  "definitions": [
    "A natural light display in the Earth's sky, predominantly seen in high-latitude regions, caused by the collision of energetic charged particles with atoms and molecules in the upper atmosphere. These particles, originating from the solar wind, are guided by the Earth's magnetic field towards the poles, exciting atmospheric gases that then emit light. The colors observed depend on the type of gas and the altitude of the collision.",
    "A faint visual phenomenon associated with geomagnetic activity,\nwhich occurs mainly in the high-latitude night sky; typical\nauroras are 100 to 250 km above the ground"
