Quantifying External Energy Inputs for Giant Planet Magnetospheres

Geophysical Research Letters
The long‐standing “energy crisis” at the giant planets refers to the anomalous heating of planetary thermospheres compared to the available energy from solar irradiance. The coupling between planetary magnetospheres and their upper atmospheres is thought

From Dawn till Dusk: How Light Reduces Martian Granular Slope Angles

The Planetary Science Journal
The maximum slope of a granular surface—beyond which particles start to move through avalanches—is determined by the balance of gravitational and interparticle forces and is independent of gravity when only frictional forces act between the particles ...

Codes in the Itineraries of the Planets of the Solar System

International Letters of Chemistry, Physics and Astronomy, 2014
Cosmos can be viewed from the perspective of the most advanced program, cyber and information systems and laws. Digital language Cosmos has a myriad of constants and variables, matrices, functions, vectors and determinants, which are coded information about the creation and functioning of our physical world in which we live. These are: Planetary orbits,

Laboratory Studies of Hypervelocity Impacts on Solar System Analogues [PDF]

, 2015
Impact cratering and asteroid collisions are major processes throughout the Solar System. Although previous collision-related impact investigations exist (Flynn et al. 2015, Holsapple et al. 2002 and Burchell et al.

An Agnostic Biosignature Based on Modeling Panspermia and Terraforming

The Astrophysical Journal
The search for a second instance of life is one of the greatest problems of modern science. Outside of creating an artificial origin of life on Earth, the primary targets for the search for life are planets inside or outside the solar system ...

CRIRES+ and ESPRESSO Reveal an Atmosphere Enriched in Volatiles Relative to Refractories on the Ultrahot Jupiter WASP-121b

The Astronomical Journal
One of the outstanding goals of the planetary science community is to measure the present-day atmospheric composition of planets and link this back to formation.

Passing Stars as an Important Driver of Paleoclimate and the Solar System’s Orbital Evolution

The Astrophysical Journal Letters
Reconstructions of the paleoclimate indicate that ancient climatic fluctuations on Earth are often correlated with variations in its orbital elements. However, the chaos inherent in the solar system’s orbital evolution prevents numerical simulations from

Giant planets: Clues on current and past organic chemistry in the outer solar system [PDF]

, 1992
The giant planets of the outer solar system - Jupiter, Saturn, Uranus, and Neptune - were formed in the same flattened disk of gas and dust, the solar nebula, as the terrestrial planets were.
