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.

At the close of their commercial career, these gorgeous beasts served as backup A/C for the Lockheed Electra in the Boston to Newark Easter Shuttle. Night engine starts were the best with the exhausts expelling flames.
Some folks out at OKC have a TWA Super Connie pretty much restored. http://www.airlinehistorymuseum.com/
wonderful a/c– fond memories of riding airlines during the 50′s–
looked forward to airline flights then–far cry from using them now—
i haven’t been on the airlines in almost a year now-=i will not use them unless it’s a “must use” case–i have a new rule–if i can drive it in 14 hours i will drive
Marvellous nostalgia
