Big Picture Basics
This model placed Earth at the center of the universe.
Geocentric model
This type of telescope uses lenses to magnify objects.
Refraction Telescope
This force pulls masses together throughout the universe.
Gravity
The distance light travels in one year is called this.
A light year
A measurement from a set point measuring "up".
Altitude
This scientist proposed the heliocentric model in the 1500s
Nicolaus Copernicus
This type of telescope uses mirrors to collect light.
Reflection Telescope
This process powers stars by combining small atoms into larger ones.
Nuclear Fusion
The distance between Earth and the sun is called this unit.
Astronomical Unit
The Olympus Mons is the largest volcano in our Solar System. Which planet does it belong to?
Mars
These are giant clouds of gas and dust where stars form
Nebulas
This is the angle measured from true north moving clockwise.
The study of light from stars is called this.

Canadarm 2
What is the name for a large grouping of stars and solar systems held together by gravity?
A galaxy
Scientists use this method to estimate distances of far off objects using angles
Parallax (Or triangulation)
If a star is moving away from Earth, its light shifts toward this colour.
Red
Gas giants like Jupiter and Saturn belong to this category.
Gaseous
What is a potential consequence to astronauts in space who are exposed to solar radiation?
Radiation sickness, increased cancer risk, degenerative diseases, CNS damage
Put these in order from smallest --> largest

30x
These missing lines in a star’s light spectrum help scientists identify elements.
Atomic Fingerprints (Absorption Lines)
This is the name of our galaxy.
The Milky Way
