Regions most stars spend time in
The Main sequence
what galaxy has middle bulged with arms
spiral
where do stars come from
Nebula
Inner layers of the sun
The core,radiative zone,Convection zone
apparent magnitude definition
how bright the stars look from earth
Two things graphed on a H-R graph
Temperature and brightness
what galaxy has no shape
Elliptical
what color are the hottest stars
Blue
Outer layers of the sun
Photosphere, the Chromosphere, the Transition Region and the Corona
Luminosity
how much light a star is giving off

the core
absolute definition
how bright or big a star is compared to other stars
what are other stars that are not in the main sequence
blue giants,red giants,white dwarfs
What is a galxy
Large group of stars held by gravity
what are stars made out of

H-R diagram meaning
Hertzsprung-Russel diagram
what stars in the main sequence are at the top left
Closest Galaxy to the milky way
Andromeda
low mass star cycle
Nebula-main sequence-red giant-planetary-white dwarf-black dwarf
why do most stars appear white
Because stars are a lot of colors but our eyes form it into one color which appear to be white
white dwarf
low mass,cool,white stars,the result of small stars running out of fuel
