Resource type:
- classroom activity
Discipline:
- Earth science
Time: 90 minutes

Discipline:
- Space science
Time: 2-8 hours
Overview
The film LUMINOUS (now freely available through many libraries and the Kanopy platform) tells the story of astronomer Larry Molnar as he investigates a distant, double-star system, about which he makes a daring and explosive prediction. Interviews with Dr. Molnar’s diverse set of colleagues, collaborators, and skeptics highlight science as a community and intensely human endeavor, debunking the myth of the lone scientist conducting dispassionate research. The Luminous Science Education Toolkit provides classroom activities to support students' interpretation of the film.
