The National Aeronautics and Space Administration (NASA) Infrared Telescope Facility was used to investigate the collision of comet Shoemaker-Levy 9 with Jupiter from 12 July to 7 August 1994. Strong thermal infrared emission lasting several minutes was observed after the impacts of fragments C, G, and R. All impacts warmed the stratosphere and some the troposphere up to several degrees. The abundance of stratospheric ammonia increased by more than 50 times. Impact-related particles extended up to a level where the atmospheric pressure measured several millibars. The north polar near-infrared aurora brightened by nearly a factor of 5 a week after the impacts.
美国国家航空航天局（NASA）的红外望远镜设施于1994年7月12日至8月7日用于研究苏梅克-列维9号彗星与木星的碰撞。在碎片C、G和R撞击后，观测到持续数分钟的强烈热红外辐射。所有撞击都使平流层升温，部分撞击使对流层升温达数度。平流层氨的丰度增加了50多倍。与撞击相关的粒子延伸至大气压力为几毫巴的高度。撞击一周后，北极近红外极光亮度增强了近5倍。
