Why Aurora Has Different Colors
Here we learn what causes the different colors in the aurora borealis (northern lights) and the aurora australis (southern lights). Learn how aurora colors work. See the chemistry and physics of the northern and southern lights and how the aurora works on other planets.
Learn how the aurora gets its colors from the interactions of energetic particles and air molecules in the upper atmosphere. Explore the history, structure, and processes of the northern lights with examples and images. What determines the colors of the Northern Lights The majority of auroral displays are predominantly green for two reasons: the first of which is that the human eye detects green more readily than other colours.
Aurora colors - why they coloured differently like pink aurora ...
And these beautiful displays are different every night, varying in intensity, pattern and colour palette. So what causes the aurora colours? And why are they constantly changing? Here, we look at the science behind this breathtaking spectacle, exploring the colours of the aurora and the atmospheric gases that cause them. Learn how charged particles from the Sun excite oxygen and nitrogen atoms in Earth's atmosphere, producing different colours of light.
Discover why green is the most common colour, red is rare, and blue and magenta are possible. Aurora are caused by charged particles from the Sun colliding with Earth's atmosphere, releasing light of different colors depending on the energy and altitude of the collisions. Learn how aurorae are related to the Sun's activity, Earth's magnetic field, and the upper atmosphere.
Colorful science behind Northern lights explains why green, red, purple ...
The shifting face of Earth's light show is miraculous. A guide to the science of the aurora why it appears in different shapes and colours. Have you ever noticed the different colors in streetlights? Some are a dark yellow color while others have a blue or purplish light.
How about neon signs? They have many different colors. Streetlights and neon signs are filled with gas. When they are turned on, an applied voltage energizes electrons in the gas.

These electrons strike the gas molecules, which excites them to emit light. The. Why does the aurora change into different colors? Find out the answer in this article to learn what causes it to turn green, pink, red, violet, or white.
