Supermassive black hole blasts neighbor with beam of energy

For the first time ever NASA astronomers spotted a supermassive black hole that blasts 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."

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. Both galaxies are situated 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."
