THE AURORA BOREALIS

The aurora is caused by high-energy particles from the sun colliding with molecules in the Earth’s atmosphere. As they collide, the molecule gives off light, just like a neon sign. The colour of the light depends on the molecule being hit and how high it is. Oxygen gives off yellow-green and red light, while nitrogen usually glows purple.

But just yesterday there was a beautiful display of Northern Lights in UK. How is that even possible?

The auroras usually form in circles around the North and South Poles, because the particles coming from the sun have an electrical charge and are steered towards the poles by the Earth’s magnetic field.
Like the Earth, the sun has weather. And when the sun has a really big storm, it releases vast numbers of these charged particles. When the lights make it this far south it’s because there’s been a major solar storm. How cool is that?

There has been a beautiful display in Scotland, UK and even Jamaica and Cuba. Charged solar particles slamming into our atmosphere at thousands of miles a second make such lovely patterns. Don't you agree?

As a person that has 'see the Northern lights' written on her bucket list, that was the coolest thing ever, thank you Buzzfeed for always impressing me.
