Dan Witz | Do Not Enter

 The Brooklyn-based artist started the project in 2007, creating his own modifications – sometimes humorous, sometimes politically charged – of Do Not Enter signs and has since continued with the project in 2011 and 2012. The signs have been placed on the streets of Brooklyn, Vienna, Norway and Poland. The bald, white face that appears in many of the signs is Witz himself   via collabcubed.com

The Bubble Nebula
Blown by the wind from a massive star, this interstellar apparition has a surprisingly familiar shape. Cataloged as NGC 7635, it is also known simply as The Bubble Nebula. Although it looks delicate, the 10 light-year diameter bubble offers evidence of violent processes at work. Above and right of the Bubble’s center is a hot, O star, several hundred thousand times more luminous and around 45 times more massive than the Sun. A fierce stellar wind and intense radiation from that star has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud. The intriguing Bubble Nebula lies a mere 11,000 light-years away toward the boastful constellation Cassiopeia. This view of the cosmic bubble is composed of narrowband and broadband image data, capturing details in the emission region while recording a natural looking field of stars.
