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.
