The sun was caught on camera, ripping apart a structure 3 00:00:08,230 --> 00:00:12,370 that was about to erupt. Didn't catch it? Let's watch again. 4 00:00:12,390 --> 00:00:16,560 A structure began rising from the surface, gaining energy as it lifted. 5 00:00:16,580 --> 00:00:20,680 But then nothing happened. 6 00:00:20,700 --> 00:00:24,840 This is the first time anyone had witnessed the teardown of a structure on the sun’s surface. 7 00:00:24,860 --> 00:00:28,930 Fortunately, at the time of this event, multiple spacecraft were making simultaneous observations 8 00:00:28,950 --> 00:00:33,120 in various temperatures. Scientists used 9 00:00:33,140 --> 00:00:37,190 those unique views to investigate why the eruption failed. 10 00:00:37,210 --> 00:00:41,310 The sun’s landscape is controlled by magnetic forces. 11 00:00:41,330 --> 00:00:45,500 Within this environment, there are locations where a rapid release of energy is more likely to occur. 12 00:00:45,520 --> 00:00:49,560 Known as “magnetic topology,” distinctive magnetic field lines rule 13 00:00:49,580 --> 00:00:53,750 these special areas, and they determine how or whether 14 00:00:53,770 --> 00:00:57,890 underlying structures can move outwards. 15 00:00:57,910 --> 00:01:02,100 When solar structures with opposite magnetic orientation collide, we expect to see them explosively release energy 16 00:01:02,120 --> 00:01:06,180 yielding a flare and a burst of material called a Coronal Mass Ejection. 17 00:01:06,200 --> 00:01:10,350 : However, If the magnetic structure dares 18 00:01:10,370 --> 00:01:14,450 to move into a less hospitable magnetic region, the surrounding topology 19 00:01:14,470 --> 00:01:18,590 will shred the structure effectively removing magnetic energy and preventing 20 00:01:18,610 --> 00:01:22,790 the potential eruption. 21 00:01:22,810 --> 00:01:30,950 This observation highlights how the sun's magnetic topology is a key factor in whether or not an eruption is successful 22 00:01:30,970 --> 00:01:35,140 tone 23 00:01:35,160 --> 00:01:39,200 tone 24 00:01:39,220 --> 00:01:47,321 beeping
