What is a spectroscope?
The Sun rotates in this amount of time.
What is 1 month (25ish days)?
This color star is the hottest.
A majority of the sun's features are caused by this.
What are magnetic fields?
Shorter wavelengths of light mean frequency is _______ and energy is _______.
This type of telescope is so large because it has to collect very large wavelengths.
What is a radio telescope?
Nuclear fusion in the Sun involves taking ______ and making it into _______ and _______.
What is Hydrogen, Helium and energy?
Absolute magnitude is how bright a star ______ is, apparent magnitude is how bright a star ____________.
What is actually, appears on Earth?
A majority of star's have this type of spectra.
What is absorption spectra?
The property of light that means it acts as both a wave and a particle.
What is wave-particle duality?
This type of telescope refracts light from the objective lens to the focus, which is then magnified by the eyepiece.
What is a refracting telescope?
This layer of the sun is the visible layer where you can see granules and sunspots.
This is the correct order of a sun sized star's life cycle (excluding birth). (5 stages)
What is protostar, main sequence, red giant, planetary nebula, white dwarf?
Hubble's Law states that galaxies are moving _____ from us at a speed proportional to their _______ from us.
What is away, distance?
These types of light have a lower frequency than visible light.
What is Infrared, Microwave, and Radio?
These elements exist in Mystery Star #3.
What is Hydrogen and Calcium?
This sun feature is from loops of plasma caught in magnetic loops.
What is a prominence?
These two things are in balance when a star is in main sequence (stop it from getting bigger)
What is gas pressure and gravity?
Hertzsprung-Russell diagrams show us the relationship between a star's ______ and ______.
What is absolute magnitude, temperature?
A star is blue, but it is moving away from us therefore is experiencing "red-shift", if it shifts just one color towards the red end of the spectrum it will look this color.
What is green?
These elements are present in the star spectrum
What is Hydrogen and Helium?
This feature of the sun can cause satellite problems, communication issues, and auroras on Earth.
What are solar winds?
This is the slight shifting in apparent position of a nearby object with the background due to a change in viewing position, it is also used to measure the distance of close stars.
What is parallax?
Elements larger than iron cannot be made during fusion in a star, what has to happen for those elements to be created?
What is a supernova?
