Other Events

Periodically throughout the year, the UNH Observatory hosts or is involved in other various special events at UNH and around the Seacoast. Be sure to check our website often to keep in the know!


​Sidewalk Astronomy

  • Join the UNH Observatory staff as we sporadically take to the streets of Durham to bring the skies to you.

    You may find us at one of our viewing stations on campus: in front of the Wildcat statue in front of the Whittemore Center; in the traffic triangle at the intersection of Main Street and Mill Road.

    These events are free and open to any interested in getting a chance to look at the night sky.

    These events are weather permitting and will not be held in the event of cloudy skies, rain, or snow.
