I have a fondness for the way NASA and the Hubble scientists depict the galaxies and nebulae captured in images over the years. Yes, the photos have been filtered various ways and look like paintings, but they're not. They're real live outer space objects that look like art.
And a Rose Galaxy for Valentine's Day (yes, you've seen it here before):
It seems no matter how far out we cast our eyes, or no matter how microscopically we peer in, we find beauty and complexity.
