Well-Being on Planet Earth

Psychological Topics, 2009
The Gallup World Poll allows a look at how humanity is flourishing, based on the answers of survey respondents sampled from across the globe. Several conclusions are clear. First, how people are doing depends enormously on the society in which they live,

Contribution of the Moon-forming Impactor to the Volatile Inventory in the Bulk Silicate Earth

The Planetary Science Journal
The timing and mechanism by which the present-day inventory of life-essential volatiles hydrogen–carbon–nitrogen–sulfur (H–C–N–S) in the bulk silicate Earth (BSE) was established are debated.

The Hunt for Exomoons with Kepler (HEK): III. The First Search for an Exomoon around a Habitable-Zone Planet

, 2013
Kepler-22b is the first transiting planet to have been detected in the habitable-zone of its host star. At 2.4 Earth radii, Kepler-22b is too large to be considered an Earth-analog, but should the planet host a moon large enough to maintain an atmosphere,

Kepler-47: A Transiting Circumbinary Multi-Planet System [PDF]

, 2012
We report the detection of Kepler-47, a system consisting of two planets orbiting around an eclipsing pair of stars. The inner and outer planets have radii 3.0 and 4.6 times that of the Earth, respectively. The binary star consists of a Sun-like star and

A Survey of Multiple Planet Systems [PDF]

, 2009
As of August 2008, over 30 multiple exoplanet systems are known, and 28% of stars with planets show significant evidence of a second companion. I briefly review these 30 systems individually, broadly grouping them into five categories: 1) systems with 3 or more giant (Msini > 0.2 M_Jup) planets, 2) systems with two giant planets in mean motion ...

The Synergy of Direct Imaging and Astrometry for Orbit Determination of exo-Earths [PDF]

, 2010
The holy grail of exoplanet searches is an exo-Earth, an Earth mass planet in the habitable zone around a nearby star. Mass is the most important parameter of a planet and can only be measured by observing the motion of the star around the planet-star ...

Characterizing the purple Earth: Modelling the globally-integrated spectral variability of the Archean Earth

, 2013
The ongoing searches for exoplanetary systems have revealed a wealth of planets with diverse physical properties. Planets even smaller than the Earth have already been detected, and the efforts of future missions are placed on the discovery, and perhaps ...

How can economics contribute to environmental and social sustainability? The significance of systems theory and the embedded economy

Frontiers in Sustainability, 2022
Concerns relating to resource extraction, manufacturing, waste in our supply chains, along with increasing consumption and with their consequences for the planet, have, to a greater or lesser extent, begun to impact the ideological approach and the ...

Possible Motivations for Christians to Preserve Creation

Studia Ecologiae et Bioethicae
Three different aspects are presented that can motivate people to work for the preservation of creation. All three motivations are closely linked to Christianity, so that Christianity could become the key to solve the global problems.
