The document discusses the amazing universe. It defines the universe as a space filled with matter and dark energy that is causing expansion. The universe likely began with the Big Bang around 13.8 billion years ago. It contains stars, planets, black holes, nebulae, asteroids belts, and moons. The universe remains mysterious but houses everything needed to support life.

THE AMAZING UNIVERSE Raven Goodwin Year 5 2014
Prologue • The universe is ever-expanding and holds millions of secrets. It contains the world we live in, the sun we use for light, but also holds the millions of other stars, planets, black holes and other fantastic examples of matter and energy. The Universe is easily imagined by scientists.
What is the Universe? • The universe is an unknown-shaped space filled with matter and a strange cosmic energy called dark energy, which makes the universe expand. Scientists do not know what this is, or if it really exists, but if there wasn`t anything to fill the non-matter areas of the universe, the universe would not exist at all.
How did the universe begin? • The universe we now live in was possibly created by a constructive and radiative event called the Big Bang. It was probably created by the collapsion of a previous Universe, which was then compressed to the size of a single atom, and that atom became so heavy it collapsed upon itself and created a semi- nuclear explosion of extreme proportions.
What is a star? • A star is a ball of compressed hydrogen that sometimes has planets orbiting around it. It can grow to almost 4 times its mass as a supergiant, and die in a supernova that forms into a black hole or neutron star, or it can die as a planetary nebula and then become a white dwarf. They are created in nebulae.
What is a black hole? • Black holes are the scientific explanation of a region of space with gravity so strong nothing can escape. In the center of a black hole is the singularity, the mass of the dead star compressed to a point of infinite density and gravity and zero size. The event horizon is the barrier of gravitational pull at which the speed of possible escape is the speed of light. They form from supernovae.
What is a planet? • Planets are large chunks of rock formed from meteoroids, and are always found in orbit of a star. They can also be made of gases,and each one has a core made of different metals.
What is a nebula? • A nebula is a giant cloud of dust and gas that collects to form stars.Some are formed from dying stars, while others are formed from space debris.They can sometimes be seen as ‘stars’ if they`re visible, but most need to be sighted by a telescope.
What is an asteroid belt? • An asteroid belt is a large ring of space rocks that can form small or medium meteoroids which might become small moons, or natural satellites. The one around our solar system is called the Kuiper Belt.
What is a moon? • Moons, or natural satellites, orbit a planet like a planet orbits a star. Some planets have lots of moons, some have only a few, but some have none at all. Most moon are in fact meteoroids trapped in orbit by the gravity of the planet.
Epilogue • The matter inside the Universe is fascinating in many ways and reveals much about the past, present and future. Meanwhile, the universe is much of a mystery itself. It houses everything that we need to survive, all in one place.
