An animation of the eclipsing binary star Algol, assembled from 55 images of the CHARA interferometer in the near-infrared H-band, sorted according to orbital phase; because some phases are poorly covered, Algol B appears to jump at some points along its path around Algol A. A third star in the system is outside the frame.
Algol's characteristics have led to a star class and an apparent paradox being named after it.Animation: Dr. Fabien Baron; University of Michigan
