Mendel Observatory

Wednesdays: Open to the Public

With the support of volunteers from the North Shore Amateur Astronomy Club, the observatory hosts public stargazing every Wednesday night, weather permitting, starting at dusk or 7:30 p.m. -whichever is later.

When special astronomical events of interest occur, such as a total lunar eclipse, the observatory often holds special viewing times.

Open to Merrimack 

This year we are also running student-led Star Parties at the Observatory. The event takes place roughly once a week, weather permitting, and the opening status each week can be found on the observatory Facebook page. Come and join us as we observe planets, double stars, the moon and deep space objects, such as galaxies and nebulas. The entire Merrimack community - students, faculty and staff - are welcome.
