universe b) 1/3 the age of the universe c) 2/3 the age of the universe d) less than 1/10,000 the age of the universe
What is c) 2/3 the age of the universe? Universe Age: ~13.77 billion years Sun Age: ~4.57 billion years
400
This space object has a gravitation pull so strong that no matter can escape it's gravitational field.
What is a black hole?
400
This is classified as an "active galaxy," believed to be powered by material built up into a super-massive black hole, and is extraordinarily bright.
What is a quasar?
400
How do you organize a space party?
What is you planet?
500
This method of measuring stars takes a cluster of stars and compares them to a cluster of stars of which the distance is known. Comparing them will give you the distance of the unknown star cluster.
What is main sequence fitting?
500
The cosmic microwave background forms at a) almost the age of the universe b) 1/100 the age of the universe c) less than 1/10,000 the age of the universe d) less than 1/1,000,000 the age of the universe
What is a) almost the age of the universe? Universe age: ~13.77 billion years Cosmic Microwave: Formed ~378,000 years after Big Bang0 (~13.77 billion years ago)
500
This star type lacks hydrogen in it's spectral reading and is used as a "standard candle" because they all burn with equal brightness and can be used to determine cosmic distances.
What is Type 1 Supernova?
500
In this effect, light passes through a gravitation field and is believed to bend because of gravity.
What is gravitational lensing?
