I love these pale blue dot videos, Carl Sagan Is one of the people I most admire,
I first came across it way back from a YTMND clip and remember feeling very moved and inspired by Carl’s words, and the plinky plonky piano tune that sounds like a slowed down version of ‘running in the 90s’.
This is another good version with Pink Floyd’s ‘On the turning away’
And This is a video with just Carl talking.
And while I am spamming you with links here is another one, not Carl Sagan but a very interesting insight into our universe non the less, its about the Hubble deep field view.
