1 00:00:00,000 --> 00:00:04,030 music 2 00:00:04,050 --> 00:00:08,050 3 00:00:08,070 --> 00:00:12,130 On March 29, 2014 4 00:00:12,150 --> 00:00:16,190 an X-class flare burst off the sun and vaulted into history. 5 00:00:16,210 --> 00:00:20,260 as the best observed flare of all time. 6 00:00:20,280 --> 00:00:24,280 The flare was witnessed by four different NASA observatories and one ground-based observatory. 7 00:00:24,300 --> 00:00:28,330 Each telescope captures a different aspect of the flare at a different 8 00:00:28,350 --> 00:00:32,380 height off the sun's surface. Working together, NASA's 9 00:00:32,400 --> 00:00:36,440 Heliophysics Fleet will help scientists better understand what sets off these 10 00:00:36,460 --> 00:00:40,590 large explosions on the sun. 11 00:00:40,610 --> 00:00:44,670 These images were taken using NASA's Solar Dynamics Observatory, or SDO. 12 00:00:44,690 --> 00:00:48,700 It specializes in capturing images of the entire sun at once. 13 00:00:48,720 --> 00:00:52,710 A close up shot captures some detail, but not at extremely high resolution. 14 00:00:52,730 --> 00:00:56,730 IRIS watches a range of layers in the sun's 15 00:00:56,750 --> 00:01:00,780 lower atmosphere. IRIS follows a well-planned schedule to 16 00:01:00,800 --> 00:01:04,810 observe small areas on the sun in high resolution. 17 00:01:04,830 --> 00:01:08,830 It was fortuitously pointed on this active region of the sun, in the hopes of catching a flare. 18 00:01:08,850 --> 00:01:12,870 This is the first X-class flare seen by the spacecraft. 19 00:01:12,890 --> 00:01:16,890 The RHESSI spacecraft can only see material at extreme temperatures. 20 00:01:16,910 --> 00:01:20,950 on the sun. To RHESSI, a flare looks like three pockets of 21 00:01:20,970 --> 00:01:24,990 heat in a triangle formation. There are two points on the bottom, 22 00:01:25,010 --> 00:01:29,010 showing foot points, and a third at the top of the flare. 23 00:01:29,030 --> 00:01:33,060 The Japan Aerospace Exploration Agency's and NASA's Hinode 24 00:01:33,080 --> 00:01:37,110 shows a series of layers in the sun's atmosphere. The images from Hinode's 25 00:01:37,130 --> 00:01:41,140 x-ray telescope show how material progresses from the lowest part of the 26 00:01:41,160 --> 00:01:45,170 atmosphere, called the chromosphere, upward through the heart of the flare, 27 00:01:45,190 --> 00:01:49,210 up to over three thousand miles above the surface. 28 00:01:49,230 --> 00:01:53,270 These images were captured by the National Solar Observatory's 29 00:01:53,290 --> 00:01:57,330 Dunn Solar Telescope in New Mexico. 30 00:01:57,350 --> 00:02:01,380 The telescope can watch only a small area at once, but it provides much higher resolution each area. 31 00:02:01,400 --> 00:02:05,440 The March 29th flare fortunately coincided with the best time of day 32 00:02:05,460 --> 00:02:09,510 for viewing from the ground. 33 00:02:09,530 --> 00:02:13,550 When combined, this comprehensive of one single flare will shed light on 34 00:02:13,570 --> 00:02:17,660 many future discoveries. 35 00:02:17,680 --> 00:02:21,710 music 36 00:02:21,730 --> 00:02:30,564 beeping
