Двойная популяционная объединенная схема основана на гипотезе двух родительских популяций: радиомощных радиогалактик типа FR II (справа), которые являются родителями всех радиоквазаров и некоторых объектов типа BL Lac, и радиогалактик умеренной мощности типа FR I (слева), которые являются родительскими по отношению к объектам типа BL Lac. vo @ sao.ru ( Oleg Verkhodanov ) .
... Bad Astronomy . ... Bad Astronomy : The seasons are caused by the change in the distance of the Earth to the Sun. ... The change in distance of the Earth to the Sun is a very minor player. ... Well, not completely wrong; certainly the Earth's distance from the Sun has something to do with the temperature, but it is a relatively minor effect. ... Basically, the temperature depends only weakly on distance changes; the temperature goes as the inverse square root of the distance of the planet to the Sun...

University Satellites and . Space Science Education . ... Two micro-spacecraft constellation with solar sails partially compensating the solar gravity allow their placement in the points along the Sun-Earth line behind the standard L1 point, i.e. further out from the Earth and closer to the Sun. The distances of the placement from the Earth and the base distances between such satellites depend on the ratios of their mass to the sail area. ...
... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...
