This Hubble picture, taken on July 23, is the sharpest visible-light picture taken of the impact feature. The observations were made with Hubble's new camera, the Wide Field Camera 3 (WFC3).
The combination of the Hubble data with mid-infrared images from ground-based telescopes will give astronomers an insight into changes of the vertical structure of Jupiter's atmosphere due to the impact. The expanding spot is twice the length of the United States.
First discovered by Australian amateur astronomer Anthony Wesley, the feature is the impact site and "backsplash" of material from a small object that plunged into Jupiter's atmosphere and disintegrated.
The only other time in history such a feature has been seen on Jupiter was in 1994 during the collision of fragments from comet Shoemaker-Levy 9. The spot looks strikingly similar to comet Shoemaker-Levy 9's impact features. The details seen in the Hubble view shows lumpiness in the debris plume caused by turbulence in Jupiter's atmosphere.
The impactor is estimated to be the size of several football fields. The force of the explosion on Jupiter was thousands of times more powerful than the suspected comet or asteroid that exploded in June 1908 over the Tunguska River Valley in Siberia.
This is a natural color image of Jupiter as seen in visible light.

| About The Object | |
|---|---|
| Object Name | Jupiter |
| Object Description | Planet |
| Distance | The semi-major axis of Jupiter's orbit about the sun is 5.2 astronomical units (483 million miles or 778 million km). On July 23, 2009 Jupiter was 381 million miles from Earth. |
| Dimensions | The planet has a diameter of roughly 88,789 miles (142,984 km) at the equator. |
| About The Data | |
| Data Description | The image was created from Hubble data from proposal : H. Hammel (Space Science Institute), A. Simon-Miller (NASA Goddard Space Flight Center), J. Clarke (Boston University), I. de Pater (University of California, Berkeley), K. Noll (STScI), G. Orton (Jet Propulsion Laboratory), A. Sanchez-Lavega (University of the Basque Country, Spain), and M. Wong (STScI). |
| Instrument | HST>WFC3/UVIS |
| Exposure Dates | July 23, 2009 19:00 UT |
| Filters | F225W (225 nm), F275W (275 nm), FQ378N (378 nm), FQ437N (437 nm), FQ508N (508nm), FQ634N (634 nm), FQ727N (727 nm), FQ889N (889 nm), FQ906N (906 nm), and FQ924N (924 nm) |
| About The Image | |
| Color Info | The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Three filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: FQ437N (437 nm) Green: FQ508N (508nm) Red: FQ634N (634 nm) |
