Spectrum

White light

Split into colours

Created by sunlight

Rainbows glow

Chemicals create different colours, sodium used in street lights glows yellow. Chemicals are used in fireworks, like strontium (red?) or copper green, creating different colours, blues, purples, oranges.

The reason sunlight is made up of a spectrum is because the sun is made not only of hydrogen and helium but all the chemicals in the periodic table up to iron (any chemicals beyond that can only be created in Super Novae explosions). All the chemicals in the sun glow in different colours, which is why they show up when the white light from the sun passed through a prism. If you split the spectrum further you can find dark lines, these are markers of which chemicals are present. The older the star the more chemicals. As a star gets older it starts to burn up its hydrogen and helium. New chemicals are created by atoms fusing together. That’s where new chemicals are made. When you think about it, if it wasn’t for stars burning or exploding we couldn’t exist.

Negative dawn

The bright green sky shone out beyond the white branches of the treeplynths.

Flinners sang in the plynths, making booming noises and screeches. The star rose above the horizon, deep red in the sky.

Veleno watched the dawn, Earthship Orion would be leaving soon. The journey to Betelguse had been stressful, but they had found this beautiful and bizarre planet circling the red giant star. But now it was time to leave. The return journey to earth would take centuries, but the Red Giant was going to go super nova soon. If they didn’t get a fair distance away from it in the next fifty years they would not survive.

Veleno took a few more images of the dawn. The whole star rise thing took about three Earth hours. He looked at the rising star, moving so slowly, what would it be like to stand here and see it explode? No, he could not imagine its immense effects and size. Time to leave.

Twisted sunrise

Betelguse the star is shrinking.

Fainting they say.

On the shoulder of Orion,

it’s getting fainter.

Red Giant,

stellar wonder,

obese and middle aged?

Perhaps your sides are about to split.

Red Giants can’t stay inflated.

They use up all their fuel.

Puffed up and massive.

Suddenly they can pop like a balloon.

Not enough energy to push out,

the star will fall inwards,

then boom!

Bounce out…

In a million years or so?

You might be a Supernova!

Make a Betelguse nebula.

Then Orions shoulder will flower.

And we may see an exploding star.

The first in the Milky-way since 1604.
