NASA Finds Star With a Tail

Andrew Stellman writes "NASA astronomers held a press conference announcing that a new ultraviolet mosaic from NASA's Galaxy Evolution Explorer shows a speeding star named Mira that's leaving an enormous trail of "seeds" for new solar systems. Mira is traveling faster than a speeding bullet, and has a tail that's 13 light-years long and over 30,000 years old. The website has images and a replay of the teleconference."

      I think it started with the urge to deny the existance of Kirk-Spock sexual tension...

      Roddenberry's intro to the novelization of Star Trek: The Motion Picture responds to the whole Kirk/Spock sexual tension thing in Kirk's voice with a disclaimer to the effect of (I'm paraphrasing from memory, and I read the book when it came out): "there's nothing wrong with two men being attracted to each other, but if I were to go in that direction, I think I'd choose a sexual partner who was interested more often than every 7 years." I can think of three women Kirk certainly slept with of the top of my head: the slave girl in Bread and Circuses, Miramanee, Carol Marcus; and there are a lot of probables.

  5. Faster than a speeding bullet? by SamP2 · · Score: 5, Insightful

    Newsflash: Our own Sun's velocity is 217 km/s (relative to the galactic center) and 20 km/s relative to the average speed of neighboring stars.

    For comparison, a "speeding bullet" slugs anywhere from around 1km/s (sniper rifle) to ~100m/s (short-barrel pistol).

    In addition, Wikipedia states that Mira's velocity is 63.8km/s -- which is actually slower than our own's sun (which has no "tail"), leading to two conclusions: (1) Mira's tail is caused by some other factor than it's velocity alone, and (2) Mira's speed is also so faster than a "speeding bullet" beyond comparison. In other words, the comparison is not just off-scale but also irrelevant.

    If you insist on using laymen's "cool-sounding" metaphors to describe scientific phenomena, at least check your facts and context, or you will just make a moron out of yourself.

      Yes, because when they say supersonic they couldn't possibly mean oh I don't know faster than the speed of sound...

      You know the speed that pressure changes can propogate through a fluid (such as the not-quite-vacuum intertelar medium around the star). That speed in which there's a change in the physics due to the formation of a shock wave (because the object is traveling faster than the pressure shift that "tells" the "upstream" fluid that the object is there).

      100km/s or there abouts - depends on the local density of the interstellar medium.

  11. Scientist as Educator by DynaSoar · · Score: 5, Funny

    I usually choke when journalists do a bad job presenting science. Sometimes the tables get turned, and they quote exactly what's said. Unfortunately. So, in the spirit of equal chain jerking:

    From TFA as presented on MSNBC: "If Neanderthal man had ultraviolet eyes and could look above the atmosphere, he could have seen the beginning of this tail forming," study leader Chris Martin, an astronomer at the California Institute of Technology, said during a teleconference Wednesday.

    AWEsome, d00d.

    And, if they had ultraviolet eyes on 30,000 light year long eye stalks, they could not only see
    above the atmosphere, they could see the tail as it formed, RIGHT WHERE IT WAS HAPPENING.

    OH. OH. And if the DINOSAURS had ultraviolet eyes, and could see above the atmosphere, they could see it 65 million years BEFORE it happened. And they could probably also see that asteroid coming and build SPACESHIPS, no wait, SPACE DINOSAUR MOTORCYCLES, they could get off the planet before it got hit, and fly to that star and live there, and then 65 million years later all wag their tails at the same time and make the star shoot off gas and dust like a BIG TAIL that we could see, because they wanted to say hi and let us know they were all OK and we shouldn't be all sad because we thought they all got extincted.

    I guess we can't all be Carl Sagan. Because then there would be BIL..... nevermind.
