Photos: Jupiter Struck By Space Rock (Again)

One Hit (to the Body)

A variety of images depict the spot on Jupiter likely caused by an asteroid, though a comet was initially suspected, in July 2009. It appeared similar to the impacts of Comet Shoemaker-Levy's fragments on Jupiter in 1994. This image shows the impact site as a yellow spot at center bottom, and was taken by the Gemini North telecope on Mauna Kea, Hawaii, July 22, 2009.

Images Are Worth Repeating

Look Sharp!

Hubble Space Telescope took the sharpest visible-light picture of the atmospheric debris from the collision with an asteroid on July 19, 2009. Notably, this was Hubble's first science observation following its repair and upgrade.

The scar from the impact appeared July 19 in Jupiter's southern hemisphere, and grew larger than the Pacific Ocean. This infrared image taken with Keck II on July 20 shows the new feature observed on Jupiter and its relative size compared to Earth.

Wrong Way Up

Hubble used its Wide Field Camera 3 (WFC3) to take this picture on July 23, 2009, including the newly discovered spot.

Feels Like the First Time

Hubble used its brand-new camera, the Wide Field Camera 3 (WFC3), to take its first full-disk natural-color image of Jupiter. It is the sharpest visible-light picture of Jupiter since the New Horizons' flyby in 2007. The dark smudge at bottom right represents debris from a comet or asteroid that plunged into Jupiter's atmosphere and disintegrated.

Train Drops on Jupiter

Six images made by Hubble combine in this mosaic of Comet P/Shoemaker-Levy 9, taken on May 17, 1994, before the fragments collided with Jupiter. At that time, the comet's train of 21 fragments stretched 710 thousand miles (1.1 million km), or 3 times the distance between Earth and the Moon.
