We have made the unhappy decision to cancel or postpone all events in March and April, including the Knavemsire star parties, because of the Coronavirus situation. This is purely a precautionary measure. Planned events for May onwards will be reviewed depending on the circumstances. Thank you for your patience.

Some events are subject to change due to unforeseen circumstances. Please check this page before setting off.

Our regular meetings are held at the Priory Street Centre in York. Click here for details.
The location of the regular Knavesmire star parties can be found here.

Our ‘Sister Observatory’, Lime Tree Observatory, also hosts a number of Public Astronomy Events, details of which can be found here.

Our public observing sessions are shown in green.

Voyager: An Interstellar Mission

The Voyager program consists of two robotic probes, Voyager 1 and Voyager 2, launched in 1977. As well as studying Jupiter and Saturn, they continued on to Uranus and Neptune. They now explore the outer boundary of the heliosphere in interstellar space and they continue to transmit useful scientific data.

The Rosetta Mission

Talk by Society member Dave Armeson

Rosetta launched in 2004, on a 10-year journey towards comet 67P/Churyumov-Gerasimenko. In November 2014, the mission deployed its Philae probe to the comet, the first time in history that such an extraordinary feat was achieved. Join us for an interesting exploration of this mission and its achievements.
