Palomar. Comet Shoemaker-Levy 9 was the ninth short-periodic comet discovered by Eugene and Carolyn Shoemaker and David Levy.
The fragments of Shoemaker-Levy 9 impacted Jupiter between July 16th and 22nd.
Astronomers using Hubble were surprised to see "sulfur-bearing compounds" such as hydrogen sulfide, as well as ammonia, as a result of the collision.A month after the collision, the sites were noticeably faded, and Hubble scientists declared that Jupiter's atmosphere would have no permanent change from the impacts.

Comet Shoemaker-Levy 9 is just one of the comets in our solar system, not quite as famous as Halley, but in 1993, Shoemaker-Levy 9 broke into pieces which scattered over Jupiter.
A 2014 follow-up report by NASA's Office of the Inspector General confirmed that.

It left a multiringed black cloud larger than Earth’s diameter.
"Impacts by comets or their dust streams are regular occurrences in planetary rings, altering them in ways that remain detectable decades later," the researchers Astronomers know today that impacts on Jupiter are fairly common.

Separated in time by an average of seven to eight hours, each fragment plunged deep into the Jovian atmosphere, exploding with tremendous energy and creating a bubble of super-hot gas called a “fireball.” As the fireball rose back out of the Jovian atmosphere, it deposited dark clouds of ejecta on top of the Jovian clouds.

Fragments of Comet Shoemaker-Levy 9 lined up along the comet's orbital path, in a composite of images taken by the Hubble Space Telescope in 1994. Its impact delivered energy equivalent to at least 48 billion tons of "Even with a ten-fold increase in the NEO Program budget in the past 5 years – from $4 million in fiscal year (FY) 2009 to $40 million in FY 2014 – NASA estimates that it has identified only about 10 percent of all asteroids 140 meters and larger," the OIG wrote in 2014.
