Moon LandingEnjoy this original footage of the NASA Apollo 11 moon landing on July 20, 1969. This moment started a new era for space exploration and is remembered through Neil Armstrong’s famous words “one small step for man, one giant leap for mankind”.

The moon landing video features clips of Neil Armstrong, the American flag and the desolate Moon landscape.

Black Hole Destroying a StarWatch this amazing animation of a black hole destroying a star in the deepest reaches of space.

Not even a huge star such as the one seen in this video can escape the incredible gravitational pull of a black hole.

the solar system songI am the Sun.I’m a burning ball of fire.I’m very big indeed.Life on earth depends on me.I am the sun.

I am Mercury.I’m the closest planet to the sun.I’m a ball of iron — I have no moons.I am Mercury.

I am Venus.I’m the same size as the Earthbut I spin the other way and much more slowly.I have no water — I am Venus.

I am the Earth.The place where we all live.There is land and lots of sea so I look blue.I have a moon.I am the Earth.

I am Mars.I’m a rocky, red planet.My mountains are the highest in our solar system.I have 2 moons.I am Mars.

I am Jupiter.I’m a gas giant.I’m the biggest and I spin the fastest.I have the biggest moon.I am Jupiter.

I am Saturn.I’m a gas giant.My rings are made of ice.Titan is my biggest moon.I am Saturn.

I am Uranus.I’m an icy gas giant.I’m the coldest planet in our solar system.And I have rings made of dust.I am Uranus.

I am Neptune.I’m an icy gas giant.I’m the farthest planet from the sun.I have many storms.I am Neptune.

We are The Solar System.We are The Solar System.

birth of the solar system

Birth of the Solar System

Watch this excellent National Geographic video which details how the solar system was born using breathtaking animations. Learn how the Sun was born billions of years ago and started the process of nuclear fusion, releasing photons as it combined hydrogen atoms to form helium. Stars such as the Sun release huge amounts of energy over the billions of years they exist and their lifetime often ends in a spectacular explosion, the intense energy helping form new elements. The creation of our solar system was part of a series of violent explosions and intense radiation going all the way back to the Big Bang that most scientists agree created the Universe.

the sun

Makes life on our planet possible by giving us great amounts of light and heat.

Contains about 98% of the mass of the entire Solar System.

Is just a medium sized star (yellow dwarf). It is about 1.4 million kilometers in diameter.
