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
