Comet Shoemaker-Levy's First Fragment Impacts With Jupiter

 Comet Shoemaker-Levy's First Fragment Impacts With Jupiter

This NASA Hubble Space Telescope image of Jupiter's cloudtops was taken at 5:32 EDT on July 16, 1994, shortly after the impact of the first fragment (A) of comet Shoemaker-Levy 9. A violet (410 nanometer) filter of the Wide Field Planetary Camera 2 was used to make the image 1.5 hours after the impact.

The impact site is visible as a dark streak and crescent-shaped feature in the lower left of the image, and is several thousand kilometers across. The comet entered the atmosphere from the south in the direction of the streak at an angle of about 45 degrees from the vertical. The crescent-shaped feature may be the remains of the plume that was ejected back along the entry path of the projectile. The features are probably dark particles from the comet, or possibly condensates dredged up from Jupiter's deep atmosphere.

Comet Shoemaker-Levy 9 broke up during a close passage by Jupiter in July of 1992. The fragments will continue to impact the planet through 22 July 1994. Pre-encounter estimates of the energy of the combined impacts are highly uncertain, and range up to that of a million hydrogen bombs (a million megatons of TNT).

Jupiter was approximately 477 million miles (767 million kilometers) from Earth when the image was taken.

About The Object
Object Name Jupiter, Comet P/Shoemaker-Levy 9
About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
