WEBVTT FILE 1 00:00:00.020 --> 00:00:04.040 [No Audio] 2 00:00:04.060 --> 00:00:08.090 [Bwaaam] 3 00:00:08.110 --> 00:00:12.100 [Bwaaam] 4 00:00:12.120 --> 00:00:16.130 [Bwaam] When we started watching it, we 5 00:00:16.150 --> 00:00:20.170 had no idea how dynamic this system was. [Music] 6 00:00:20.190 --> 00:00:24.180 [Music] 7 00:00:24.200 --> 00:00:28.230 We still don't know what it's capable of. [Whoosh] 8 00:00:28.250 --> 00:00:32.260 [Bwaaam] The only way these readings make 9 00:00:32.280 --> 00:00:36.320 sense is if this pulsar is orbiting a star. 10 00:00:36.340 --> 00:00:40.320 We've never seen one in an orbit this long. The binary 11 00:00:40.340 --> 00:00:44.340 companion is one of the brightest stars in our galaxy, and the pulsar is going to 12 00:00:44.360 --> 00:00:48.410 pass incredibly close to it! This pulsar has been 13 00:00:48.430 --> 00:00:52.430 accelerating for the last ten years, and it's still speeding up. 14 00:00:52.450 --> 00:00:56.520 [Bwaam] 15 00:00:56.540 --> 00:01:00.550 When it passes through the companion star's disk, we're gonna see some serious 16 00:01:00.570 --> 00:01:04.600 gamma-ray emission. Fermi will be watching in 17 00:01:04.620 --> 00:01:08.660 gamma rays. It has the tools. 18 00:01:08.680 --> 00:01:12.710 [Music] 19 00:01:12.730 --> 00:01:16.760 [Music] 20 00:01:16.780 --> 00:01:20.820 There's so much we can learn from this. 21 00:01:20.840 --> 00:01:24.860 [Music] 22 00:01:24.880 --> 00:01:28.880 [Wwraum] 23 00:01:28.900 --> 00:01:32.920 We're going to need a bigger hard drive 24 00:01:32.940 --> 00:01:36.990 [Wwraum] [indistinct radio voices] 25 00:01:37.010 --> 00:01:41.030 [indistinct radio voices] 26 00:01:41.050 --> 00:01:45.100 [Beeping] 27 00:01:45.120 --> 00:01:49.150 [Beeping] 28 00:01:49.170 --> 00:01:55.762 [Beeping]
