A Hyper-Velocity Impact In the Asteroid Belt?

Posted by Soulskill on from the i-played-that-game dept.

astroengine writes "Astronomers have spotted something rather odd in the asteroid belt. It looks like a comet, but it's got a circular orbit, similar to an asteroid. Whether it's an asteroid or a comet, it has a long, comet-like tail, suggesting something is being vented into space. Some experts think it could be a very rare comet/asteroid hybrid being heated by the sun, but there's an even more exciting possibility: It could be the first ever observation of two asteroids colliding in the asteroid belt."

    A collision between asteroids? Who wants to bet a woman was driving one of them?

      My girlfriend and wife both agree that woman are terrible drivers, hence I do all the driving on any trip.

      That's funny, the last time I was with your wife and girlfriend they did all the driving, if ya know what I mean...... ;)

  2. Why there's a difference. by argent · · Score: 5, Informative

    There's a reason you don't normally see icy bodies in circular orbits in the asteroid belt: they'd be blown clean of the ice within a fairly short period of time, astronomically speaking. that's what the tail consists of, dust embedded in the ice being released as the ice sublimes. Which means that the ice here has to have been exposed fairly recently.

    Seriously...not anything big but something Tunguska sized would do, especially over a moderately populated area.

    We spend peanuts on detecting potential collisions that could be the cause of the next extinction event. Mark my words, there'll be more money spent on earthquake analysis for Haiti and other "sensational" causes than will be spent on detecting PHOs (potentially hazardous objects) in the next 10 years. I am not denigrating the need to spend money on Haiti - that's a tragedy for sure - but when you look at how reactive we are with public money (New Orleans, anyone? Despite warnings, no one saw this coming?) when a much smaller amount spent up-front would potentially save not just a lot more lives but a lot more money....if better building codes had been in force in Haiti - how many more people would have survived? How much money would have been saved?

    I despair for our race. If we saw a dinosaur killer coming and had a program in place already we could probably survive it. Asteroids move slowly but are heavy and require a lot of time/energy to deflect so we would see them early and be able to react...comets move much, much faster but are lighter so presumably if we had the detection gear and a few mass drivers in space already, we could deal with it in a safe time frame.

    So give us our Haiti or Katrina from space, please. Make it hurt but not too much - just enough to wake up the people handing out government cash.

  4. Probably not by Angst+Badger · · Score: 5, Funny

    Everyone knows the asteroids pass right through each other. It's either been shot or it has collided with a ship.

    Honestly, what kind of education are scientists getting these days?
