Front 8

Saturn
(titan, cassini division, ringlets)

Back 8

Titan- thick nitrogen atmosphere
Cassini Division- gap in Saturn's rings due to tides from shepherding moons
Ringlets- Saturn's rings are small ringlets, again may be due to shepherding moons

Back 17

small piece in space

Front 18

Meteor

Back 18

burning up in out atmosphere

Front 19

Meteorite

Back 19

rock on the ground

Front 20

Photosphere

Back 20

part of the sun we see
about 500 miles thick
5800K

Front 21

Chromo sphere

Back 21

pink
10000 miles above photosphere
15000K

Front 22

Corona and Holes

Back 22

outer atmosphere
1,000,000K+
areas which have no coronas are called holes

Front 23

Luminosity

Back 23

how much energy the sun gives off
use sun as standard unit of 1 solar lum.

Front 24

Convection Zone

Back 24

area just below the surface that energy moves and undulates sun surface

Front 25

Radiation Zone

Back 25

area around core of sun that moves the energy

Front 26

Core

Back 26

15,000,000K dense
all fusion takes place here

Front 27

Helio Seismology

Back 27

study of convection undulations below surface

Front 28

Granulation

Back 28

salt and pepper texture on surface due to convection

Front 29

Sunspots

Back 29

magnetic storms cooler by 2,000K on suns surface

Front 30

Cycle

Back 30

11 years, if you look at numbers
22 years, if you look at polarity switch

Front 31

Prominences

Back 31

loops of gases that connect paired sunspots

Front 32

Flares

Back 32

hot storms that last 5 to 20 minutes
5 million degrees sends out a lot of x-ray and solar radiation

Front 33

Fusion

Back 33

combining hydrogen into helium which releases energy only in core

Front 34

PxP reaction

Back 34

reaction that takes place in suns core
4 hydrogen to 1 helium

Front 35

E=mc2

Back 35

E=energy
M=mass
C= speed of light

Front 36

Neutrinos

Back 36

essentially mass less particles that are created at suns core and may let us study the core.
