The Beauty of the Sky: Aurora - A Sky Tour 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. Most auroras happen about 97-1,000 kilometers (60-620 miles) above the Earth's surface. #shorts #aurora #naturalbeauty #naturalphenomena #naturalphenomenon #naturephotography #naturelovers #naturalwonders #mindblowing #nature The most active auroras happen when the solar wind is the strongest. The solar wind is usually fairly constant, but solar weather-the heating and cooling of different parts of the sun-can change daily. Solar weather is often measured in sunspots. Sunspots are the coldest part of the sun and appear as dark blobs on its white-hot surface. Solar flares and coronal mass ejections are associated with sunspots. Solar flares and coronal mass ejections are sudden, extra bursts of energy in the solar wind. Sunspot activity is tracked over an 11-year cycle. Bright, consistent auroras are most visible during the height of sunspot activity.
