The aurora borealis – otherwise known as the northern lights – is a vivid demonstration of the Earth’s magnetic field interacting with charged particles from the sun. It’s also beautiful, and worth braving a cold night out when visiting the high northern (or southern) latitudes.
What makes aurora so special?
What causes the different colours in the aurora? Different gases give off different colours when they are heated. The same process is also taking place in the aurora. The two primary gases in the Earth’s atmosphere are nitrogen and oxygen, and these elements give off different colours during an aurora display.
What makes aurora beautiful?
The reason that the aurora appears in so many colors is that our atmosphere is made up of many different compounds, such as Oxygen and Nitrogen, among others. When the charged particles that come from the sun hit the atoms and molecules of Earth’s atmosphere, they excite those atoms, which then give off light.
What does aurora symbolize?
Symbolism and Importance of Aurora
She symbolized new beginnings and the opportunities that the new day offers. Today, her name is present in the stunning aurora borealis. People believe that these magical colors and light effects come from Aurora’s mantle as she rides across the sky.
Is aurora unique to Earth?
The aurora isn’t unique to Earth. Some other worlds in our Solar System, such as Saturn and Jupiter, have magnetic fields too. Solar wind particles can collide with them just as happens with Earth!
What happens if you touch the Northern Lights?
The aurora is emitted between 90 and 150 km in altitude (i.e. mostly above the ‘official’ boundary of space, 100 km), so ungloving your hand inside an aurora would likely be fatal (unless a fellow astronaut immediately reattaches your glove and repressurizes your suit).
How often do auroras happen?
“Active periods are typically about 30 minutes long and occur every two hours, if the activity is high. The aurora is a sporadic phenomenon, occurring randomly for short periods or perhaps not at all.”
What is aurora night?
The northern lights, one of several astronomical phenomena called polar lights (aurora polaris), are shafts or curtains of colored light visible on occasion in the night sky. Aurora borealis – the Northern Lights.
Are auroras same as Northern Lights?
The northern lights, or aurora borealis, are a spectacular, colourful display of light commonly seen in the night sky in the northern hemisphere. Auroras in the southern hemisphere are known as the southern lights, or aurora australis.
How auroras are formed?
In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth’s atmosphere. The energy released during these collisions causes a colorful glowing halo around the poles—an aurora.
How rare is the name aurora?
According to Social Security Administration data, Aurora has been consistently popular, remaining in the top 50 since 2017, and in the top 100 since 2015 after jumping from the 488 spot in 2000. However, it is the 16th most popular name on FamilyEducation.com.

Is an aurora harmful to humans?
The Northern Lights occur so high up in the atmosphere that they don’t pose any threat to people watching them from the ground. The aurora itself is not harmful to humans but the electrically charged particles produced could have some potentially negative effects to infrastructure and technology.
Why are the Northern Lights bad?
The solar particles that cause the Northern Lights can alter the Earth’s magnetic field, producing interruptions in satellites, compasses, and power plants. These are the most common consequences of the Northern Lights.
Who was the goddess aurora?
Aurōra (Latin: [au̯ˈroːra]) is the Latin word for dawn, and the goddess of dawn in Roman mythology and Latin poetry. Like Greek Eos and Rigvedic Ushas, Aurōra continues the name of an earlier Indo-European dawn goddess, Hausos.

What is the rarest northern light color?
The most common auroral color, a pale yellowish-green, is produced by oxygen molecules located about 60 miles above the earth. Rare, all-red auroras are produced by high-altitude oxygen, at heights of up to 200 miles.
Can you fly through aurora?
High above our planet, astronauts onboard the International Space Station (ISS) have been enjoying an up-close view of auroras outside their windows as the ISS flys through geomagnetic storms. “We can actually fly into the auroras,” says eye-witness Don Pettit, a Flight Engineer for ISS Expedition 30.
Do auroras happen every night?
Auroras happen in every month but because they’re impossible to see against the super-light late night summer skies far up north, our trips to see them tend to take place when the night skies are properly dark.
What do the Northern Lights look like to the human eye?
Simply put, most auroras are green. That would be the shortest and scientifically correct answer, (there are other colours of the aurora but green is the most commonly observed and relevant colour to this question). However, it doesn’t always appear green to our eyes.
