Because of the closure of Crown Mountain Park due to the fires, Saturday's New Moon Stargazer will be held at the Aspen Center for Physics, 700 W. Gillespie, Aspen, from 7 to 10:30 p.m.

This event is free, but organizers ask that attendees register at AspenScienceCenter.org in case there are any last-minute changes.

The event is put on by the Aspen Science Center.
