I've seen this on pinterest a couple times but it's one of those crazy link chains where one image links back to a tumblr, which links to another tumblr, which links to weheartit and nowhere can you find the original source. So if anyone knows who made this please let me know! I'd like to credit them & probably buy a print :)
Anyway, I think the quote is absolutely beautiful. I love nighttime -- I like the still quiet, the feeling of being awake when almost everyone else in your time zone is fast asleep and obviously being able to see the stars. Night is the only time that the naked eye can peek out into the universe, and I think that's lovely.
I will admit, despite the fact that I am a night owl, I do get scared of the dark sometimes. Although, strangely, I'm never scared of the dark when I'm outside, only when I'm inside. It's stupid because it's a lot more likely that a killer would be lurking in my backyard than under my bed, but I suppose fear isn't usually caused by rational thinking...
Update: The quote isn't actually by Galileo, but by poet Sarah Williams. You can read her poem and see my own artwork with the quote in this star stuff post :)
