Strange New 'Twin' Worlds Found

toomanyairmiles writes "The BBC reports on the the discovery of 'twin worlds' which orbit each other, successfully blurring the line between planets and stars. 'Their existence challenges current theories about the formation of planets and stars.' according to the Journal of Science article which reports their existence. 'The pair belongs to what some astronomers believe is a new class of planet-like objects floating through space; so-called planetary mass objects, or "planemos", which are not bound to stars.'"

      Well, considering the definition of planemo as anything with planetary mass not orbiting a star... A sufficiently large space station / space ship would qualify as a planemo. So, unfortunately, that joke doesn't really apply here. It is, however, still "no moon." :)

      I like Planemo and Planelarry, implying, of course, the future discovery of Planecurly and a receding Planeshemp.

    Once again proving that astronomers should not be naming things while drunk. Here's a handy reminder: "Remember the Planemos!"

    It also shows that no scientific theory can be trusted to be valid past lunch, we just never know when we'll find something new that blows the standing knowledge out of the water.

    Can it all really be random?

    In terms of such stars as Ben Affleck, the similarities do start to build up.

    You've got questions...I've got answers

    why do we have a planet that doesn't follow the plane?
    It marches to the beat of a different drummer. Its the "alternative" planet.

    is it slowly falling into line with the rest?
    Yes, they always do.

    Was Pluto originally extra-solar?
    We were all "extra-solar" at one point or another...know what I mean.

    Could it have developed in this eccentric orbit if it were originally part of the solar system when it formed?
    If it were originally a part of the "system" then it wouldn't seem so eccentic now would it?

    Is it possible that Pluto somehow, amongst the billions of years our system has been around, floated into orbit here for good, from Out There?
    Yeah, it got bored and had nothing better to do the next few billion years or so.

    And if so, if there are enough of these free-floating masses out there, what kind of percentage of the unobservable 'dark matter' might this account for?
    Obviouslly, 42

    Thank you, thank you. I'll be here all day.

  12. Hey I saw this movie! by XJHardware · · Score: 2, Funny

    The first planemo will make a very close approach to Earth. The second will smack right into earth. But by then the spaceships we cobble together with nifty 50's retro-tech will have blasted off with the lucky few colonists to build a new civilization. Too bad with such a small gene pool they'll devolve into slack jawed mouth breathers in a few generations. Looks like the future of reality TV is assured.
