Астрономия и Космос Небесные тела Звезды . А строномы объявили о новых исследованиях Полярной звезды на проходившей на прошлой неделе встрече Американского Астрономического общества в Рочестере, Нью-Йорк. Астрономы использовали оптический интерферометр (Navy Prototype Optical Interferometer - NPOI) в Аризоне, для того чтобы измерить размеры звезды, и обнаружили, что ее диаметр превосходит диаметр Солнца в 46 раз. Астрономам давно известно, что Полярная звезда относится к классу цефеид . ...
