“A Catastrophe Happening in Front of Our Very Eyes”: The Environmental History of a Comet Crash on Jupiter
Earth is part of a vast cosmic environment, thus environmental history should embrace the whole universe. This article argues that changes in environments far removed from Earth have had profoundExpand
Disintegration of comet nuclei
The breaking up of comets into separate pieces, each with its own tail, was seen many times by astronomers of the past. The phenomenon was in sharp contrast to the idea of the eternal andExpand
Instrument Performance Enhancement and Modification through an Extended Instrument Paradigm
An extended instrument paradigm is proposed, developed and shown in various applications. The CBM (Chin, Blass, Mahan) method is an extension to the linear systems model of observing systems. In theExpand
Note on the structure of comet nuclei
Abstract The recent developments in cometary studies suggest rather low mean densities and weak structures for the nuclei. They appear to be accumulations of fairly discrete units loosely boundExpand
The Physics of Cometary Nuclei
The recent developments in cometary studies suggest rather low mean densities and weak structures for the nuclei. They appear to be accumulations of fairly discrete units loosely bound together, asExpand
Elastic properties of amorphous and crystalline ice films
Abstract Water is the basic ingredient of comets and interstellar dust. It is believed that the cometary ices were originally formed as amorphous ices that have since been reprocessed. In order toExpand
A Disabled Ship
Like a disabled ship heading helplessly for a barrier reef, Shoemaker-Levy 9 hurtled toward Jupiter. Crash week was approaching fast, and thanks to a stunning series of comet portraits sent down fromExpand
HST imaging of atmospheric phenomena created by the impact of comet Shoemaker-Levy 9
Hubble Space Telescope (HST) images reveal major atmospheric changes created by the collision of comet Shoemaker-Levy 9 with Jupiter and record the overall change in Jupiter's appearance as a result of the bombardment. Expand
Impact modellers not surprised


Density of comet Shoemaker–Levy 9 deduced by modelling breakup of the parent 'rubble pile'
FOR a week beginning 16 July 1994, fragments of comet Shoemaker-Levy 9 will collide with Jupiter each day. Although the fragments are probably smaller than originally estimated1, the impacts mayExpand
Origin of cometary nuclei as 'rubble piles'
COMETS are extremely fragile objects. Observations of outbursts and splitting have inspired suggestions that their nuclei are 'rubble piles', consisting of components that are weakly bonded, perhapsExpand
Estimate of the size of comet Shoemaker-Levy 9 from a tidal breakup model
THE spectacular 'string-of-pearls' appearance of periodic comet Shoemaker-Levy 9 (1993e) and its impending encounter with Jupiter's atmosphere have caused a flurry of speculation on the likelyExpand
On the density of Halley's comet
Abstract The density of Halley's comet is determined as a function of a parameterized time of visibility of ejected material, as a function of the angular deviation α from the Sun-comet direction ofExpand
Is the nucleus of comet Halley a low density body?
An important finding of the Vega and Giotto missions to comet Halley was evidence that the cometary nucleus is a consolidated body1–5. The shape, size and rotation of the nucleus were studied as wellExpand
Are cometary nuclei primordial rubble piles?
Whipple's1 icy conglomerate model for the cometary nucleus has had considerable success in explaining a variety of cometary phenomena such as gas production rates and nongravitational forces.Expand
