Open Houses

Currently, due to COVID-19 precations, we are not doing Open Houses at the campus observatories. However, we have been hosting regular vitrual zoom events. Keep an eye out on our social media accounts for date, times, and more details! 

Virtual events from the Tortugas Mt. Observatory

Our Next Virtual Open House is April 23rd! - The NMSU Department of Astronomy will host a virtual online open house from the Tortugas (A) Mt. Observatory on Friday, April 23 at 8:00pm. The virtual event will be held via Zoom videoconferencing and will include a short virtual tour of the recently refurbished Tortugas Mt. Observatory, followed by some remote imaging, weather permitting, of the Moon and some conversation about observing, the Moon, and people involved in studying it! Registration is required to get the Zoom videoconferencing link.

Face-to-face events at the Tombaugh Campus Observatory

Face-to-face events have been suspended until further notice due to COVID-19

Our Open House events are held on Friday nights at the Tombaugh Observatory on the NMSU main campus (click here to see its location). They occur roughly once per month, often near the time of the first-quarter Moon from September through May, and occasionally during the summer. Each evening program includes a short presentation, followed by guided observing through telescopes. You may call 646.4438 for more information about the program for a specific month. Children are particularly encouraged to attend!

If the weather looks cloudy or stormy on the afternoon of an Open House Event, please call 646.6278 to confirm that the observatory will be open that evening. We cannot operate the telescopes under conditions of heavy clouds, high humidity, high winds, dusty conditions, or rain.
