At 00:00:19,480, Character said: There's something
out there in the darkness.

2
At 00:00:26,560, Character said: A world with no name.

3
00:00:32,80 --> At 00:00:34,880, Character said: ..and probably pink.

5
At 00:00:40,200, Character said: We don't know
where it came from

6
00:00:42,00 --> At 00:00:45,520, Character said: But we do know it's not alone.

8
At 00:00:50,200, Character said: It's a dwarf planet,
only discovered in 2018.

9
At 00:01:02,760, Character said: Now, you might reasonably ask,

10
At 00:01:04,840, Character said: how could thousands
of astronomers,

11
At 00:01:06,880, Character said: both amateur and professional,

12
At 00:01:08,520, Character said: miss a world that is pink
and 400km across?

13
At 00:01:13,360, Character said: Well, the answer
might lie in its nickname,

14
At 00:01:17,520, Character said: which is FarFarOut,

15
00:01:20,00 --> At 00:01:26,280, Character said: You might have thought
of the solar system as the sun,

17
At 00:01:28,960, Character said: and then all the planets lined
up, all the way out to Pluto,

18
At 00:01:42,720, Character said: This is a journey to
the least explored regions

20
At 00:01:45,480, Character said: of our solar system...

21
At 00:01:58,200, Character said: ... Visit frozen worlds

23
At 00:01:59,840, Character said: that we're discovering
beyond Pluto...

24
At 00:02:04,720, Character said: ..and reveal
a vast hidden kingdom

25
At 00:02:07,720, Character said: that even our most powerful
telescopes can't see...

26
At 00:02:11,920, Character said: ...lost...

27
At 00:02:15,280, Character said: ...In the dark.

28
At 00:02:48,560, Character said: It was the sound
that most people noticed.

29
At 00:02:51,640, Character said: (RUMBLING BOOM)

30
00:02:58,00 --> At 00:03:12,760, Character said: a rock tore through
the atmosphere...

33
At 00:03:33,240, Character said: A visitor from a distant realm.

36
At 00:03:51,840, Character said: On 28th February 2021,
a rock from space landed there,

37
At 00:03:58,280, Character said: on this driveway,

38
At 00:03:59,920, Character said: and it shattered
into hundreds of pieces.

39
At 00:04:02,240, Character said: Most of it went onto the lawn,

40
At 00:04:06,120, Character said: and the indentation
in the driveway that was here

42
At 00:04:09,640, Character said: is now in
the Natural History Museum.

43
At 00:04:12,280, Character said: And here is a piece
of that rock.

44
At 00:04:16,400, Character said: And you see that it's
very dark. It's almost black,

45
At 00:04:21,720, Character said: very different to the rocks

46
At 00:04:23,720, Character said: that you find naturally
around here.

47
At 00:04:25,520, Character said: So the question is, other than
the rather nonspecific

48
00:04:29,40 --> 00:04:31,00
"it came from space",

49
At 00:04:31,120, Character said: what exactly is this and where
exactly did it come from?

50
At 00:04:41,320, Character said: The cows werent the only ones
watching that night.

51
At 00:04:47,840, Character said: Doorbell and CCTV cameras
never sleep.

52
At 00:04:54,800, Character said: A network of specialist meteor
cameras also captured it.

53
At 00:05:12,120, Character said: ...back over the skies
of England...

55
At 00:05:25,640, Character said: ... past Mars...

57
At 00:05:32,240, Character said: ...and into the darkness.

58
At 00:05:37,240, Character said: In between Mars and Jupiter...

59
At 00:05:41,240, Character said: .. lies a realm
of rocky worlds.

60
At 00:05:45,880, Character said: This is where
that rock came from.

61
At 00:05:50,920, Character said: The asteroid belt.

62
At 00:05:56,120, Character said: Asteroids are rubble
left over from the formation

63
00:05:59,40 --> At 00:06:02,120, Character said: The remnants of planets
that never were.

65
At 00:06:06,480, Character said: It's thought there are at least
a million out here,

66
At 00:06:09,760, Character said: so dark they're incredibly
difficult to see.

67
At 00:06:16,560, Character said: But asteroids don't always stay
in the asteroid belt.

68
At 00:06:21,880, Character said: (RUMBLING EXPLOSION)

69
00:06:26,40 --> At 00:06:32,200, Character said: ... causing fragments,
big and small,

71
At 00:06:34,600, Character said: to be lost from the belt.

72
At 00:06:56,600, Character said: ...[ncluding...our own.

74
At 00:07:16,920, Character said: ...but only one has stayed
to explore the region itself.

77
At 00:07:26,800, Character said: Most asteroids are like
misshapen boulders...

78
At 00:07:32,280, Character said: ...but one stands out
from the rest...

79
At 00:07:42,200, Character said: and almost perfectly spherical.

81
At 00:07:48,600, Character said: Dawn's target world.

82
00:07:56,00 --> At 00:07:59,400, Character said: like its fellow asteroids.

84
00:08:03,00 --> At 00:08:29,600, Character said: Now, there is another world
in the solar system

88
At 00:08:31,800, Character said: where white crystals form
on the surface.

89
At 00:08:35,640, Character said: It's here, it's Earth.

90
At 00:08:37,640, Character said: This is a mountain composed
almost entirely of salt.

91
At 00:08:41,280, Character said: It's mainly sodium chloride -
actually, table salt -

92
At 00:08:46,160, Character said: and potassium in there,

94
At 00:08:49,120, Character said: This is enormous.

96
At 00:08:50,720, Character said: It extends hundreds of metres
down into the ground.

97
At 00:08:58,120, Character said: this was the Atlantic Ocean.

100
At 00:09:04,120, Character said: evaporated away,
and left the salt behind.

102
At 00:09:06,680, Character said: And then plate tectonics
raised the ground up

103
At 00:09:36,480, Character said: Now, salt crystals like this

105
At 00:09:38,400, Character said: only form in the presence
of liquid water.

106
At 00:09:45,200, Character said: In this case,
it was the Atlantic Ocean.

107
At 00:09:48,360, Character said: That raises
an intriguing question.

108
At 00:09:50,920, Character said: Are those crystal deposits
on the surface of Ceres salt?

109
At 00:09:55,960, Character said: And, if so, does that imply

110
At 00:09:58,400, Character said: there was once an ocean
on Ceres?

111
At 00:10:07,560, Character said: Dawn entered
into a close orbit.

112
At 00:10:16,920, Character said: And by measuring sunlight

113
At 00:10:18,520, Character said: reflected off
the crystal deposits,

114
At 00:10:21,280, Character said: it could determine
what they're made of.

115
At 00:10:25,640, Character said: Sodium carbonate.

116
00:10:29,00 --> At 00:10:47,440, Character said: Orbiting just 35km
from the surface,

119
At 00:10:50,720, Character said: Dawn found another clue

120
At 00:10:52,880, Character said: that suggests an ocean
may still be there today.

121
At 00:11:03,280, Character said: It detected a different type
of salt crystal

122
At 00:11:06,760, Character said: that's only been found
in one other place

123
At 00:11:09,680, Character said: in the solar system.

124
At 00:11:19,240, Character said: When saltwater evaporates,

125
00:11:21,40 --> At 00:11:23,280, Character said: salt crystals - essentially
sodium and chlorine ions

127
00:11:27,00 --> At 00:11:30,520, Character said: But under the right conditions,
when it's very cold,

129
At 00:11:39,160, Character said: It's called a hydrohalite.

132
At 00:11:40,880, Character said: Essentially, water molecules
are incorporated

133
At 00:11:43,880, Character said: into the crystal lattice.

134
At 00:11:45,840, Character said: Now, we see hydrohalites
here on Earth.

135
At 00:11:48,240, Character said: But the fact that we also
see them on Ceres

136
At 00:11:50,840, Character said: presents a mystery,

137
At 00:11:52,840, Character said: because hydrohalites
are unstable in a vacuum.

138
At 00:11:56,760, Character said: It's been calculated

139
At 00:11:58,320, Character said: they should only last
around 100 years

140
00:12:01,80 --> At 00:12:02,680, Character said: before the water escapes
out into space.
