Twilight Phenomena

Rocket launches at sunset or sunrise produce a light show known as twilight phenomena. It forms when unburned fuel particles and water condense, freeze, and then expand across the upper atmosphere, leaving a trail of frozen droplets that di ffracts sunlight and produce colourful ribbons in pink, blue, green and orange that can be carried hundreds of kilometres away from the launch site.

Sir Isaac Newton (1642-1727)

He was an English physicist and mathematician who found that white light is a mixture of colours (the rainbow) and also discovered the law of gravity (supposedly after watching an apple fall from tree). His most famous book was known as principia mathematica . He was knighted in 1705 and is buried in Westminster Abbey. He was born in 1642 AD and died in 1727 AD.
