Foundations
It's the direction the sun rises in the summer in Chicago.
What is north of east?
It places the Sun at the center of the universe, with the Earth and other planets orbiting around it.
What is the heliocentric model of the universe?
It's the pattern of lines that are seen when light given off from glowing hot gas is put through a prism.
What is an emission spectrum?
This reveals a star's temperature, chemical composition, and its motion along our line of sight.
What is a star's spectrum?
This astronomer had a pewter nose and a pet moose.
Who is Tycho Brahe?
It occurs when the Earth is positioned between the Sun and the Moon, casting Earth's shadow on the Moon.
What is a lunar eclipse?
It is caused by the gravitational pull of the Moon and results in the slow change in Earth's rotational axis.
What is axial precession?
This is the reason a measured wavelength will be longer than the actual wavelength when wave source is moving away from an observer.
What is the Doppler Effect?
It's the analysis of the way atoms absorb and emit light.
What is spectroscopy?
It's the subject that Tycho Brahe had a sword fight over with a a fellow student.
What is mathematics?
There are 60 arc minutes in this.
What is a degree?
This astronomer found that orbits of planets are ellipses.
Who is Johannes Kepler?
This is the the number of wave cycles that pass a fixed point in a given unit of time.
What is the frequency?
It's what determines at what wavelength a blackbody's energy peaks.
What is temperature?
It was the name Galileo gave to the character meant to represent the Pope in his Italian-language book "A Dialogue Concerning the Two Chief World Systems.
Who is Simplicio?
This is a lunar phase that occurs after the new moon and before the first quarter.
What is a waxing crescent?
The telescope enabled this astronomer to make groundbreaking observations of celestial bodies.
Who is Galileo?
These are the two forms of electromagnetic radiation that penetrate the atmosphere best.
What are visible and radio waves?
According to Bohr's model, these subatomic particles only make transitions between orbitals of specific energies.
What are electrons?
He is the Greek Mathematician credited with the earliest accurate measurement of Earth's circumference.
Who is Eratosthenes?
This is the time it takes for the Earth to rotate 360° in relation to a fixed point in the sky.
What is a sidereal day?
This law expresses that the farther a planet is from the Sun, the longer its orbital period.
What is Kepler's 3rd law?
This is a theoretical object that absorbs all light that hits it.
What is a blackbody?
An emission spectrum can be used to identify this.
What is an atom?
He is the man credited with inventing the telescope
Who is Hans Lippershay?
