~ ~ ~

From January 2022 onwards…

This free event is one of the regular weekly public open evenings at Cambridge University’s Institute of Astronomy every Wednesday evening each year from October through to March. The entrance doors open at 18:45 with seating in the main lecture theatre on a first-come basis (there is also an overspill room).

These events offer a fantastic opportunity to look through the institute’s large Northumberland and Thorrowgood telescopes from within the observatory. Members from the Cambridge Astronomical Society will also be on hand with their telescopes.

Events go ahead no matter the weather, with an Astronomer from the Institute presenting a half-hour talk even if the evening is cloudy.  Most of the 30-minute presentations are suitable for children; however, they can leave if they become restless. Observing using the telescopes is subject to favourable weather conditions.

Please note that this event has already taken place on 01/12/2021

Event darkness

The Moon has a big impact on the visibility of celestial bodies in the night sky. Try to plan your stargazing when there is no bright Moon at night as this is when the skies will be at their darkest.

The below chart shows if and when the skies will be at their darkest during this event. Moonlight is shown in light yellow and the Sun's twilight in light blue. Midnight on the date shown is shown as a white line with sunset to the left and sunrise the next morning to the right. A black background with stars shows the best times for stargazing.
