Ultraviolet spectra obtained with the Hubble Space Telescope identified at least 10 molecules and atoms in the perturbed stratosphere near the G impact site, most never before observed in Jupiter. The large mass of sulfur-containing material, more than 10(14) grams in S2 alone, indicates that many of the sulfur-containing molecules S2, CS2, CS, H2S, and S+ may be derived from a sulfur-bearing parent molecule native to Jupiter. If so, the fragment must have penetrated at least as deep as the predicted NH4SH cloud at a pressure of approximately 1 to 2 bars. Stratospheric NH3 was also observed, which is consistent with fragment penetration below the cloud tops. Approximately 10(7) grams of neutral and ionized metals were observed in emission, including Mg II, Mg I, Si I, Fe I, and Fe II. Oxygen-containing molecules were conspicuous by their absence; upper limits for SO2, SO, CO, SiO, and H2O are derived.
通过哈勃太空望远镜获得的紫外线光谱在撞击点附近受扰动的平流层中识别出至少10种分子和原子，其中大多数是在木星上从未观测到的。大量含硫物质，仅S2就超过10¹⁴克，这表明许多含硫分子S2、CS2、CS、H2S和S⁺可能源自木星原生的含硫母体分子。如果是这样，碎片必定至少穿透到了预测的NH4SH云所在深度，压力约为1至2巴。平流层中也观测到了NH3，这与碎片穿透到云层顶部以下的情况相符。观测到约10⁷克中性和离子化金属发出的光，包括Mg II、Mg I、Si I、Fe I和Fe II。含氧化合物分子明显未被观测到；得出了SO2、SO、CO、SiO和H2O的上限。
