Jud Turner's latest sculpture is the haunting "Blind Eye Sees All (No Secrets Anymore)" (above); he's produced 50 miniatures (right) based on it whose sale benefits the Electronic Frontier Foundation. He writes, "I am saddened at what my country has become in the last 30 years. I read '1984' in 1984 as a 14 year old, and have worried about the rise of the surveillance state ever since.

NGC 1097 is a Seyfert galaxy. Lurking at the very center of the galaxy, a supermassive black hole 100 million times the mass of our sun is gradually sucking in the matter around it. The area immediately around the black hole shines powerfully with radiation coming from the material falling in." Read the rest
