How Far Away Is It 07 Planetary Nebula (1080p)

Text at In this segment of our How far away is it video book, we cover Planetary Nebula. We begin by introducing astrophotography and how it adds to what we can see through a telescope with our eyes. We use NGC 2818 to illustrate how this works. We then show a clip illustrating the endoflife explosion or nova that creates objects like the Helix Planetary Nebula (NGC 7293), and show how it would fill the space between our Sun and nearest star, Proxima Centauri.
