4.5/5

Audiobook narrated by Carl Sagan and Ann Druyan.

Following on from Cosmos, I decided to listen to Pale Blue Dot and it was amazing. Whereas Cosmos was more focused on the nature of the universe, Pale Blue Dot explores humanities relationship with the universe and how we have and maybe will in the future venture forth from Terra Firma.

- I very much enjoyed the balance between known science and speculation in this book. Originally published in 1994, certain things have come to pass since then but Sagan acknowledges the known limitations at time of writing. Still, the book is conservatively hopeful and I really liked that.

- As a sci-fi fan, the discussions around human colonisation of other planets and other space entities was fascinating. Terraforming, travel, communication: lots of ideas are covered with accompanying scientific principles that inspired my mind to dream of new worlds. 

- The audiobook version I listened to was made up of a mix of the original tape recordings by Sagan and the missing portions reread by Druyan. To hear the wobble of analogue tape in Sagan's portions made my weird 90s kid brain happy. Despite the mix, the audio was well put together.

A wonderful follow up to Cosmos. I would recommend it to anyone with an interest in human exploration and potential colonisation of space.
