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 its 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.
Cosmic death
The deadly galaxy the largest of two in a system known as 3C321 is aiming the high-energy jet from its center at a smaller galaxy 20,000 light-years away from it, or roughly the distance from Earth to the Milky Way's core. The entire system is located about 1.4 billion light-years away from Earth.
A bright spot in a NASA composite image reveals that the beam is striking the edge of the smaller galaxy, deflecting the spindle of energy into intergalactic space. While not a direct hit, astronomers said the consequences are frightening.
"This is a fascinating result, and we can be glad that we're seeing it from a safe distance," said Neil deGrasse Tyson, an astrophysicist at the American Museum of Natural History in New York who did not contribute to the study. "Knowing how lethal the radiation from the jet could be, I wouldn't want to be anywhere near its line of fire."

This composite image shows the jet from a black hole at the center of a galaxy, at left, striking the edge of another galaxy. The image combines X-ray emissions seen by the Chandra X-Ray Observatory (purple), optical and ultraviolet data from the Hubble Space Telescope (red and orange) and radio emissions from the Very Large Array and the MERLIN array (blue).

Marvin is ticked.
OMG! Remember the guy in the next cube I told you about??? I think this is about him!
Galaxy fight!!!
But AM this is news...death rays from outer space.....don’t happen everyday.
OMG....I told you.
Looks like some shouldn't have ordered the chili.
Its not beautiful in that neighborhood.
Something must be happening. I’ve got another guy posting materials engineering stuff under “Philosophy.”

"you shall see signs in the sky...."
I told you...Marvin is not happy.
ahh, yes. the devil's in the details.
ROFL!
Was it hijacked? Any sounds like "Allah akbar" being picked up?
Aiiiiiiiiiieeeee!
