1 00:00:12,629 --> 00:00:09,750 certain faculty on titan is the best 2 00:00:14,230 --> 00:00:12,639 case yet of a cryovolcano in the outer 3 00:00:16,070 --> 00:00:14,240 solar system 4 00:00:17,590 --> 00:00:16,080 in fact it appears to be two 5 00:00:21,109 --> 00:00:17,600 cryovolcanoes 6 00:00:23,590 --> 00:00:21,119 separated by a low area 7 00:00:26,710 --> 00:00:23,600 where we see some sand dunes 8 00:00:28,390 --> 00:00:26,720 here we see data from radar and the 9 00:00:30,470 --> 00:00:28,400 visible and infrared mapping 10 00:00:33,030 --> 00:00:30,480 spectrometer 11 00:00:35,750 --> 00:00:33,040 this is false column to distinguish the 12 00:00:37,590 --> 00:00:35,760 different compositions of the surface so 13 00:00:39,990 --> 00:00:37,600 the green areas are what we think are 14 00:00:42,470 --> 00:00:40,000 the volcanic areas 15 00:00:44,069 --> 00:00:42,480 while the blues would be fields of sand 16 00:00:46,869 --> 00:00:44,079 dunes 17 00:00:50,630 --> 00:00:46,879 now we change the color scheme the reds 18 00:00:52,950 --> 00:00:50,640 and yellows are highs the blues are lows 19 00:00:55,750 --> 00:00:52,960 when we got the topography we see this 20 00:00:58,150 --> 00:00:55,760 tall mountain is about a thousand meters 21 00:01:00,630 --> 00:00:58,160 tall when you have a tall mountain and a 22 00:01:03,270 --> 00:01:00,640 deep crater and a low bait flow-like 23 00:01:06,070 --> 00:01:03,280 feature coming out of it then it's very 24 00:01:08,789 --> 00:01:06,080 likely to be a cryovolcano 25 00:01:11,830 --> 00:01:08,799 on earth volcanoes are formed by molten 26 00:01:14,870 --> 00:01:11,840 rock or magma that when it comes out is 27 00:01:18,149 --> 00:01:14,880 called lava on titan and 28 00:01:21,109 --> 00:01:18,159 other icy bodies such as saturn's moon 29 00:01:23,270 --> 00:01:21,119 enceladus we have cryovolcanism that is 30 00:01:25,109 --> 00:01:23,280 very cold volcanism 31 00:01:28,070 --> 00:01:25,119 and the 32 00:01:31,429 --> 00:01:28,080 material inside this body is the quotes 33 00:01:34,550 --> 00:01:31,439 magma is not molten rock is actually a 34 00:01:37,190 --> 00:01:34,560 watery mixture is water with probably 35 00:01:39,590 --> 00:01:37,200 ammonia and maybe methanol and other 36 00:01:40,390 --> 00:01:39,600 things materials being brought from the 37 00:01:43,990 --> 00:01:40,400 interior 38 00:01:45,590 --> 00:01:44,000 of the moon or the planet to the surface 39 00:01:46,950 --> 00:01:45,600 this is important for a number of 40 00:01:49,590 --> 00:01:46,960 reasons and 41 00:01:53,350 --> 00:01:49,600 one of them is that if you still have 42 00:01:56,469 --> 00:01:53,360 heat and enough heat to actually 43 00:01:59,030 --> 00:01:56,479 cause a cryovolcanism to occur 44 00:02:01,109 --> 00:01:59,040 and if you have water then those are two
