Screaming monkey nebula
OK, I made that name up. It's actually called DR 6, which isn't nearly as much fun, especially at this time of year.

This is an infrared Spitzer Space Telescope image of the gas cloud, which is forming a dozen or so stars inside it. The eyes and mouth are bubbles in the gas blown by the winds of the newborn stars. 

So in a way, it really is yelling. But at a distance of 4000 light years - and across the vacuum of space -  there's nothing we can hear. 

Except: BOO!
