From the great book "Our Universe" by National Geographic. Note the caption under the theoretical life on Pluto illustration.

I have that book (somewhere)! Loved it when I was a kid. I had three similar “coffee-table” astronomy books, all pre-Hubble, and looking at them now they seem so drab and uninformative (not to mention all the obsolete facts due to Science Marches On).

Whoa, I scanned the thread and saw that picture and it brought back many memories of paging through it when I was a child.

Wow! I had that book when I was a kid. I haven’t thought about it in years but I remember reading it endlessly.

Amazing book. I pored over it extensively when I was a kid.
