From the article:
"Amateur astronomer Anthony Wesley from Canberra, Australia captured an image of Jupiter on July 19 showing a possible new impact site. Anthony's image shows a new dark spot in the South Polar Region of Jupiter, at approximately 216° longitude in System 2. It looks very similar to the impact marks made on Jupiter when comet Shoemaker-Levy 9 crashed into the gas giant in 1994. (But read the Bad Astronomer's post that the black spot could also be weather.)"

    Yes, but what I am trying to say is that the "Universe Today" seems to have flipped the image and the southern hemisphere, now, has become northern, (look at the Universe's Today image again and compare with that from NASA.
    What confused me is that articles say it's in the South, but the photo in the "Universe Today" shows it in the North, ( www.universetoday.com/2009/07...jupiter/ ); (unless I am REALLY not seeing something there.)

    Below is the release from JPL/NASA:

    "New NASA Images Indicate Object Hits Jupiter"

    Scientists have found evidence that another object has bombarded Jupiter, exactly 15 years after the first impacts by the comet Shoemaker-Levy 9.

    Following up on a tip by an amateur astronomer that a new dark “scar” had suddenly appeared on Jupiter, this morning between 3 and 9 a.m. PDT (6 a.m. and noon EDT) scientists at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., using NASA’s Infrared Telescope Facility at the summit of Mauna Kea, Hawaii, gathered evidence indicating an impact.

    New infrared images show the likely impact point was near the south polar region, with a visibly dark "scar" and bright upwelling particles in the upper atmosphere detected in near-infrared wavelengths, and a warming of the upper troposphere with possible extra emission from ammonia gas detected at mid-infrared wavelengths.

    “We were extremely lucky to be seeing Jupiter at exactly the right time, the right hour, the right side of Jupiter to witness the event. We couldn’t have planned it better,” said Glenn Orton, a scientist at JPL.

    The new Jupiter images are online at: www.jpl.nasa.gov/news/news.cfm .

    Orton and his team of astronomers kicked into gear early in the morning and haven’t stopped tracking the planet. They are downloading data now and are working to get additional observing time on this and other telescopes.

    This image was taken at 1.65 microns, a wavelength sensitive to sunlight reflected from high in Jupiter’s atmosphere, and it shows both the bright center of the scar (bottom left) and the debris to its northwest (upper left).

    “It could be the impact of a comet, but we don’t know for sure yet,” said Orton. “It’s been a whirlwind of a day, and this on the anniversary of the Shoemaker-Levy 9 and Apollo anniversaries is amazing.”

    Shoemaker-Levy 9 was a comet that had been seen to break into many pieces before the pieces hit Jupiter in 1994.

    Leigh Fletcher, a NASA postdoctoral student at JPL who worked with Orton during these latest observations said, “Given the rarity of these events, it’s extremely exciting to be involved in these observations. These are the most exciting observations I’ve seen in my five years of observing the outer planets!”

    The observations were made possible in large measure by the extraordinary efforts of the Infrared Telescope Facility staff, including telescope operator William Golisch, who adroitly moved three instruments in and out of the field during the short time the scar was visible on the planet, providing the wide wavelength coverage.
