H-R Diagram
These are the 2 axes on the H-R Diagram (x and y)
What are temperature and luminosity?
This is how all stars begin
What is a stellar nebula?
This is the type of star that can make a black hole
What is a very massive star?
This scientist discovered that galaxies are moving away from us, supporting an expanding universe
Who is Edwin Hubble?
This type of wave has the longest wavelength and lowest energy
What are radio waves?
This is the type of star on the H-R Diagram our sun is
What is a Main Sequence Star?
This is the end result of a medium mass star
What is a White Dwarf?
This is the invisible "edge" of a black hole, where nothing can escape
What is the event horizon?
This is radiation left over from the Big Bang that was detected by Penzias and Wilson in the 1960's
What is Cosmic Microwave Background Radiation?
What is a dime?
This is the color of our hottest stars
What are blue or white
These are the two possible end results of a very massive star
What are Neutron Star or Black Hole?
This is the type of wave that scientists discovered coming from a black hole
What are gravitational wave?
These are the 2 elements that fill most of the universe
What are hydrogen and helium?
These waves are shorter than visible light waves and can cause sunburns
What are ultraviolet (UV) waves?
The type of star our sun will become after a Main Sequence Star
What is a Red Giant?
This is where a planetary nebula fits in the Life Cycle of a Star
What is between Red Giant and White Dwarf?
This happens when a black hole stretches an object because of strong gravitational differences
What is spaghettification?
This is what happens to stars that are moving away from us
What is red-shifting?
This is the relationship between frequency and energy
What is the higher the frequency, the higher the energy?
These are the types of medium mass stars on the H-R Diagram
What are Main Sequence, Red Giant, White Dwarf, and Blue Giant
This is the stage of a very massive star after Red Giant
What is a Supernova?
These are what shoot from the "accretion disk" of a black hole
What are jets?
This is the name of a reverse of the Big Bang, when space condenses instead of expands
What is the Big Crunch?
This is the relationship between wavelength and energy
What is the longer the wavelength, the lower the energy?
