  Solar system - Wikipedia, the free encyclopedia
In broad terms, the charted regions of the solar system consist of the Sun, four rocky bodies close to it called the terrestrial planets, an inner belt of rocky asteroids, four gas giant planets, and an outer belt of small, icy bodies known as the Kuiper belt.
The solar wind extends to a point roughly 130 AU from the Sun, whereupon it surrenders to the surrounding envionment of the interstellar medium.
The edge of this bubble is known as the termination shock; the point at which the solar wind collides with the opposing winds of the interstellar medium.

 Solar power - Wikipedia, the free encyclopedia
Passive solar systems are systems that do not involve the input of any other forms of energy apart from the incoming sunlight, although (in the case of solar heat through windows) there may be draperies or panels used to reduce nighttime heat losses and thermostatically or manually operated vents (but not fans) to prevent overheating.
Solar hot water systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage, and a reservoir to stock the heat for subsequent use.
Solar cells, also referred to as photovoltaic cells, are devices or banks of devices that use the photovoltaic effect of semiconductors to generate electricity directly from sunlight.

 SOLAR CELL DEVELOPMENT AND PHOTOVOLTAIC PANELS OR ARRAYS AS USED ON THE SOLAR NAVIGATOR CATAMARAN
Solar cells or PV cells rely on the photovoltaic effect to absorb the energy of the sun and cause current to flow between two oppositely charge layers.
Spacecraft solar panels are constructed of these cells cut into appropriate shapes, protected from radiation and handling damage on the front surface by bonding on a cover glass, and cemented onto a substrate (either a rigid panel or a flexible blanket), and electrical connections are made in series-parallel to determine total output voltage.
Solar cells are the most expensive part of solar arrays, and arrays are often a very expensive part of the spacecraft.

 Healthopedia.com - Age Spots (Solar Lentigo, Solar Lentigines, Senile Lentigo, Liver Spots)
Age spots are flat, brown patches of skin that occur in irregular shapes.
Age spots are caused by an increased number of pigment-producing cells in the skin.
They are thought to occur in response to long-term sun damage and are associated with aging of the skin.

 Solar Age
Since the "ages" are a measurement of humankind's development, the dates are different in Europe and the Americas.
The Neolithic Period, or New Stone Age, refers to the second part of the stone age, and represents the time when stone and horn tools were refined by grinding and polishing.
Perhaps this method of introducing the concept of a "Solar Age" is a bit contrived but I had hoped it would place what I believe to be a monumental sociological transformation in historical context.

Two crucial issues in solar physics are nuclear reaction rates under solar conditions (Adelberger et al 1998; Junker 1998), and the opacity of the solar material (Iglesias and Rogers 1996).
The effect of the solar environment on beta decays is calculable, and has been found to be of modest importance (Bahcall 1997b, and references therein).
The solar neutrino problem alone was suggestive but not compelling evidence; the atmospheric-neutrino results clinched the case for non-standard neutrino behavior, and SNO confirmed that this solved the solar neutrino problem.

We derive stellar ages, from evolutionary tracks, and metallicities, from Strömgren photometry, for a sample of 5828 dwarf and sub-dwarf stars from the Hipparcos Catalogue.

We conclude that, although some of it can be attributed to stellar migration in the galactic disk, a large part of the observed scatter is intrinsic to the formation processes of stars.
