Team 1The Outer Planets and Comets,

• By Greg, Alex, Brittany, Freddy and Cameran

2
The four outer planets-Jupiter, Saturn, Uranus,
and Neptune-are much larger and more massive than
Earth, and they dont have solid surfaces.

• Outer planets called gas giants
• Each giant is surrounded by a set of rings-a thin
  disk of small particles and ice and rock

3
Jupiter

• Jupiter is the largest and most massive planet
• Has a thick atmosphere made up of mainly hydrogen
  and helium
• Has a great red spot that is made up of a storm
  that is larger than Earth and it is similar to a
  hurricane
• It has a dense core of rock and iron at its
  center
• It has over 63 moons and four large ones called
  Callisto, Io, Europa, Ganymede

4
Saturn

• Saturn is the second largest planet in our
  universe
• It has a thick atmosphere made up of mainly
  hydrogen and helium
• Its atmosphere also contains clouds and storms
• Saturn has many rings that are made up of chunks
  of ice and rocks
• Its largest moon is called Titan and it is
  larger than the planet Mercury

5
Uranus

• Uranus is a gas giant and is four times larger
  than Earth
• It is much smaller than Jupiter and Saturn
• Uranus has a blue/greenish color because of
  trace of methane in its atmosphere
• Its surrounded by a group of thin, round rings
  like Saturn only much less
• Its axis of rotation is tilted at an angle of 90
  degrees

6
Neptune

• Neptune is a cold, blue planet and its
  atmosphere contains visible clouds
• Scientists think that Neptune is slowly
  shrinking causing its core to heat up
• It has at least 13 moons going around it
• Its largest moon is called Triton which has its
  own thin atmosphere

7
Pluto

• Pluto has a solid surface and is much smaller
  and denser than the other outer planets
• It is smaller than Earths moon and is probably
  made of rocks and ice
• It is so far from the Sun it revolves around it
  about every 258 Earth years
• Until recently Pluto was considered the 9th
  planet in our solar system
• Now it is considered a dwarf planet

8
Comets

• Comets are loose collections of ice, dust and
  small rocky particles
• Its orbits are usually very long, narrow
  ellipses
• Most comets originate from one of two distant
  regions of the solar system
• They come from the Kuiper Belt of the Oort cloud
• As a comet approaches the sun, it heats up and
  some of the gas and dust streams outward forming
  a tail

Inner planetsEarth and Venus

• Earth Earth is unique in our solar system in
  having liquid
• water at its surface. Earth is 70 water.
• Atmosphere extends more than 100 kilometers
  above the surfaces. About 20 is oxygen and
  nearly all the rest is nitrogen with small
  amounts of other gases such as argon and carbon
  dioxide.
• Venus Venus takes about 7.5 Earth months to
  revolve around the sun and takes 8 months to
  rotate on its axis.
• Atmosphere Its atmosphere is so thick that
  it is always cloudy.

11
Mercury and Mars

• Mercury Smallest terrestrial planet and closest
  to the sun. Mercury has almost no atmosphere. Its
  high temperature causes gas particles to move
  very fast.
• Mars Marss atmosphere is more than 95 carbon
  dioxide. Scientists think that a large amount of
  liquid water flowed on Marss surface in the
  past. Because it is tilted on its axis it has
  seasons just like Earth.

12
Asteroids

• Asteroids are rocky objects that mostly revolve
  around the sun in fairly circular orbits between
  the orbits of Mars and Jupiter. This region of
  the solar system is called the asteroid belt.
• There are more than 100,000 asteroids discovered
  in the asteroid belt. Some asteroids are so big
  they are considered dwarf planets.

• Andy Eppright
• Alyssa Cheshire
• Bev Lincoln
• Tristan Collins

14
Satellites

• A Satellite is an object that revolves around
  another object in space.
• The moon is a natural satellite of Earth.
• A Spacecraft orbiting Earth is an artificial
  satellite.
• The first artificial satellite was named the
  Sputnik, its success caused great alarm to the
  United States.

15
Meteors

• When a Meteoroid enters Earths atmosphere,
  friction with the air creates heat and produces a
  streak of light in the sky , this is known as a
  Meteor.
• If the meteoroid is large enough, it may not
  disintegrate completely.
• If not completely disintegrated, it can pass
  through Earths atmosphere.

16
Meteorites

• A meteoroid that passes through the atmosphere
  and hits Earths surface.
• The crater in Arizona was created by a meteorite.

17
Meteoroids

• A Meteoroid is a chunk of rock or dust in space.
• Meteoroids come from comets or asteroids.
• Some form when asteroids collide in space.
• Others form when a comet breaks up and creates a
  cloud of dust that continues to move through the
  solar system.
• When Earth passes through one of there dust
  clouds, bits of dust enter Earths atmosphere.
• The creators on the moon were formed by
  meteoroids.

Team 4 Black Holes, Dark Energy and Dark Matter

• Devon Lum
• Gaimo Johnson
• Yareyci Rivera
• Katherine Gomez
• Joe Hamilton

19
Black Holes

• After a large star runs out of fuel, it implodes
  causing a super nova. The gravity mass is so
  strong that the gas is pulled inward, creating a
  black hole.
• No light, radio waves, or any other form of
  radiation can ever get out of a black hole, so it
  is not possible to detect a black hole directly.
• You can detect them indirectly.
• Black holes can be millions or even billions
  times bigger than the suns initial mass.

20
Dark Matter

• It is matter that does not give off
  electromagnetic radiation.
• Dark matter cannot be seen directly.
• But, its presence can be inferred by observing
  the effect of its gravity on visible objects,
  such as stars, or on light.
• Astronomers are still trying to find out what the
  Dark Matter is made out of.

21
Dark Energy

• Dark energy is a mysterious force that is causing
  the expansion of the universe to accelerate.
• Current estimates indicate that most of the
  universe is made of dark energy and dark matter.
• Less than 5 of the universe is made up of normal
  matter.

Team 5 Space Exploration(History and Future) and
Telescopes.

• By Michael Gray
• Trent Abbott
• Alexia Maganda
• Preet Oza
• Kristina Ybarra

27
History of Space

• A satellite is an object that revolves around
  another object in space.
• In late 1958, the United States established a
  government agency in charge of its space program
  called the National Aeronautics and Space
  Administration(NASA).
• On July 20,1969 Apollo 11 astronaut Neil
  Armstrong became the first person to walk on the
  moon.
• The astronauts collected nearly 400 kilograms of
  lunar samples, commonly called moon rocks.

28
The Future of Space

• In 2004, the U.S announced a plan to establish a
  permanent colony of people on the moon.
• Nasa used space shuttles to perform many
  important tasks. These included taking satellites
  into orbit, repairing damaged satellites , and
  carrying astronauts and equipment to and from the
  space station.

29
Telescopes

• All the colors you see in a telescope is called
  visible light. It one of many types of
  electromagnetic radiation.
• Telescopes are instruments that collect and focus
  light and other forms of electromagnetic
  radiation.
• The two major telescopes are refracting
  telescopes and reflecting telescopes.

30
The Sun

• Bailey Vaskov, David Zamora, Kelly Doherty, Emily
  Threlkel

31
The Suns Energy

• The sun accounts for 99.8 percent of the solar
  systems total mass.
• The sun is a huge ball of ionized gas, or plasma,
  thought.
• About three quarters of the suns mass is
  hydrogen.
• About one quarter of the suns mass is helium.

32
Nuclear Fusion

• The sun produces energy through nuclear fusion.
• In nuclear fusion two atomic nuclei combine,
  forming a larger. More massive nucleus and
  releasing energy.
• Within the sun, hydrogen atoms join together to
  form helium.

33
The Suns Interior

• The suns interior consists of the core, the
  radiation zone, and the convection zone.
• The core is where the suns energy is produced.
• The radiation Zone is region of very tightly
  packed gas where energy is transferred mainly in
  the form of electromagnetic radiation.
• The convection zone is the outer-most layer of
  the suns interior.

34
The Suns Atmosphere

• The inner layer of the suns atmosphere is called
  the photosphere.
• The sun does not have a solid surface.
• There are dark spots on the sun called sunspots.
• Sunspots are areas where the sun is cooler.
• The suns interior is about 1.4 million
  kilometers.
• Sun spots usually occur in huge, reddish loops of
  gas called prominences.

35
The Formation of the Solar System

• Bailey Vaskov, David Zamora, Dayton Wallace,
  Kelly Dohetty, Emily Threlkel

36
The Solar Nebula

• About five billion years ago, a giant cloud of
  gas and dust collapsed to form a solar nebula
• Gravity began to pull solar nebula together, as
  the solar nebula shrank and spun faster and
  faster. The solar nebula flattened, forming a
  rotating disk. Gravity pulled most of the gas
  into the center of the disk where the gas
  eventually became hot and dense enough where
  nuclear fusion to begin.

37
Planetesimals

• Planetesimals formed the building blocks of the
  planets, the planets grew larger.

38
The Planets

• When the Solar System formed the temperature was
  very high.
• Most gasses escaped the gravity of the planets,
  that were forming in this region, as a result the
  inner planets are relatively small and rocky.
• The planets farther from the sun are much colder.
  As these planets in this region grew, their
  gravity increased and they were able to capture
  much of the hydrogen and helium in space.

39
Evidence

• The composition of the inner and outer planets
  provides strong evidence for a solar nebula
  theory.
• Other evidence includes the position of the sun
  at the center of the solar system.
