The explosion that lead to the universe.
What is the Big Bang?
This shows where radiation falls in relation to eachother.
What is the Electromagnetic Spectrum?
What is luminosity?
The beginning of star formation starts with this.
What is an interstellar cloud of dust?
This law states that planets orbit in ellipses not circles.
What is Kepler's 1st law or the law of orbits.
Radiation we use as evidence of the Big Bang.
What are Microwaves?
Patterns of distance between waves from electromagnetic radiation.
What are wavelengths?
What you observe when looking at a star.
What is apparent brightness?
The shape that forms from all the particles/dust as stars are forming.
What is a disc?
Py^2=rAU^3 is an equation that states this.
What is the period in years squared is equal to the distance in Astronomical units cubed?
When visible light wavelength is stretched out as light producing object moves further away.
What is red shifting?
How many sections the EM spectrum is divided into.
What is 7 sections?
Does not change if a star moves closer or further away.
What is Luminosity?
This left over interstellar dust and particles form these after stars are formed.
What are planets?
This law states that there is a correlation between the period of a planet and the distance it is from its star.
What is Kepler's 3rd law or law of periods?
Change in wave frequency as wave producing object moves further or closer.
What is the doppler effect?
Decrease in wavelength lead to this.
What is an increase in energy?
Is affected by how close the star is.
What is apparent brightness?
The element that fuses together in stars to form helium.
What is hydrogen?
This law states that a planets traveled distance within an interval of time will always produce the same area.
What is Kepler's 2nd Law or the Law of Areas?
States that objects further away move away faster, and objects closer move away slower.
What is Hubble's Law?
Increase is wavelength lead to this.
What is a decrease in energy?
This is how you would define apparent brightness.
This causes the cloud of dust and particles to begin forming clumps.
As eccentricity approaches 1 the ellipse becomes more this.
What is flat?
