blasting news from sky 2007.dec.17.:
A powerful jet from a supermassive black hole is blasting a nearby galaxy in the system known as 3C321, according to new results from NASA. This galactic violence, never seen before, could have a profound effect on any planets in the path of the jet and trigger a burst of star formation in the wake of its destruction.

For the first time astronomers have witnessed a supermassive black hole blasting its galactic neighbor with a deadly beam of energy.
The "death star galaxy," as NASA astronomers called it, could obliterate the atmospheres of planets but also trigger the birth of stars in the wake of its destructive beam. Fortunately, the cosmic violence is a safe distance from our own neck of the cosmos.
"We've seen many jets produced by black holes, but this is the first time we've seen one punch into another galaxy like we're seeing here," said Dan Evans, astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. "This jet could be causing all sorts of problems for the smaller galaxy it is pummeling."
Evans and his colleagues detail their findings in an upcoming issue of the Astrophysical Journal.

seeing this and some other threads i have already wandered
if a "Current Astronomical Events" forum on Sky forums would be reasonable.

Hi syzygy!
A forum about "Current Astronomical Events" sounds like a great idea, there are so many amazing discoveries and research results published on so many different websites that it is difficult to keep up-to-date even on a minimum level.
I only wish I had more time to come here on a regular basis.
Happy holidays!
Cheers, H

One of the amazing things about astronomy post-WW2 was that as new wavelengths other than optical (visible light) were used, totally different objects were seen:
Radio (starting in late 1940's) -- active galactic nuclei and SNR (Supernova Remnants);
X-Ray (starting in mid 1960's) -- black holes, clusters of galaxies, SNR;
Infra-red (starting in 1960's?) -- infant stars, protoplanetary disks;
Gamma-ray (starting in 1980's?) -- neutron stars??? other???
Does Google have any plans to include other, non-optical sky surveys and images into the GS framework? It would be great to be able to click layers and add the radio and X-ray of this image over the (default) optical layer.
