Aurora Australis

Have you ever witnessed nature's light show dancing across the night sky?This colourful display is known as ‘The Southern Lights’.  What causes this spectacular illumination, Aurora Australis?

The Southern Lights starts off with a solar flare millions of miles away from Earth.  A solar flare is when the sun ejects a cloud of electrons, ions and atoms into space.  The electrons, ions and atoms then travel towards Earth.

Earth has a magnetic field, this magnetic field acts like an invisible shield.  When  the particles  from the solar flare hit Earth’s magnetic field they follow the path of the magnetic field to the North and South Poles. They then accelerate and collide with with other particles and release energy in the form of light.

The spectacular light show Aurora Australis  doesn’t only happen in the south it happens in the north where it’s called Aurora Borealis.

How Are Black Holes Formed

A black hole is a massive object. Nothing can escape its gravitational pull.  A black hole disguises itself in space. If anything goes into a black hole there is no possible chance of escaping its gravitational pull especially not with the technology we have today .

A black hole starts off with a star twenty times the size of the sun.  A star this size has a huge amount of gravity, at the core of the star it pushes energy outwards to keep the star stable.  When the star runs out of fuel it can’t release energy.  Gravity wins!  A huge explosion happens, this is called a gamma ray.  A gamma ray is when a huge star twenty times the size of the sun is no longer stable and gravity crushes it.

In a millisecond the core shrinks to a fraction of its original size.  Then a baby black hole is formed.  The baby black hole then eats all that it can until it coughs.  This  causes  a major explosion which blows up what's left of the star.  Now it devours particles and and meteorites.  Did you know that Earth’s magnetic field is the only thing stopping Earth from being sucked up by a black hole.

A black hole is a really big danger to earth and everything living on it. A black hole is a giant vacuum that can suck up a whole planet.  The closest black hole to earth is 7800 light years away from Earth.  The biggest black hole is 40 billion times the size of Earth’s sun.
