1 00:00:00,000 --> 00:00:07,100 Music 2 00:00:07,120 --> 00:00:09,530 Just as the sun is part of weather on Earth; 3 00:00:09,550 --> 00:00:12,310 it also affects weather in space. 4 00:00:12,330 --> 00:00:16,430 The sun creates solar wind by steadily releasing a flow of plasma particles in all 5 00:00:16,450 --> 00:00:20,570 directions around it. Sometimes the sun gives of a flash of light in x-rays. 6 00:00:20,590 --> 00:00:24,670 This is known as a solar flare. When a massive 7 00:00:24,690 --> 00:00:28,770 bursts of particles explode into space, we call it a coronal mass ejection or 8 00:00:28,790 --> 00:00:32,870 CME. When a CME is directed toward earth it hits 9 00:00:32,890 --> 00:00:36,970 the magnetosphere, the magnetic field around our planet that protects us. If the storm 10 00:00:36,990 --> 00:00:41,060 is large we may even get to enjoy a light display in the sky called the auroras. 11 00:00:41,080 --> 00:00:45,120 In space, satellites may be damaged, 12 00:00:45,140 --> 00:00:49,180 and astronauts should take cover. On earth, people do not feel any 13 00:00:49,200 --> 00:00:53,230 physical effects. You may loose electricity in some areas. Polar flights may be rerouted 14 00:00:53,250 --> 00:00:57,290 and satellite services may be disrupted. While these situations aren't 15 00:00:57,310 --> 00:01:01,330 ideal, they are rare and fixable. 16 00:01:01,350 --> 00:01:05,420 This is why we will continue to study the sun and its interactions with earth, 17 00:01:05,440 --> 00:01:09,550 and the solar system. 18 00:01:09,570 --> 00:01:13,770 beeping 19 00:01:13,790 --> 00:01:23,597 beeping
