1 00:00:21,950 --> 00:00:19,490 the cosmic infrared background 2 00:00:23,960 --> 00:00:21,960 experiment shortened to cyber is a 3 00:00:26,150 --> 00:00:23,970 series of four rocket measurements 4 00:00:30,550 --> 00:00:26,160 designed to improve our understanding of 5 00:00:35,060 --> 00:00:33,380 cyber has measured unexpectedly bright 6 00:00:37,549 --> 00:00:35,070 irregularities in the glow at the 7 00:00:39,319 --> 00:00:37,559 shortest infrared wavelengths which we 8 00:00:42,020 --> 00:00:39,329 interpret to be due to stars tossed out 9 00:00:44,690 --> 00:00:42,030 during the assembly of galaxies during 10 00:00:46,069 --> 00:00:44,700 this process some stars are flung far 11 00:00:47,450 --> 00:00:46,079 from the galaxies and are no longer 12 00:00:49,400 --> 00:00:47,460 strongly associated with them as 13 00:00:52,729 --> 00:00:49,410 highlighted by the solo movie yellow 14 00:00:55,580 --> 00:00:52,739 regions as the two galaxies continue to 15 00:00:57,920 --> 00:00:55,590 interact forming a larger galaxy more 16 00:01:01,819 --> 00:00:57,930 stars are lost and regions far from the 17 00:01:03,889 --> 00:01:01,829 host galaxies begin to light up over 18 00:01:06,410 --> 00:01:03,899 time the lost stars move on random 19 00:01:08,990 --> 00:01:06,420 orbits and fill in a huge halo around 20 00:01:11,570 --> 00:01:09,000 the central galaxy as we zoom out 21 00:01:13,700 --> 00:01:11,580 showing more galaxies we see that a 22 00:01:16,640 --> 00:01:13,710 similar process occurs throughout the 23 00:01:18,679 --> 00:01:16,650 universe in the cyber result we isolate 24 00:01:20,600 --> 00:01:18,689 the large faint halo light which appears 25 00:01:23,990 --> 00:01:20,610 in the real data as fluctuations of 26 00:01:25,520 --> 00:01:24,000 large scales these images suggest there 27 00:01:27,740 --> 00:01:25,530 may be as much light in the vast spaces 28 00:01:29,270 --> 00:01:27,750 between galaxies as in the galaxies
