Narrator: This is Science Today. The best images
yet of Saturn's moon Titan have been captured by astrophysicists
at the Lawrence Livermore National Laboratory and
the University of California. These images, taken
by the Keck telescope, utilized a special computer
processing technique that provided higher resolution.
Lab physicist Bruce Macintosh says this enabled researchers
to see past a hazy smog that had long obscured Titan
and confirmed a previous theory its surface features
a sea - not of water, but an oily black substance
made up of liquid hydrocarbons.
Macintosh: Which makes it the first open body
of liquid that's been seen on any planet in the solar
system, other than the Earth.
Narrator: In fact, Macintosh says Titan is
a lot like the Earth was four billion years ago.
Macintosh: So, in some sense, it's a laboratory
for studying what conditions were like on Earth before
life formed. On Titan, they're not likely to lead
to life. It's way to cold. There's no liquid water
there's just these other liquids. But nonetheless,
it can provide an analogy for what conditions were
like on the Earth four billion years ago. e is trying
to treat a problem as opposed to taking healthy people
and trying to do better.
