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.

The Swan Glowing in Flight Best known as a swan winging its way across the night, the constellation Cygnus is easily seen in the northern hemisphere’s summertime sky. This new view of the Cygnus-X star-forming region by the Herschel Telescope highlights chaotic networks of dust and gas that point to sites of massive star formation. This image combines far-infrared data acquired at 70 micron (corresponding to the blue channel); 160 micron (corresponding to the green channel); and 250 micron (corresponding to the red channel). The observations were made on May 24, 2010, and Dec. 18, 2010.

Sol 2951 After spending 19 weeks working in one place while solar power was too low for driving during the Martian winter, NASA’s Mars Exploration Rover Opportunity is on the move again. The winter worksite was on the north slope of an outcrop called Greeley Haven. The rover used its rear hazard-avoidance camera after nearly completing the May 8 drive, capturing this view looking back at the Greeley Haven. Since landing in the Meridiani region of Mars on Jan. 25, 2004, Universal Time and EST (Jan. 24, PST), Opportunity has driven 21.4 miles (34.4 kilometers). This image is of Opportunity’s traverse map from Sol 2951 and shows the entirety of the rover’s travels to this point.

ghostlyknight: Oh, you sly dog.

People are saying Mass Effect 1 and/or the Mako is a pain in the ass

sissysouthpaw:

NO YOU ARE A PAIN IN THE ASS

That’s just where my brain goes, it can’t be helped. :D
