1 00:00:05,630 --> 00:00:03,590 NASA's Hubble Space Telescope captured 2 00:00:09,290 --> 00:00:05,640 three separate moments in a far-off 3 00:00:11,930 --> 00:00:09,300 supernova explosion in a single snapshot 4 00:00:14,930 --> 00:00:11,940 these moments provide a unique glimpse 5 00:00:17,689 --> 00:00:14,940 into the supernova's early life 6 00:00:20,450 --> 00:00:17,699 it is quite rare to detect a supernova 7 00:00:23,810 --> 00:00:20,460 explosion at a very early stage because 8 00:00:26,689 --> 00:00:23,820 that stage is so short it only lasts for 9 00:00:28,009 --> 00:00:26,699 hours to a few days and it can be easily 10 00:00:30,769 --> 00:00:28,019 missed 11 00:00:32,930 --> 00:00:30,779 the star exploded more than 11 billion 12 00:00:35,569 --> 00:00:32,940 years ago when the universe was less 13 00:00:39,350 --> 00:00:35,579 than one-fifth of its current age of 14 00:00:41,630 --> 00:00:39,360 13.8 billion years in a single exposure 15 00:00:43,670 --> 00:00:41,640 Hubble captured the supernova's rapid 16 00:00:46,549 --> 00:00:43,680 change of color which indicates 17 00:00:49,310 --> 00:00:46,559 temperature change the early hotter 18 00:00:52,250 --> 00:00:49,320 phase appears blue as the Supernova 19 00:00:54,049 --> 00:00:52,260 cooled its light turned redder this 20 00:00:56,389 --> 00:00:54,059 detection was possible through a 21 00:00:58,970 --> 00:00:56,399 phenomenon called gravitational lensing 22 00:01:00,950 --> 00:00:58,980 as first predicted by Einstein's theory 23 00:01:03,529 --> 00:01:00,960 of general relativity 24 00:01:07,130 --> 00:01:03,539 in this case the immense gravity of the 25 00:01:08,929 --> 00:01:07,140 Galaxy cluster Abel 370 both bent and 26 00:01:10,969 --> 00:01:08,939 magnified the light from the more 27 00:01:14,450 --> 00:01:10,979 distant Supernova located behind the 28 00:01:17,149 --> 00:01:14,460 cluster like a giant Cosmic lens 29 00:01:19,010 --> 00:01:17,159 this lensing effect split and warped the 30 00:01:22,249 --> 00:01:19,020 supernova's light bending it along 31 00:01:24,530 --> 00:01:22,259 separate Pathways of varying lengths 32 00:01:27,109 --> 00:01:24,540 the different travel times between each 33 00:01:29,270 --> 00:01:27,119 path created a time delay that produced 34 00:01:31,670 --> 00:01:29,280 three distinct images of the explosion 35 00:01:35,030 --> 00:01:31,680 at different times that arrived at Earth 36 00:01:39,950 --> 00:01:37,910 this is the first detailed look at a 37 00:01:41,569 --> 00:01:39,960 supernova at such an early time of the 38 00:01:43,969 --> 00:01:41,579 universe's evolution 39 00:01:46,069 --> 00:01:43,979 the research could help scientists learn
