Wonders of the Solar System — S01E03 — The Thin Blue Line

00:00:09 We live on a world of wonders.

00:01:56 But, remarkably, in the frozen wastes of the solar system...

00:04:56 Whoo-hoo!

00:07:36 The thin blue line makes the Earth the wonderfully diverse place it is.

00:10:24 You can see that because it's really easy for me to pick a rock up off the ground,

00:12:12 CREW LAUGH

00:14:26 ..Mercury.

00:16:41 This is Saskatchewan in western Canada and it is a cold place to be in November.

00:18:44 In just five seconds, it's almost all over and, of course,

00:20:52 lit up the sky over here and then, quite literally,

00:23:19 living things, like me, to evolve

00:25:39 On Earth, greenhouse gases are essential to our survival.

00:28:23 ..a space rover, named Opportunity.

00:30:37 Mars' atmosphere was significantly denser,

00:33:28 Although Mars has lost most of its atmosphere,

00:36:33 and so more warm, moist air is sucked in and that fuels the rise of the storm.

00:39:20 What we have found on this small world is simply astonishing.

00:42:25 then what's going to happen...

00:45:29 These are the actual images taken by Huygens

00:47:22 disputed the interpretation of a river channel.

00:50:28 when this picture was taken,

00:53:15 in the presence of oxygen, then you get what chemists call an exothermic reaction.

00:55:54 and they would fall to the ground as slowly as snowflakes fall onto the surface of our own planet.
