    I am sure that you guys heard about the mystery collision on Jupiter last Sunday and it seems to be that a comet or meteoroid hit Jupiter, but the question is how do we know? why we didn't know that the collision is going to happen? What if this thing came to Earth?

    Spot on Jupiter About the Size of Earth
    Jupiter had a "deep space collision." Either a meteor or meteoroid or comet hit Jupiter. Apparently the offender was about the size of earth.

    Ned Potter of ABC News Technology & Science has written an article titled "Deep Impact: Jupiter Hit by Comet or Meteoroid."

    Whatever hit Jupiter was "swallowed up" by the planet's massive atmosphere of ammonia and methane.

    The impact left a scar that may be visible up to a week.

    The event was first observed by amateur Australian astronomer Anthony Wesley. However it was verified by NASA's infrared Telescope Facility on Mauna Kea in Hawaii.

    There is a chance that scientists will never know what slammed into Jupiter because of its environment.

    Boy... that would destroy our planet, not life, the actual planet would be destroyed.

    People think we/scientists know when things are coming at us, we don't. this thing was huge and we never noticed it.

    umm what they were saying on the radio was that the SCAR was the size of earth, not the now former commet, that was only 1 mile across (aparently) but would have destroyed england compleatly (what a pity

    I heard it was the size of the pacific, to bad we don't have any probes in orbit a close up would have been dam spectaculair

    That the scar is roughly the size of Earth doesn't mean the meteorite/comet was. In fact, it means that it was smaller..

    I'd be headed for the nearest cave if Jupiter were really hit by an Earth-sized object. There would be alot of ejecta from such a collision.
    It would be interesting to see how much the orbits of Jupiter's moons would change as such an object would be massive enough to alter the gravitational balance of Jupiter's system.

    You think? Jupiter is made almost entirely of gasses, and have a very, very high escape velocity. I wouldn't be surprised if an earth-sized object was simply swallowed up with little or no ejecta.

    I stand corrected...I knew Jupiter's escape velocity was high but didn't realize it is over 4X the Earth's! (59km/s vs. 11km/s) However, the composition of Jupiter wouldn't make much difference, as the compression and rebound of atmospheric gases would be much the same as solid matter at these high temp's and pressures.

    LOOK! UP in the sky! It's a meteor. It's a comet. It's an asteroid!

    I don't think anyone was experiencing or observing impacts billions of years ago, unless you're counting bacteria.

    Does anybody think that a large comet ocean impact with the Earth could be the cause of a past ice age?? (The spray would block out the sun (blanket cloud cover) --> cooling planet --> ice caps expand --> sunlight reflected back by the ice --> cooling planet --> tips planet into ice age)

    Well on VENUS TOO!!

    Venus got hit apparently the same day as Jupiter at around the same latitude.
    Nasa isn't confirming it is an asteroid, but it is normal that they do not confirm something that could span a panic! Because WE are stuck between the TWO and both got struck by huge "bricks" at the same day!
    Talk about an inconvenient occurrence!

    Since I cannot yet post links (not 20 posts yet), you will have to search for Venus bright spot .... Because they won't say it is a crash :bugeye:

    Well they wouldn't say it's a "crash" since it wasn't.
    "Impact" would be used but never "crash".

    look at the actual positions of the planets in their orbits. we aren't actuall anywhere near jupiter or venus. also, if they were both hit, they weren't hit by the same thing, because again, they aren't actually anywhere near each other.
