OF THE RINGED PLANET.

HE FINDS A MOON.

ASTRONOMERS LATER
NAME IT IAPETUS

AFTER ONE OF THE TITANS
FROM GREEK MYTHOLOGY.

BY THE LAWS OF PHYSICS,

THAT WE KNOW OF ANYWAY,
MOONS DON'T DO THAT,

WHAT IT WAS.

Narrator: CASSINI COMES UP WITH
A THEORY TO SOLVE THE MYSTERY.

HE HAD ONE IDEA.

THE IDEA WAS THAT ONE SIDE
OF THE MOON WAS BRIGHT,

AND THE OTHER SIDE
OF THE MOON WAS DARK.

WHEN IT WAS COMING TOWARDS YOU,
YOU COULD SEE IT.

IT WAS NICE AND BRIGHT.

MOON'S GOING AWAY,
YOU COULDN'T SEE IT.

BUT HOW COULD THAT BE?

NO PLANET IS LIKE THAT.
NO MOON IS LIKE THAT.

Man: AND LIFT-OFF
OF THE CASSINI SPACECRAFT

Narrator: CASSINI'S THEORY

REMAINS UNTESTED FOR
MORE THAN 300 YEARS.

IN 1997, NASA LAUNCHES A PROBE

TOWARDS SATURN NAMED
AFTER THE GREAT ASTRONOMER.

CASSINI CARRYS THE MOST
SOPHISTICATED SUITE

OF SCIENTIFIC INSTRUMENTS
EVER TAKEN

INTO THE OUTER SOLAR SYSTEM.

Narrator:
WHEN THE PROBE FLIES BY IAPETUS,

IT SENDS BACK
HIGH-DEFINITION IMAGES...

THAT REVEAL SOMETHING
COMPLETELY UNEXPECTED.

WHAT YOU SEE
IS THIS RIGID MATERIAL

GOING AROUND THE EQUATOR
OF THE MOON.

IT'S AN AMAZINGLY HIGH RIDGE.

IT'S ABOUT THREE TIMES
LARGER THAN EVEREST.

Narrator:
THE RIDGE IS COLOSSAL --

800 MILES LONG
AND UP TO 12 MILES HIGH.

WE'RE SEEING SOMETHING
THAT'S UNIQUE

IN THE SOLAR SYSTEM.

A GEOGRAPHICAL FEATURE

THAT BASICALLY CROSSES
THE ENTIRE OBJECT.

WHERE DOES
SUCH A LARGE, COHERED,

BEAUTIFUL STRUCTURE COME FROM?

HOW IS IT CREATED?

Narrator: ASTRONOMERS STRUGGLE

TO EXPLAIN THE PRESENCE
OF THE MOUNTAINOUS RIDGE

ON A WORLD THAT SHOULD NOT
BE GEOLOGICALLY ACTIVE.

THE BEST THEORY
WE HAVE RIGHT NOW

IS THAT SOMETHING CAME IN

AND IMPACTED
THE SURFACE OF IAPETUS.

[ EXPLOSION ]

AN ENORMOUS RING OF DEBRIS
SPRUNG UP AROUND THE PLANET.

THIS RING CIRCLED AROUND IAPETUS
AND SPREAD ITSELF OUT,

BUT EVENTUALLY, IT WAS DRAWN
BACK DOWN ONTO THE PLANET,

CREATING THIS RING-LIKE
STRUCTURE AT ITS EQUATOR.

Narrator: BUT THE CASSINI DATA
OFFERS NO SUPPORTING EVIDENCE

FOR THE THEORY THAT AN IMPACT
CREATED THE RIDGE ON IAPETUS.

WE'VE BEEN IN ORBIT NOW
FOR A LONG TIME,

AND WE STILL REALLY DON'T KNOW
WHAT CAUSES THIS RIDGE.

IT MAY BE ONE OF THOSE MYSTERIES

THAT, YOU KNOW, STAYS WITH US
EVEN AFTER CASSINI IS OVER.

Narrator: THE IMAGES FROM
THE PROBE RAISE A NEW MYSTERY,

BUT THEY ALSO OFFER AN ANSWER
TO AN OLD ONE.

THEY CONFIRMED THAT, YES,
IN FACT, IAPETUS HAS TWO SIDES.

IT HAS A LIGHT SIDE
AND A DARK SIDE.

THE SURFACE OF THE LIGHT SIDE
IS BRIGHT, SHINING ICE,

BUT THE OTHER DARK SIDE
IS COVERED

IN A STRANGE MATERIAL
OF UNKNOWN ORIGIN.

OF COURSE, THE QUESTION
WAS WHERE DID

THAT DARK MATERIAL COME FROM?

Narrator: THE FIRST THEORY
SCIENTISTS CONSIDERED

IS THAT THE DARK MATERIAL
COULD BE FROM VOLCANIC ACTIVITY.

SOME PEOPLE BELIEVE

THAT INTERNAL PROCESSES
CAUSED THIS --

VOLCANOES SPRAYING OUT,
UH, MATERIALS.

Narrator: BUT THE CASSINI IMAGES
SHOW NO SIGNS OF ANY VOLCANOES.

THERE'S NO VOLCANISM OR ANYTHING

OF GEOLOGICAL ACTIVITY.

THE DARK SIDE REMAINS A MYSTERY

UNTIL NASA DIRECTS THE GAZE

OF THE INFRARED
SPITZER SPACE TELESCOPE

TOWARD THE DISAPPEARING MOON.

EVEN FARTHER OUT FROM SATURN
IS A RING THAT WE CAN'T SEE,

BUT WE CAN SEE IT WITH INFRARED.

WHAT SPITZER IS SHOWING US

IS THIS ENORMOUS, VAST RING
OF DUST,

PREVIOUSLY COMPLETELY UNKNOWN.

Narrator: THE ENORMOUS RING

SURROUNDS ONE
OF SATURN'S LESSER KNOWN MOONS.

IT'S ACTUALLY SO THICK

THAT 20 SATURNS COULD BE
STACKED UP INSIDE OF IT.

AND INSIDE THAT RING
IS ANOTHER MOON CALLED PHOEBE.

Narrator:
PHOEBE IS AN UNUSUAL DARK COLOR

AND APPEARS
TO BE DISINTEGRATING.

PHOEBE IS VERY PECULIAR,

AND AS IT WARMS UP
FROM THE SUN'S RADIATION,

GOING AROUND SATURN,

IT'S EMITTING
ALL SORTS OF MATERIAL.

IT'S LIKE THIS OLD CAR

SPEWING OUT ALL KINDS
OF CITY DUST AS IT GOES

AND LEAVING THIS RING
OF MATERIAL AROUND SATURN.

Narrator: NASA SCIENTISTS
BELIEVE THE DISINTEGRATING MOON

IS THE MOST LIKELY SOURCE
OF THE DARK MATERIAL

COVERING ONE SIDE OF IAPETUS.

IAPETUS IS CIRCLING SATURN,
AND EVERY TIME IT GOES AROUND,

IT SMASHES INTO THIS RING
FROM PHOEBE,

AND IT'S, LIKE,
ACCUMULATING, UH, BUGS

ON THE WINDSHIELD OF A CAR,
