Origin and
Age of the
Universe
Celestial Object
Any object outside or above Earth’s
atmosphere

Universe
Everything that exists in any place –
all the space, matter, and energy in
existence

Big Bang Theory
States that all matter and energy
started out concentrated in a small area
and, after a gigantic explosion, matter
began to organize into subatomic
particles and atoms.

Doppler Effect
The shifting of wavelengths
http://dragonphysics.pbworks.com/f/1234547786/gene%20waves_doppler.gif
Blue Shift
This results when the Earth and
another celestial object are coming
closer together and the electromagnetic
waves are bunched together

Red Shift
This results when the Earth and
another celestial object are moving
apart and the electromagnetic waves
are spread out

Structure
of the
Universe
Galaxy
A collection of billions of stars and
various amounts of gas and dust held
together by gravity

Milky Way Galaxy
Our solar system is a part of this spiralshaped galaxy
http://www.sciencenewsforkids.org/articles/20050202/a667_6174.jpg
Star
Usually a large ball of gas held together
by gravity that produces tremendous
amounts of energy and shines

Nuclear Fusion
Combining of the nuclei of smaller
elements to form the nuclei of larger
elements with some of the mass being
converted into energy
http://www.lancs.ac.uk/ug/hussainw/fusion.jpg
Luminosity
Measures how bright a star would be in
relation to the sun if all stars were the
same distance from an observer
http://www.daviddarling.info/images/luminosity_class.jpg
Solar
System
Solar System
The sun and all objects that orbit the
sun under its gravitational influence
http://horoscopicastrologyblog.com/wp-content/uploads/2008/11/solar-system.jpg
Asteroid
A solid rocky and/or metallic body that
independently orbits the sun
http://www.spacedaily.com/images/asteroid-617-patroclus-binary-jupiter-orbit-desk-1024.jpg
Moon
Body that orbits a planet or asteroid as
those objects orbit the sun
http://scienceblogs.com/startswithabang/upload/2009/08/paper_folding_to_the_moon/moon_2_bg_0722021.jpg
Comet
•Mainly composed of solids that easily
change to gases when heated
•Largely ices of substances such as water
and methane mixed with rocky or metallic
solids
http://www.astro.cornell.edu/academics/courses/astro2201/images/comet_west.gif
Meteor
Very small solid fragments that orbit the
sun

Impact crater
A depression in the Earth’s crust
created by a meteorite that has
sufficient mass
http://www.lpi.usra.edu/science/kiefer/Education/SSRG2-Craters/meteor_crater.gif
Impact Event
Even after Earth and
other planets formed,
their gravitational forces
pulled on the smaller
clumps of matter to
cause comets, asteroids
and meteoroids to collide
with planets in what is
called….
Planet
Characteristics
Terrestrial Planets
•Close to the sun and mostly solid
•Relatively small diameters and high densities
•Rocky surfaces are dotted with impact craters
•Have few or no moons and have no rings
•Planets similar to Earth including: Mercury, Venus, Earth
and Mars

Jovian Planets
•Far from the sun
•Relatively large diameters and low density
•No solid surfaces and no craters
•Have many moons and rings
•Are planets similar to Jupiter including: Jupiter, Saturn,
Uranus and Neptune

Rotation
Planets spin with this motion on an
imaginary axis, amount of time it takes
for a planet to spin one time around its
imaginary axis determines the length of
its day
http://www.physicalgeography.net/fundamentals/images/earth_rotation.jpg
Revolution
A planet’s movement around the sun in
a path called an orbit

Ellipse
Oval shaped orbit made by the Earth
http://www.astronomyforbeginners.com/images/diagrams/ellipse_orbit.gif
Foci, Focus
Fixed points within the ellipse

Eccentricity
The degree of flattening or “ovalness”
of an ellipse is measured by this

Inertia
The concept that an object at rest will
tend to remain at rest, and that an
object in motion will maintain the
direction and speed of that motion
unless an opposing force affects it
http://www.asc-csa.gc.ca/images/spacesuit_inertia.jpg
Gravitation
Attractive forces that exist between any
two objects in the universe
