1 00:00:00,000 --> 00:00:04,000 [Music throughout] 2 00:00:04,000 --> 00:00:08,000 Meet SGR 1830-0645, 3 00:00:08,000 --> 00:00:12,000 a newfound magnetar 13,000 light-years away 4 00:00:12,000 --> 00:00:16,000 that’s done something never seen before. 5 00:00:16,000 --> 00:00:20,000 It’s a neutron star – 6 00:00:20,000 --> 00:00:24,000 the crushed core of an exploded sun – 7 00:00:24,000 --> 00:00:28,000 with a superstrong magnetic field. 8 00:00:28,000 --> 00:00:32,000 In October 2020, it suddenly became much brighter in X-rays. 9 00:00:32,000 --> 00:00:36,000 NASA’s NICER telescope 10 00:00:36,000 --> 00:00:40,000 on the International Space Station monitored the outburst 11 00:00:40,000 --> 00:00:44,000 for more than a month. 12 00:00:44,000 --> 00:00:48,000 The X-ray emission showed a triple-peak pattern 13 00:00:48,000 --> 00:00:52,000 repeating every 10.4 seconds as the magnetar spun around. 14 00:00:52,000 --> 00:00:56,000 The peaks came as 15 00:00:56,000 --> 00:01:00,000 three surface hot spots rotated into our view. 16 00:01:00,000 --> 00:01:04,000 music 17 00:01:04,000 --> 00:01:08,000 NICER tracked these spots 18 00:01:08,000 --> 00:01:12,000 as they drifted across the star and changed size. 19 00:01:12,000 --> 00:01:16,000 Two of them even merged – a behavior not seen before. 20 00:01:16,000 --> 00:01:20,000 music 21 00:01:20,000 --> 00:01:24,000 music 22 00:01:24,000 --> 00:01:28,000 Scientists think the spots arose when sudden changes 23 00:01:28,000 --> 00:01:32,000 in the magnetar’s crust disturbed the magnetic field. 24 00:01:32,000 --> 00:01:36,000 music 25 00:01:36,000 --> 00:01:40,000 This released energy 26 00:01:40,000 --> 00:01:44,000 that produced the spots, as well as dozens of powerful X-ray bursts. 27 00:01:44,000 --> 00:01:48,000 music 28 00:01:48,000 --> 00:01:52,000 music 29 00:01:52,000 --> 00:01:56,000 NICER’s near-daily observations 30 00:01:56,000 --> 00:02:00,000 of the SGR 1830 outburst made this finding possible. 31 00:02:00,000 --> 00:02:04,000 music 32 00:02:04,000 --> 00:02:11,430 music fades 33 00:02:11,430 --> 00:02:11,435 NASA
