1 00:00:00,000 --> 00:00:09,000 Hi, I'm William Jeffries with more science news you can use. 2 00:00:09,000 --> 00:00:13,000 Bet you've never seen anything like this up in the sky. 3 00:00:13,000 --> 00:00:15,000 Okay, I give up. What is it? 4 00:00:15,000 --> 00:00:19,000 It's the Aurora Borealis, or Northern Lights, nature's TV show. 5 00:00:19,000 --> 00:00:25,000 They're mostly seen in the northern and southern extremes of the Earth, someplace like Alaska. 6 00:00:25,000 --> 00:00:28,000 The solar wind brings charged particles from the sun, 7 00:00:28,000 --> 00:00:32,000 which strike gases in the Earth's atmosphere, causing the gases to glow in different colors. 8 00:00:32,000 --> 00:00:34,000 I've never seen anything like that. 9 00:00:34,000 --> 00:00:36,000 Well, in a way you have. 10 00:00:36,000 --> 00:00:40,000 The color TV screen you're looking at right now glows in bright colors 11 00:00:40,000 --> 00:00:44,000 when a charged particle touches the chemicals inside. 12 00:00:44,000 --> 00:00:49,000 So the Northern Lights are kind of like nature's TV show in the sky. 13 00:00:49,000 --> 00:00:54,000 Until next time, I'm William Jeffries with more science news you can use. 14 00:00:54,000 --> 00:00:59,000 ♪ MUSIC ♪
