Modern Astronomy
This theory states that matter is constantly being created to maintain the density of the expanding universe.
What is the Steady State Theory?
This was the first step of the Big Bang
What is the singularity?
Stars counteract the force of gravity and maintain a constant volume through this process.
What is nuclear fusion?
Earth's atmosphere prevents most of this type of radiation from reaching the surface. Don't leave your sunscreen at home though.
What is UV radiation?
Stonehenge
What is an example of a solar calendar?
This Flagstaff astronomer is credited with the discovery of red-shifted stars
Who is VM Slipher?
Recombination was followed by this stage
What is the dark ages?
Stars are generated from dense clouds of this element
What is hydrogen?
The most energetic type of electromagnetic radiation.
What are gamma rays?
This piece of technology is credited as being invented in the Netherlands at the beginning of the 17th century
What is the telescope?
This astronomer is credited with the creation of the stellar classification system.
Who is Annie Jump Cannon?
This phenomena is credited with being a proof of the Big Bang Theory
What is Cosmic Microwave Background Radiation?
The sun makes this element to generate energy.
What is helium?
The speed of light.
What is the velocity of electromagnetic radiation?
The observation that this planet had phases similar to those seen on the moon helped Galileo to finally discredit the theoy of geocentrism.
What is Venus??
This technology allowed for the discovery of the CMB.
What are radio telescopes?
This is postulated as being responsible for the acceleration of the expansion of the universe
What is dark matter?
Proton-Proton chain, Alpha capture, CNO cycle
What are different types of stellar nucleosynthesis/examples of nuclear fusion?
These 4 types of electromagnetic radiation are streaming through the classroom at this very moment.
What are visible light, infrared light, microwaves, and radio waves?
This astronomer formulated the Laws of Planetary motion
Who was Johannes Kepler?
The predictable pulsations of this type of star allows for an accurate measurement of distance from the observer
What are Cepheid stars?
The five steps of the Big Bang
What are Singularity, Expansion, Nucleosynthesis, Recombination, and the Dark Age?
These are created in supernovae, and in collisions between neutron stars.
What are elements heavier than iron on the periodic table?
The wavelength and frequency of EM radiation have this type of relationship.
What is an inverse relationship?
This ancient astronomer correctly surmised the correct relationship between the earth and the sun (heliocentrism) based on careful observations.
Who was Aristarchus of Samos?
