comet jupiter collision 2009
subscription. We 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. you are agreeing to our "On July 23rd, the Hubble Space Telescope took its first pictures of the blast site. Intense studies of the comet were undertaken, and as its orbit became more accurately established, the possibility of a collision became a certainty. 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.
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. 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.

On the night of July 19, 2009, Wesley noticed a dark spot on Jupiter that hadn't been there before.

Space Telescope Science Institute director Matt Mountain allocated emergency telescope time to a team of astronomers led by Heidi Hammel of the Space Science Institute in Boulder, Colorado.As usual, Hubble photos stole the show.
