Ever wonder what “they” meant when talking about a painted sky?

Wonder no more:

PERSIAN GULF (Dec. 22, 2008) The guided-missile destroyer USS Ramage (DDG 61) transits through the Persian Gulf. Ramage is deployed as part of the Iwo Jima Expeditionary Strike Group (ESG) supporting maritime security operations in the U.S. 5th Fleet area of operations. MSO help develop security in the maritime environment. From security arises stability that results in global economic prosperity. (U.S. Navy photo by Chief Fire Controlman Michael Clemente/Released)

So did I, Byron. I commissioned RAMAGE back in 1995 and a fine warship she is. Fair Winds, Red Thunder.

Wow. I had no idea this photo was going to go so viral when I took it. This was one of a whole series I snapped. If anyone wants any others, just email me.

Active Black Hole Squashes Star Formation

New data from the Herschel Space Observatory shows that galaxies with the most powerful, active, supermassive black holes at their cores produce fewer stars than galaxies with less ones. Supermassive black holes are believed to reside in the hearts of all large galaxies. When gas falls upon these monsters, the materials are accelerated and heated around the black hole, releasing great torrents of energy. In the process, active black holes often generate colossal jets that blast out twin streams of heated matter. Inflows of gas into a galaxy also fuel the formation of new stars. In a new study of distant galaxies, Herschel helped show that star formation and black hole activity increase together, but only up to a point. Astronomers think that if an active black hole flares up too much, it starts spewing radiation that prevents raw material from coalescing into new stars. This artist concept of the local galaxy Arp 220, captured by the Hubble Space Telescope, helps illustrate the Herschel results. The bright core of the galaxy, paired with an overlaid artist's impression of jets emanating from it, indicate that the central black hole's activity is intensifying. As the active black hole continues to rev up, the rate of star formation will, in turn, be suppressed in the galaxy. Astronomers want to further study how star formation and black hole activity are intertwined. Herschel is a European Space Agency cornerstone mission, with science instruments provided by consortia of European institutes, with important participation by NASA. Image Credit: NASA/JPL-Caltech
