Stars
This is a cloud of gas and dust that is the "nursery" or birthplace for stars
What is nebula?
How old the the Big Bang predict the universe to be?
10-15 billion years
Which is larger, a galaxy or the universe?
Universe
The unit of measure often used in outer space
a lightyear
Which type of galaxy contains older stars with little gas or dust
Elliptical
Most stars are in this category
Main Sequence
This model of the universe places the Earth at the center
Geocentric
One force that keeps the moon orbiting Earth.
What is gravity?
an infant star
protostar
This type of galaxy has a mixture of old and young stars
spiral galaxy
As surface temperature increases on a star, this also tends to increase
Luminosity
Irreducible complexity and intelligent design are used to support the idea of?
Creation
What is the name and type of galaxy we live in?
Milky Way, spiral galaxy
a pattern of stars in the sky, often used for navigation and storytelling,
Constellation
This type of galaxy has a large amount of gas and dust, no distinct shape and mostly young, blue stars
irregular
This is the brightness of a star as seen from Earth
Apparent magnitude
Redshift shows expansion, the composition of stars, and cosmic background radiation
This type of statement is universal and absolute, and sometimes can be described mathematically
A law
The apparent shift in position of a star when viewed from two locations. It is used to determine the distance to nearby stars.
parallax
Why are blue stars considered younger than red stars?
Blue stars burn their fuel more quickly, leading to a shorter "lifecycle"
Which stars will not go supernova at the end of their lifecycle? What will happen to them instead?
Low mass stars will become white dwarfs instead.
This model of the universe was popularized by Galileo
Heliocentric
A star and the objects that orbit it is called this
What is a solar system/planetary system
The device used to take the information out of visible light to determine the composition of stars
Spectrograph
Give two of the reasons the Big Bang is considered a theory instead of a law
1. complex and changing 2. Generally accepted to be true 3. used to make predictions 4. established by multiple scientists and tests
