The Universe

Big Bang Theory At one time, the entire universe was confined to

a dense, hot, super massive ball. Then, about

thirteen point seven billion years ago, a violent explosion

occurred hurling all this material in every

direction.

Expansion of the Universe The red shift of galaxies

indicates the universe is still expanding.

Scientists discovered a form of energy known as cosmic background radiation. This energy was found radiating from an unknown source in space.

Structure of the Universe Planets, stars, and gases

only make up 5% of the universe. The other 95% is

dark matter and dark energy. The organization

follows a hierarchical model that only extends

to super-clusters and filaments. Beyond that

there is no clear organization.

Probing the Universe

The Technology used in probing the universe include

a high energy telescope known as The High Energy

Focusing Telescope. This telescope uses high

energy x-ray focusing modules used to examine highly energetic objects in

space.

Facts about Mercury

Mercury looks like the Moon.

It is dark and cold when far away from the Sun, and light and hot

when it is near the Sun.

Mercury is straight up

and down on its axis.

Life on Mercury?• There is no atmosphere at all. There are no clouds, which

means there is no water to rain down.

• There is no water, so there is no food either.

• Because there is no atmosphere, there are no plants, and there are no animals.

• If there are no animals, there can be no people because people eat animals.

• Even though there is no atmosphere, there is still gravity.

Venus

The Earth and Venus are like sisters because they are the same size and both have electricity and heat. Venus also has volcanoes and mountains.

Life on Venus?

• It is too hot (864 degrees F) and there’s no water. Venus does not have people or houses because Venus is so hot.

• The Sun blasts it and there is a really hot “blanket” called its atmosphere.

• It has electricity on it.

Earth• The Earth is a round planet with other

planets all around it.

• The Earth has many continents.

• It has one moon.

EarthThe Earth has a magnetic field that protects it from the Sun’s radiation.

If the Earth didn’t have the magnetic field, the Sun would burn us.

The Inside of the Earth

Magma

Crust

Mars• Mars has possible life because it has water.

• Not as much gravity

• Some energy from the Sun

• Not as much air

• Really cold - unsuitable for people

• Colder at the poles

• Two rovers on Mars - Spirit and Opportunity

Jupiter• Jupiter has all dots and lines all over it. This

is weather. Jupiter has a black and white dot - does that mean that the black dot gets very bad winds?

• If you tried to step on Jupiter, you would go to its core because Jupiter is all gas and there is no land.

• If you throw a match at Jupiter, it would crumple up and explode.

Jupiter• If you put Jupiter in the Sun, it would burn

up.

• Jupiter is really cold. (-234 F)

• There is no oxygen, so there is no life. There is no air that we can breathe.

• Jupiter has 63 moons..

• Jupiter’s gravity is so awesome!

• Io has volcanoes. When it is next to Jupiter, it erupts a lot.

Saturn• Saturn’s rings are made of rock. Some of

the rocks are big. Some have been turned to dust.

• Saturn’s hurricanes are way bigger than Earth’s. They are bigger than Earth itself!

• Saturn is the 2nd biggest planet in our solar system.

• Saturn has a moon called Titan which might be the only moon we know that has life.

Saturn

• Saturn has lots of moons.

• Saturn is like the Sun, except it is not a star because it is too cold. Saturn is almost made out of what the Sun is made out of. It would take thousands of Saturns to create one Sun.

• Saturn has no life on it because you can’t even step onto it. It’s made out of gas. You would be crushed.

• Saturn is cold. (-288 degrees F)

• One of Saturn’s moons, Mimas, looks like the Death Star.

Uranus• Uranus is blue and is tilted.

• You can’t really see the rings because they are made out of dust.

• Uranus is made out of gas and ice.

• This planet has 27 different moons and counting.

• Uranus’s moons are all named after characters from Shakespeare’s plays.

• Neptune has rings made of dust particles.

• Neptune has a big hole that scientists think is a hole in the atmosphere, or bad, bad weather.

• The white areas on Neptune mean that there is weather there.

• Neptune is blue because of its atmosphere.

• Neptune is the farthest planet from the Sun that has rings. It is also the farthest planet, period.

• It is very cold on Neptune.

Neptune

Pluto• Pluto is quite small.

• Pluto is a dwarf planet. Pluto is not a real planet.

• Pluto is too cold for its atmosphere to keep from freezing. Pluto has an atmosphere when it is close to the Sun.

• Pluto has 3 moons. One of them is part of a “double planet” with Pluto.
