Summary
DescriptionArtist’s impression of eclipsing binary.ogv
English: This video shows an artist’s impression of an eclipsing binary star system. As the two stars orbit each other they pass in front of one another and their combined brightness, seen from a distance, decreases.
Русский: Это видео показывает представление иллюстратора двойной звёздной системы, находящейся в состоянии затмения. Когда две звезды вращаются вокруг друг друга, они проходят друг перед другом, и их совокупная яркость, видимая издалека, уменьшается.
