PLANET-PLANET SCATTERING IN PLANETESIMAL DISKS [PDF]
We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate the dynamics of marginally unstable systems of gas and ice giants both in isolation and when the planets form interior to a planetesimal belt.

Ontosonographic Maps: Toward a Theoretization of Soundscape Forms in the Anthropocene Epoch
This paper deals with the ways in which it is possible to conceptualize and map forms of soundscape in the epoch of the Anthropocene. After humans became a geological force, which is a role that used to be reserved for the planet itself, one can pose the

Dynamical Outcomes of Planet‐Planet Scattering [PDF]
Observations in the past decade have revealed extrasolar planets with a wide range of orbital semimajor axes and eccentricities. Based on the present understanding of planet formation via core accretion and oligarchic growth, we expect that giant planets often form in closely packed configurations.

The Astrobiology of Alien Worlds: Known and Unknown Forms of Life
Most definitions of life assume that, at a minimum, life is a physical form of matter distinct from its environment at a lower state of entropy than its surroundings, using energy from the environment for internal maintenance and activity, and capable of

Disc-planet, planet-planet, and star-planet interactions during planet formation
In this article we present results from three on-going projects related to the formation of protoplanets in protostellar discs. We present the results of simulations that model the interaction between embedded protoplanets and disc models undergoing MHD turbulence.

Specific Analysis of Web Camera and High Resolution Planetary Imaging [PDF]
Web camera is usually used for video communication between PC, it has small sensing area, cannot using long exposure application, so that is insufficient for astronomical application.

Environmental and economical ethics collide
In January 2020, during China’s COVID-19 outbreak, the NASA Earth Observatory captured aerial images indicating significantly lower emissions of nitrogen dioxide (NO2), a major air pollutant, across China’s mainland.[1] Scientists across the globe have ...
