Colours of the sky 🌌 The aurora borealis are caused by solar wind interacting with the Earth's magnetic field and atmosphere. The different colours are caused by the different gases in our atmosphere: oxygen creates greens while nitrogen creates purples, blues and pinks. #EarthCapture by @vincentledvina . . . . #bbcearth #northernlights #aurora #auroraborealis #sky #nightphotography #landscape #landscapephotography #beautifullandscape #nationalpark #outdoors #wildoutdoors #naturephotography #nature #naturelovers #earth #earthlovers
