My first car was a 1971 Pontiac Grand Prix with the 400 c.i. V-8 and a Rochester 4-barrel carb. Developed under the guidance of good ol’ John Z. Delorean, long before the days of the DMC, Irish labor strikes, and cocaine busts. Two tons of total mobility and the longest hood in the business, was I think the way he put it about the Grand Prix. You could fit 12 people and half a dozen cases of beer in it and head for the beach. At 100 it would start to float on its wheels as the air got under the chassis and it would get a little sporty driving it. On the other hand, you could SEE the fuel gauge fall as you motored around.
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.

Hi, steeljawscribe.com – da best. Keep it going!
Pett
you are so talented that you posted this blog.good job..
This really saddens me. I never owned a Pontiac (being a Chevy kinda guy), but I’m danged glad they were there.
