In contrast, Immanuel Kant and Pierre de Laplace argued that planetary development was part of a normal process to be expected in the life of almost every star: they assumed the young sun was surrounded by a thin lens - shaped gaseous envelope (solar nebula) which later condensed into planets.

In his breathtaking conceptualization of planetary life, he saw the emergence of the human species and the subsequent globalization of the planet not in terms of the conquest of the globe by Christianity but as the logical consequence of an ongoing evolutionary process.

I maintained that, contrary to the commonly expressed or tacitly accepted view, the era of active evolution did not end with the appearance of the human zoological type: for by virtue of his acquirement of the gift of individual reflection Man displays the extraordinary quality of being able to totalize himself collectively upon himself, thus extending on a planetary scale the fundamental vital process which causes matter, under Certain conditions, to organize itself in elements which are ever more complex physically, and psychologically ever more centrated.

Even if we suppose that, by prolonging its existence on a scale of planetary longevity, the human species will eventually find itself with a chemically exhausted Earth beneath its feet, is not Man even now in process of developing astronautical means which will enable him to go elsewhere and continue his destiny in some other corner of the firmament?

First, planetary scientists suspect that cyanide was abundant on early Earth, deposited here by comets or created in the atmosphere by ultraviolet light or by lightning (once the atmosphere became oxygen rich, 2.5 billion years ago, the process would have stopped).

His team found that by tuning the model so that the pebble formation process takes a bit longer, there is more time for the large planetary embryos to interact with each other gravitationally.

The moon appears to be a tranquil place, but modeling done by University of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon's coldest craters through the process of sparking — a finding that could change our understanding of the evolution of planetary surfaces in the solar system.

By studying the jets from pre-planetary and planetary nebulae, Blackman and Lucchini were able to connect the energy and momentum involved in the accretion process with that in the jets; the process of accretion is what in effect provides the fuel for these jets.

By drilling into a circular ridge inside the 180 - kilometer - wide crater rim, researchers also hope to nail down the processes that form «peak rings»: hallmarks of the largest impact craters, which planetary scientists have seen elsewhere in the solar system but which erosion has erased from other big craters on Earth.

The observations reveal a new process by which the solar wind can penetrate deep into a planetary atmosphere.

The Mars Exploration Program studies Mars as a planetary system in order to understand the formation and early evolution of Mars as a planet, the history of geological processes that have shaped Mars through time, the potential for Mars to have hosted life, and the future exploration of Mars by humans.

The project may involve the following topics: — Interaction of the solar wind with magnetised and unmagnetised planets — Space weather forecasts — Numerical (HPC) and analytical modelling of MHD wave processes and jets in solar and astrophysical plasma — MHD wave observations and solar magneto - seismology — Application of advanced data analysis to solar system science — Physics of collisionless shocks (including planetary and interplanetary shocks)-- Analysis of multi-point measurements made by space missions, e.g Cluster (ESA), THEMIS (NASA), MMS (NASA)

However, a new study carried out by researchers from MIT and Purdue University seeks to challenge the established belief, asserting that rather than representing the kernel of planetary creation, that they are instead a by - product of the violent and often cataclysmic process.

Such braking is an important process because it assures a source of matter of relatively low angular momentum (by the standards of the interstellar medium) for the formation of stars and planetary systems.

At the booth, visitors were asking questions on the planetary formation process and distant regions of the universe to be explored by ALMA.

For example, the use of lightsails is currently in the process of being tested by another organization, the Planetary Society, with a publicly funded project called LightSail.

I was encouraged by your blog post citing Ilan Safit's thoughts on ecological citizenship as a precursor to planetary progress and at the same time want to respond to the suggestion that in Rio, the U.N. may have sacrificed its potential in shaping big ideas at the altar of practicalities and mechanical processes, important as they were.

Thus, some heat gets converted to kinetic energy, but that gets converted back to heat, either by viscosity or by thermally - indirect circulations that produce APE while pulling heat downward in the process (LHSO: Ferrel cell (driven by extratropical storm track activity), Planetary - scale overturning in the stratosphere and mesosphere (includes Brewer - Dobson circulation (I'm not sure if the whole thing is the Brewer - Dobson circulation or if only part of it is)-RRB-, some motions in the ocean; LVO: wind driven mixing of the boundary layer and of the upper ocean (though mixing itself tends to destroy the APE that the kinetic energy would create by forcing heat downward)-RRB-.

In essence, the Planetary Boundary analysis simply identifies Earth System processes that — in the same manner as climate — regulate the stability of the Earth System, and if impacted too far by human activities potentially can disrupt the functioning of the Earth System.

Comment: The sun is hypothesized to modulate planetary cloud cover by the heliosphere's modulation of the GCR and by the solar wind bursts remove of cloud forming ions via the process electroscavenging.

Our Planetary Boundaries research identifies that there are also other processes critical to the functioning of the Earth System that are so impacted by human activities that they, too, demand management at the global level.

Earth's Greenhouse Effect is described as all about radiant effects: Wiki: «The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions.

A˜m ≤ A˜m, max = A˜m, b, where A˜m, b is the amplitude reached by the planetary Rossby waves in the wave breaking process within the midlatitude belt Δ.

A blanket does not allow convection, whereas a planetary atmosphere does, so whichever analogy is used it is rendered inadequate by the processes involved in convection.

Outstanding questions include whether MJO events are commonly preceded by an earlier occurrence and, if so, what role the previous cycle plays in initiating a new MJO event; whether the processes that drive the moistening of the troposphere affect MJO behavior; and whether other large planetary waves — such as Rossby waves — can help trigger the next MJO.

None of this has any bearing whatsoever on mean planetary surface temperatures which are supported by the autonomous gravitationally induced temperature gradient which results from the process described in statements of the Second Law of Thermodynamics in which thermodynamic equilibrium evolves spontaneously.
