Comet Shoemaker-Levy 9 splash on Jupiter

Comet Shoemaker-Levy 9/Jupiter collision. Colour image made by the Hubble Space Telescope (HST) of the large impact site of Fragment G of Comet Shoemaker-Levy 9. The impact occurred at 07.28 GMT on 18 July 1994. The impact site (or splash') is seen here as the complex dark circular feature just below centre. The impact site is a dark brown spot, around which are two crescent-shaped arcs. The lone dark spot immediately to the left of the G impact is the site of the earlier D event (11.42 GMT, 17 July)

Chemical weights

Assorted chemical weights. The different amount of each chemical represents a measurement known as the mole. One mole of any sample contains the same number of molecules or atoms. The weight (shown in grams) of each molar sample is determined by the weight of the molecules (the molecular weight) and is calculated from the weights of the atoms in the molecule. Three of the chemicals are hydrated with water (H2O). The chemical formulae are, clockwise from lower left: NaCl, FeCl3.6(H2O), CuSO4.5(H2O), KI, Co(NO3)2.6(H2O) and KMnO4. The heaviest atom here is iodine (I), 8 times heavier than oxygen (O). The transition metal compounds are coloured
