Thermal infrared measurements showed the impact site was warm and spectroscopic analysis detected the production of excess hot ammonia and silica-rich dust in the upper regions of Jupiter's atmosphere. The waves were thought to be travelling within a stable layer acting as a About an hour after fragment K entered Jupiter, observers recorded Some astronomers had suggested that the impacts might have a noticeable effect on the Voyager 2 failed to detect anything with calculations showing that the fireballs were just below the craft's limit of detection.One of the surprises of the impacts was the small amount of water revealed compared to prior predictions.Astronomers did not observe large amounts of water following the collisions, and later impact studies found that fragmentation and destruction of the cometary fragments in an 'airburst' probably occurred at much higher altitudes than previously expected, with even the largest fragments being destroyed when the pressure reached 250 kPa (36 psi), well above the expected depth of the water layer.
However as it rotated further into view, and the conditions improved I suddenly realised that it wasn't just dark, it was The spot's prominence indicated that it was composed of high-altitude aerosols similar to those seen during the SL9 impact.The force of the explosion on Jupiter was thousands of times more powerful than the suspected comet or asteroid that The object that hit Jupiter was not identified before Wesley discovered the impact. subscription. you are agreeing to our Infrared Telescope Facility/Handout/JPL/NASA/ReutersFewer jobs at City Hall - one way Flynn can begin to arrest the deficit The bad news: The calculations also indicated that the asteroid or comet fragment was much smaller than previously estimated. Scientists have concluded that another impact event had occurred, but this time a more compact and strong object, probably a small undiscovered asteroid, was the cause.The impact of SL9 highlighted Jupiter's role as a "cosmic vacuum cleaner" for the inner Solar System (In 2009, it was shown that the presence of a smaller planet at Jupiter's position in the Solar System might increase the impact rate of comets on the Earth significantly. You can renew your subscription or Asteroids, Stephen Hawking believes, that one of the major factors in the possible scarcity of intelligent life in our galaxy is the high probability of an asteroid or comet colliding with inhabited planets. "Shoemaker–Levy" redirects here. Scientists study satellite 'tractors' and nuclear weapons as ways to divert asteroids headed our way.For all its scientific interest, however, the collision also serves as a stark reminder that the solar system remains a shooting gallery – with Earth, as well as Jupiter, on the wrong side of the firing line.The object's signature on Jupiter's cloud tops initially was discovered by Australian amateur astronomer When it comes to objects Earthlings should keep an eye on, the catalog scientists have amassed is swelling.Since 1995, astronomers associated with 10 search projects have discovered more than 6,200 near-Earth asteroids of all sizes, according to data from JPL. "We believe it was a comet or asteroid measuring perhaps a few hundred meters wide," says Don Yeomans of NASA's Near-Earth Object Office at JPL. This and other recent models call into question the nature of Jupiter's influence on Earth impacts.

Where do asteroids go to die? The smaller fragments were probably destroyed before they even reached the cloud layer.The visible scars from the impacts could be seen on Jupiter for many months.
"No one saw the object prior to impact.
