TLDR
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.Abstract:
Hubble Space Telescope (HST) images reveal major atmospheric changes created by the collision of comet Shoemaker-Levy 9 with Jupiter. Plumes rose to 3000 kilometers with ejection velocities on the order of 10 kilometers second-1; some plumes were visible in the shadow of Jupiter before rising into sunlight. During some impacts, the incoming bolide may have been detected. Impact times were on average about 8 minutes later than predicted. Atmospheric waves were seen with a wave front speed of 454 +/- 20 meters second-1. The HST images reveal impact site evolution and record the overall change in Jupiter's appearance as a result of the bombardment.read more

Environmental Perturbations Caused by the Impacts of Asteroids and Comets
TL;DR: In this paper, the authors review the major impact-associated mechanisms proposed to cause extinction at the Cretaceous-Tertiary geological boundary and discuss how the proposed extinction mechanisms may relate to the environmental consequences of asteroid and comet impacts in general.

Hydrocode simulation of the Chicxulub impact event and the production of climatically active gases
TL;DR: In this article, the authors constructed a numerical model of the Chicxulub impact event using the Chart-D Squared (CSQ) code coupled with the ANalytic Equation Of State (ANEOS) package.

Computation of seismograms and atmospheric oscillations by normal-mode summation for a spherical earth model with realistic atmosphere
TL;DR: In this article, a theory to compute seismograms and atmospheric disturbances such as ionospheric oscillations or pressure variations in a realistic spherical earth model with atmosphere is described, which is valid for a source located either in the solid earth or in the atmosphere.
Journal ArticleDOI
Scientific discovery with the James Webb Space Telescope
TL;DR: For the past 400 years, astronomers have sought to observe and interpret the Universe by building more powerful telescopes as mentioned in this paper, and these incredible instruments extend the capabilities of one of our most popular astronomy research areas.

Zonal mean properties of Jupiter's upper troposphere from voyager infrared observations
TL;DR: In this paper, a simple modeling of an axisymmetric circulation incorporating the linear damping of perturbations from a uniform state for both winds and temperature yields results that are consistent with observed thermal wind shears and with the vertical motion field.

Interaction of eddies and mean zonal flow on Jupiter as inferred from Voyager 1 and 2 images
Andrew P. Ingersoll,Reta Beebe,Jim L. Mitchell,Glenn W. Garneau,Gary M. Yagi,Jan-Peter Muller +5 more
TL;DR: Voyager 1 and 2 narrow-angle frames were used to obtain displacements of features at resolutions of 130 km over time intervals of 1 Jovian rotation as mentioned in this paper, where the velocities of the eddies varied with latitudinal coordinate y in the range from −3β to +2β, where β is the planetary vorticity gradient.

Numerical simulation of Jupiter's Great Red Spot
TL;DR: In this paper, the equations governing fluid motion in a model of the jovian atmosphere for a variety of initial conditions are solved numerically and a new prediction of its vertical structure is made.

Jupiter's Great Red Spot as a Shallow Water System
TL;DR: In this article, the authors derived the bottom topography of the Great Red Spot (GRS) using the GRS cloud-top velocity data, up to a constant that depends on the unknown radius of deformation.
