| | An Overview of the Solar System |
 | | The solar system consists of the Sun; the nine planets, more than 130 satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium. |  | | How common are planetary systems around other stars? |  | | This 'road map' of the solar system is the definitive guide for beginning planetary science. |

 | | Following a thematic progression, ranging outward from the Sun to other planetary systems, the Encyclopedia of the Solar System details the dynamics of motions and rotations, solar wind, planetary, geologic, and atmospheric conditions, as well as other processes in the formation of planets, satellites and the smaller bodies of our planetary environment. |  | | If you want to get a detailed, but not overly technical, overview of modern solar system science, this is the book for you. |  | | "The 56 contributors to this one-volume encyclopedia-all specialists in solar system science-describe the system from the galaxy inward to the sun and then outward through the planets....The audience the editors have aimed at includes teachers, students, advanced amateurs, astronomers who do not specialize in the solar system, and professionals in other scientific and technical fields. |

 | | Multiple systems should remain possible targets for any SETI strategy, with the understanding that there are added uncertainties about the possibilities for such systems. |  | | Here many multiple systems are integrated numerically on a computer, each system is evaluated for stability (usually qualitatively), and the pertinent parameters for stability are identified and quantified. |  | | These are not just binary stars, since at least a third of all multiple systems have three or more components (arranged in hierarchies of spacing such that any stable multiple system may be thought of as a set of binaries). |

| | Astrophysics Data System - Wikipedia, the free encyclopedia |
 | | The system uses data from the SIMBAD, NASA Extragalactic Database, International Astronomical Union Circulars and the Lunar and Planetary Institute to identify papers referring to a given object, and can also search by object position, listing papers which concern objects within a 10 arcminute radius of a give Right Ascension and Declination. |  | | The software which runs the system was written specifically for it, allowing for extensive customisation to astronomical needs which would not have been possible with general purpose database software. |  | | The scripts are designed to be as platform independent as possible, given the need to facilitate mirroring on different systems around the world, although the growing dominance of Linux as the operating system of choice within astronomy has led to increasing optimisation of the scripts for installation on this platform. |

 | | Gl 570D is widely separated from the main system and is indicated with an arrow. |  | | Planetary nebulae are formed as low-mass stars, like our Sun, reach the end of their lives and lose their outer envelopes (for this nebula, what are now the ring and halo structures) to the interstellar medium. |  | | The bright source within the bright elliptical ring is the hot central star of the planetary nebula, originally the core of the dying star, which will eventually become a white dwarf and cool off over billions of years. |

| | Epsilon Eridani |
 | | In September of 2002, a team of astronomers (including Cristiano Cosmovici of the Institute for Cosmic and Planetary Science) announced at the Second European Workshop on Exo/Astrobiology that they had detected water "maser" emissions from three of 17 star systems suspected of hosting planets, including Epsilon Eridani, using the 32-meter Medicina radio telescope near Bologna. |  | | Further reinforcing the indirect evidence of a planetary system around this star is the observed substructure within the dust ring and other asymmetries in the ring itself, all of which could be due to perturbations by more than one substellar companion, including one just inside the dust ring at an orbital distance of 30 AU. |  | | John Whatmough also has illustrated web pages on this system in Extrasolar Visions. |

 | | Renewable energy systems are considered to be environmentally friendly, and less disturbing than the traditional energy systems of the planetary and local ecological equilibrium since their material waste can be recycled, and their thermal waste energy is part of the natural climate forming heat. |  | | Systems belonging to first class are not predictable at all, those belonging to the second class are predictable only through an infinite computational capacity, and those belonging to the third class are predictable only through a trans-computational capacity. |  | | We have previously developed a conceptual framework for modeling complex problem-solving based on a systems model and are now researching the implementation of this model as an automated problem-solving tool on powerful state-of-the-art distributed computing systems. |

| | M57_Halo_Subaru Telescope |
 | | The name "planetary nebula" given to this class of objects is due to the fact that many of them appear disc-like, similar to how the planets in our Solar System appear when viewed through a telescope. |  | | Planetary nebulae like the Ring Nebula are often described as having a fairly simple structure, generalized as an elliptical shell. |  | | The shape of a planetary nebula depends on the distribution of the gases that were released, the strength of the ultraviolet radiation from the white dwarf, and the particular view we have of the nebula from our vantage-point here on the Earth. |

| | Identification and Analysis of Binary Star Systems using Probability Theory |
 | | The frequency of occurrence of binary and multiple star systems remains uncertain at the present time, and is a stumbling block to our understanding of the formation of stars, stellar systems, and planetary systems. |  | | Identification of physical binary star systems, with an estimated reliability of such identifications based on the theory of probability, is also important for current and future efforts to find binary star systems that are candidates for observations with the aim of determining their orbits and component masses. |  | | We will also present preliminary results from the application of these methods to Pulkovo's observation program of binary star systems, and outline how such methods might be applied to present and future high precision astrometric catalogues. |
