Astronomy for fun . Nightfall is an interactive application to simulate eclipsing binary stars, and to produce animated views, synthetic lightcurves and more. Takes into account the non-spherical shape of close binary stars, mutual reflection, and some other effects. Comes with documentation, on-line help, and lots of observational data of real binary stars.
Nightfall is a 1957 black-and-white film directed by Jacques Tourneur. The film, considered film noir, stars Aldo Ray, Brian Keith and Anne Bancroft. The low-budget film is remembered today for camera work by cinematographer Burnett Guffey.
