From NASA:

A powerful jet from a super massive black hole is blasting a nearby galaxy, according to new findings from NASA observatories. This never-before witnessed galactic violence may have a profound effect on planets in the jet’s path and trigger a burst of star formation in its destructive wake.

Known as 3C321, the system contains two galaxies in orbit around each other. Data from NASA’s Chandra X-ray Observatory show both galaxies contain super massive black holes at their centers, but the larger galaxy has a jet emanating from the vicinity of its black hole. The smaller galaxy apparently has swung into the path of this jet.

The effect of the jet on the companion galaxy is likely to be substantial, because the galaxies in 3C321 are extremely close at a distance of only about 20,000 light years apart. They lie approximately the same distance as Earth is from the center of the Milky Way galaxy.

Another unique aspect of the discovery in 3C321 is how relatively short-lived this event is on a cosmic time scale. Features seen in the Very Large Array and Chandra images indicate that the jet began impacting the galaxy about one million years ago, a small fraction of the system’s lifetime. This means such an alignment is quite rare in the nearby universe, making 3C321 an important opportunity to study such a phenomenon.


Just when you think that our challenges are daunting, along comes the universe with a million-year-old show to put us in our place.

    hmmmm, ya think?

    Although I can almost hear 3C321-Bush..”…all the data isn’t in yet.  Scientists still disag…………………………………………………………………

  2. and reflecting on what it is a picture of, the immensity of it, leaves me feeling, well, reverent.

    Thanks NSP 🙂

  3. “The Search for Signs of Intelligent Life in the Universe” by Jane Wagner and performed by Lily Tomlin. Trudy is taking her “space chums” to a play because they want to learn what its like to have goose bumps:

    On the way to the play, we stopped to look at the stars.

    And as usual,

    I felt in awe.

    And then I felt ever deeper in awe at this capacity we have to be

    in awe about something.

    Then I became even more awestruck

    at the thought that I was,

    in some small way,

    a part of that

    which I was in awe about.

    And this feeling went on

    and on

    and on…

    My space chums got a word for it:

    “awe infinitum.”

    Becuase at the point you can comprehend how

    incomprehensible it all is

    You’re about as smart as you need to be.

    Suddenly I burst into song:


    sweet mystery of life,

    at last I’ve found thee.”

    And I felt so good inside

    and my heart felt so full,

    I decided I would set time aside each day to do awe-robics.
