In March 1997, Marshall Applewhite directed the members of Heaven's Gate toward the ending his teaching had pointed to for decades. He and thirty eight followers ended their lives in a rented house in Rancho Santa Fe, California, thirty nine deaths in total, timed to the appearance of Comet Hale-Bopp.
Applewhite had taught that the comet was trailed by a spacecraft that would carry the group's souls onward once their bodies, which he held were merely vehicles, were shed. The deaths were not a departure from the movement's decades of teaching but its logical enactment, the "Next Level" transition he and Bonnie Nettles had described since the movement's founding in the early 1970s, carried out at the moment he identified as the right one.
The event drew wide public attention to a movement that had spent over twenty years in comparatively quiet communal life, celibate and disciplined, between periods of active recruitment. Applewhite died by suicide along with the followers he led, ending both his own life and, in practice, the movement he had co-founded.
What distinguishes the 1997 deaths from other tragic endings among new religious movements is how directly they followed from a specific, long-held teaching rather than from a sudden crisis: Comet Hale-Bopp's appearance was read as confirmation of a transition Applewhite had already spent decades describing to his followers.
