1 00:00:16,810 --> 00:00:20,647 Okay. So the presence of ice on Mars suggests water, 2 00:00:20,730 --> 00:00:23,275 either now or sometime in the past. 3 00:00:26,027 --> 00:00:28,280 Yes. It's very exciting. 4 00:00:28,363 --> 00:00:33,451 And on Europa, the presence of an ocean below the ice is also promising 5 00:00:33,535 --> 00:00:37,747 because it means that conditions could be right for life to develop there too. 6 00:00:39,541 --> 00:00:44,337 Exactly. And there's potentially been enough time for life to evolve. 7 00:00:44,421 --> 00:00:48,758 That means Europa's definitely a place for NASA to keep researching. 8 00:00:56,641 --> 00:00:58,268 Not so fast, Snoopy. 9 00:00:58,351 --> 00:01:01,813 We haven't found life yet. Just the potential for life. We haven't found life yet. Just the potential for life. 10 00:01:01,897 --> 00:01:04,481 It's big, but it's not "root beer" big. 11 00:01:07,360 --> 00:01:08,486 Hey! 12 00:01:10,780 --> 00:01:12,532 Marcie and Franklin are right. 13 00:01:12,616 --> 00:01:17,704 But hopefully, we will discover something that's "root beer" big very soon. 14 00:01:17,787 --> 00:01:19,247 I'll check back later. 15 00:01:23,251 --> 00:01:25,837 So, where should we look next? 16 00:01:25,921 --> 00:01:29,466 What about this planet? It's about the same size as Earth. 17 00:01:33,678 --> 00:01:35,722 And the same roundness as your head. 18 00:01:39,100 --> 00:01:40,310 That's Venus, Charles. 19 00:01:40,393 --> 00:01:43,063 Named for the Roman goddess of love. 20 00:01:43,146 --> 00:01:45,148 Goddess of love? 21 00:01:45,232 --> 00:01:49,694 That sounds like the perfect place. Doesn't it, my Sweet Babboo? 22 00:01:50,612 --> 00:01:51,988 I'm not your Sweet Babboo. 23 00:01:52,822 --> 00:01:55,700 It's funny that it's named after the goddess of love 24 00:01:55,784 --> 00:01:59,621 because Venus is actually a very harsh and unpleasant place. 25 00:02:00,956 --> 00:02:02,332 Sounds like love to me. 26 00:02:03,833 --> 00:02:07,921 Valentine's Day! A chance for people to show you how much they care. 27 00:02:11,383 --> 00:02:12,884 I got something this year. 28 00:02:18,181 --> 00:02:19,641 I can't stand it. 29 00:02:23,478 --> 00:02:26,064 It's still the best valentine I ever got. 30 00:02:26,147 --> 00:02:27,190 Sorry, Charles. 31 00:02:27,274 --> 00:02:31,528 But according to my research, finding life on Venus would be very unlikely. 32 00:02:34,072 --> 00:02:38,118 I still think we should consider it. I've never been one to give up. 33 00:02:38,868 --> 00:02:39,869 Ow! 34 00:02:40,412 --> 00:02:42,455 Despite all evidence that you should. 35 00:02:45,292 --> 00:02:49,129 Marcie's right. I guess it was a pretty silly idea. 36 00:03:04,394 --> 00:03:07,314 Venus does seem like an unlikely place for life. 37 00:03:07,397 --> 00:03:08,398 For one thing, 38 00:03:08,481 --> 00:03:12,485 it's got the thickest atmosphere of all the rocky planets in the solar system. 39 00:03:33,089 --> 00:03:37,761 The thick atmosphere traps the sun's heat. So Venus is incredibly hot. 40 00:03:37,844 --> 00:03:42,432 Day-at-the-beach hot, or fresh-out-of-the-oven-apple-pie hot? 41 00:03:42,515 --> 00:03:46,937 Much hotter. Around 462 degrees Celsius. 42 00:03:47,771 --> 00:03:50,649 That's over 860 degrees Fahrenheit. 43 00:03:53,818 --> 00:03:55,820 What? I know stuff. 44 00:03:57,072 --> 00:03:59,366 Venus is also exceptionally dry. 45 00:04:07,415 --> 00:04:10,585 And don't forget the wind. It's stronger than a tornado. 46 00:04:12,796 --> 00:04:16,173 It sure doesn't sound like the kind of place we'd find life. 47 00:04:16,257 --> 00:04:19,344 It's not. Even the air is poisonous. 48 00:04:19,427 --> 00:04:23,265 Although, there is evidence that there are underground caves on Venus. 49 00:04:23,348 --> 00:04:27,561 I suppose it's possible life could exist down there. 50 00:05:09,978 --> 00:05:15,066 Of course, those caves were made by volcanoes. So they might be full of lava. 51 00:05:44,179 --> 00:05:47,390 - Well, scratch Venus off the list. - Agreed. 52 00:05:47,474 --> 00:05:51,144 It doesn't seem like the kind of place that could support life as we know it. 53 00:05:51,228 --> 00:05:54,272 Well, what about life as we don't know it? 54 00:05:54,856 --> 00:05:57,359 Don't be a blockhead, Charlie Brown. 55 00:05:58,026 --> 00:06:00,820 Actually, Charlie Brown makes a good point. Actually, Charlie Brown makes a good point. 56 00:06:00,904 --> 00:06:03,114 - He does? - I do? 57 00:06:03,198 --> 00:06:04,449 You bet. 58 00:06:04,532 --> 00:06:07,452 Part of the search for life is considering the possibility 59 00:06:07,535 --> 00:06:11,122 that life may exist in ways we don't fully comprehend yet. 60 00:06:11,206 --> 00:06:15,544 Why, even here on Earth there are examples of life we barely understand. 61 00:06:16,211 --> 00:06:19,631 From microscopic organisms living in superheated vents 62 00:06:19,714 --> 00:06:21,258 at the bottom of the ocean 63 00:06:21,341 --> 00:06:25,095 to bacteria that somehow survive in volcanic acid lakes. 64 00:06:25,762 --> 00:06:30,684 Earth is full of life that lives in extreme and unusual environments. 65 00:06:31,851 --> 00:06:35,230 So it's possible life might exist on Venus after all? 66 00:06:35,313 --> 00:06:37,232 You never know, Charlie Brown. 67 00:06:37,315 --> 00:06:41,611 There could even be tiny life forms living in Venus's atmosphere. 68 00:06:44,030 --> 00:06:45,490 Imagine that. 69 00:06:45,574 --> 00:06:49,661 Life floating above it all, surviving against the odds. 70 00:07:04,801 --> 00:07:08,054 Life as we don't know it? Who would've thought? 71 00:07:08,138 --> 00:07:10,473 Charlie Brown. That's who. 72 00:07:13,268 --> 00:07:14,895 Good ol' Charlie Brown. 73 00:07:19,274 --> 00:07:21,526 Way to go, big brother! 74 00:07:23,778 --> 00:07:25,864 Thanks, Snoopy. To life! 75 00:07:38,960 --> 00:07:40,879 There goes the solar system. 76 00:07:43,673 --> 00:07:44,883 Good grief.
