📚 Aurora, noun. 🔉 /ɔːˈrɔːrə/ 🇬🇧 ❓ Definition: A natural electrical phenomenon characterized by the appearance of streamers of reddish or greenish light in the sky, especially near the northern or southern magnetic pole. The effect is caused by the interaction of charged particles from the sun with atoms in the upper atmosphere. In northern and southern regions it is respectively called aurora borealis or Northern Lights and aurora australis or Southern Lights. ❗️ Examples: 1. The Hubble Space Telescope has spotted auroras near the poles of both Saturn and Jupiter. 2. Gaps in the magnetosphere also allow for one of Earth's most beautiful, eerie phenomena: the aurora borealis, or northern lights. 3. Bound to the Earth, our only naturally occurring experience with space weather comes from what we can see with our eyes: eclipses, comets, auroras, and sunspots. ━━━━━━━━━━━━━ 🌀 @cambridge_dic
