Inside the Milky Way

00:00:05 The Milky Way galaxy...

00:05:13 because their stars are contained in arms that spiral out from their centers.

00:09:34 Scutum Centaurus

00:14:53 The Eagle Nebula, with towering pillars up to four light years in size

00:18:52 and our galaxy has gas.

00:23:45 we find that all of the gases were at a common point

00:27:44 so that we can study supernovae in greater numbers

00:31:27 But from this death comes new life.

00:36:21 We're taking the Earth from the safety of home

00:40:13 we can actually see the data that we've taken

00:43:58 is that the black hole

00:48:08 in many cases are almost as old as the universe itself.

00:52:05 So these dwarf galaxies are whizzing around our galaxy.

00:56:21 If you go to more distant planets

00:59:33 So we need the dark matter.

01:04:05 But already the seeds of change are being sown.

01:07:55 So what we're looking at

01:12:07 Here we see one of the first stars in the universe.

01:15:58 When we look at these early galaxies

01:20:15 the future of the Milky Way and the Andromeda Galaxy

01:24:08 looking at the sky and seeing this spectacular image.

01:28:28 because these Jupiter-like planets are so close

01:32:10 Downtown is dangerous.

380:00:00 after the big bang.
