Nebular Theory
Stars
small star
average star
fuses
hydrogen
helium
releases radiation or energy
Red Giant
uses its hydrogen
fuses helium
into heavier elements
oxygen
carbon
outer layer is cooler
cooler/larger star
red in color
white dwarf
star runs out of helium
uses its carbon
heavier elements
star will fail
gas expands
away from star
leaves behind
glowing carbon core
white dwarf
black dwarf
white dwarf runs out of energy
loses brightness
becomes a black dwarf
Massive star
bigger then a average star
10 times bigger
more massive then our sun
fuses hydrogen to helium
Red supergiant
massive star runs out of hydrogen
it expands
make all kinds of elements
until it forms
iron
Supernova
a star only has iron left
gravity will collapse it
until it explodes
after the supernova
core remains
if star is 4 times the size of the sun
becomes a neutron star
it's very small
black hole
if core is 5 times less then the sun
the core will collapse
into a black hole
a dense core
supermassive star
gravity is so strong
nothing can escape
not even light
Galaxies
Nebula
left from the big bang
leftover hydrogen
leftover helium
there are heavier elements
remains
collapsed stars
Gravity
pulls
gas
dust
Nebula shrinks
rotates
forms a disk
Planets form
Outer part of disk
dust clumps together
forms larger clumps
Large clumps attract clumps
clumps form
planets
moons
solar systems
Solar System
inner planets
Mercury
Smallest Planet
No moons
closest to the sun
Venus
No moons
greenhouse effect
atmosphere of CO 2
Earth
One moon
contains life
has liquid water
Mars
two moons
Phobos
Deimos
Largest volcano in the solar system
half the size of earth
Gas Giants
outer planets
Jupiter
largest planet
53 confirmed moons
16 unconfirmed
Saturn
53 confirmed moons
8 unconfirmed
Rings of dust, rocks, ice
Uranus
27 moons
methane gives blue appearance
rotates sideways
Neptune
13 confirmed moons
1 unconfirmed
dark spots are massive storms
