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."

    Read the article, bottom of the page: "Mira's tail is only visible in ultraviolet light, and does not show up in visible light."

    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.

    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.

    Whether you believe the writers thought this when they wrote it is another issue altogether.

    According to the script, they (Lucas) knew it and knew Solo was wrong. From http://www.blueharvest.net/scoops/anh-script.shtml (A New Hope script):

    HAN: Fast ship? You've never heard of the Millennium Falcon?

    BEN: Should I have?

    HAN: It's the ship that made the Kessel run in less than twelve
    parsecs!

    Ben reacts to Solo's stupid attempt to impress them with
    obvious misinformation.

    I started a list, but rather than underline my geek-dom of All Things Trek, I'll just demonstrate a mastery of Some Things Interweb:

    Kirk's Bedpost Notches

    In my defense, there were a couple that even I couldn't remember.
