Black Hole Blasts Neighbor Galaxy with Deadly Jet 222

butterwise writes to mention that astronomers have, for the first time, witnessed a super-massive black hole hitting a nearby galaxy with a "death-star-like" beam of energy. The story also has a video with simulations, pictures, and explanations. "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."

      And considering that the major damage to any inhabited planets that may have been there would have been radiation effects, one has to wonder if there's any intelligent species over there digging up 1.4 billion year old, relatively undamaged artifacts on their planets surfaces right now ;)

    That would indirectly suggest that in this galaxy there was no sufficiently advanced life that would detect, and try to protect itself, or stop, said "death ray".

    Some people believe the universe is chock full of life, but this one is score for the skeptics. I remain a cautious optimist.

      If there's a civilization that can shut down supermassive black holes at will then we'd know about it by now. Either because we're on the menu or we're needed to help clean the sewer mains on the black-hole-shutting-down supership.

      Well, the Earth is pretty chock full of life, and if that thing aimed for us, we'd be amazingly screwed.

      Maybe its not even technologicaly and physically possible to protect yourself from something like that. At best, if there was a super high tech civilisation in that galaxy, they got their alien asses out of there. But even then, someone correct me if I'm wrong, but even if you have a ship capable of light speed, you better have had that technology LONG before the ray hit the galaxy to make it out in time.
      • if your ship was capable of doing the speed of light or even a significant portion of it then the radiation from the blackhole jet might be red-shifted enough that it would be easy to shield; instead of gamma radiation it might red-shift down to red light and not even have enough energy to power your solar cells decently.

      That would indirectly suggest that in this galaxy there was no sufficiently advanced life that would detect, and try to protect itself, or stop, said "death ray".

      Um, dude? That "death ray" has a significant scale relative to the size of a galaxy, all of it traveling at (x-rays, gamma rays) or close to (electrons) the speed of light. For one any species caught in its path wouldn't see it until it hit them, and two even if they knew about the beam it isn't clear that they could do anything about it except hide underground for thousands of years or bug out to another part of the galaxy, which itself would require faster-than-light travel. To actually redirect or shield themselves from the beam at a degree that would be visible in our telescopes would require technology on a scale that we can't even dream of.

      I find it highly odd that you would be skeptical of the existence of life arising elsewhere in the universe (which while we have no idea what exactly it takes, we know is possible because it has happened at least once), because of the apparent lack of faster than light travel (which according to our current theories is impossible) or even more miraculous feats of what amount to complete science fiction. We can't say that it could ever even be theoretically possible to be "sufficiently advanced" to pull off what you propose, much less if humanity could ever attain it.

      Have you seen the Hubble Deep Field [hubblesite.org]? That's an extremely narrow view of the sky, and it's completely stuffed with galaxies. And because this one particular galaxy has not, as far as we can tell, birthed a civilization with Q-like [wikipedia.org] powers, you're questioning whether there could be life anywhere else out there at all? That's literally the oddest form of skepticism I've ever heard.

      Unless this is just dead-pan humor. I'll admit that I have problems detecting it when done with subtlety.

        That deep field photo is humbling beyond words. It really gives you perspective on just how insignificant we are, in the philosophical grand scheme of things.

        To paraphrase Carl Sagan's Contact, if there isn't any intelligent life out there, it sure would be an awful big waste of space.

        I think what he meant was: There might be life in other galaxies, but this one's roasted for sure.
    • Maybe their solution was to get out of there (colonize other planets, flee into another dimension, etc) because they were able to formally prove there is no way to master a black hole?

      Alternatively, they may be taking advantage of this phenomenon, using the radiation somehow.

    We often take for granted when we see these cool renditions of distant space that these images are only possible when based on the leaps and bounds made with various telescopes over the last 50+ years:

    "Only now by combining the images of radio telescopes, the optical and ultraviolet eyes of Hubble Space Telescope and the Chandra X-ray Observatory, can researchers put together the entire violent story about this intergalactic mugging.

    The coordinated use of such an array of diverse and powerful telescopes is one of the unheralded triumphs of modern physics, Tyson said. "This is an example of the triumph of that exercise." http://dsc.discovery.com/news/2007/12/17/galaxy-black-hole-02.html [discovery.com]

    Just the fact that we can observe such a dramatic event is awe-inspiring.
    • Our eyes are so amazingly beyond any other organism's, that I say humans have abilities which are truly cosmic in scale. Think of the most powerful biological eye - probably a hawk or eagle's - and then compare the light-gathering and resolving power of it to the resolution and light gathered from an astronomical observation. It is a truly stellar distance, the separation.

      Yes, the biological human eye does not compare, but I consider our technology to be a part of us. After all, humans aren't really that we

        Agreed. Though, of course, each instrument has its special field of applicability.

        Human eyes are amazing, but really only have much acuity in the fovea centralis (thus microsaccades). Horses' eyes don't have the acuity we do in the center of their visual fields, but their relatively high-resolution field extends considerably father than ours. We don't have tapeta; many other animals have much better night-vision than we do. Many birds can see a ways into the ultraviolet regions; many insects and

      Unfortunate that at least some of that coordinated effort is slated to be decommissioned in the next little while... with both the Hubble and Arecibo (the latter not specifically named, but they did use the VLA radiotelescope) being punted, how much of this capability will we lose?

    The article states: Both galaxies are situated about 1.4 billion light-years away from Earth.

    and then goes on with: The offending galaxy probably began assaulting its companion about 1 million years ago...

    If the distance is 1.4 billion light years, light from the event should be taking that much time to reach us, and something that happened only a million years ago should not be visible yet.
