COSMOS Observatory Open Evening

Tuesday 5th October 2021 from 20:00pm to 22:00pm

COSMOS Observatory
Signal Row, St Martins, TR25 0QN, South West

Join the friendly and experienced team of astronomers at the Community Observatory St Martins on Scilly (COSMOS) and experience the truly wonderful dark skies above the Scilly Isles during this one of the facility’s regular Tuesday evening open nights.

From 17th May 2021 through to the end of October 2021 and depending on any Government restrictions regarding COVID the observatory will be opening its doors for small group visits. The 50-minute sessions start at 8 pm or 9 pm and must be booked in advance.

Whilst the skies may not get dark through Summer there will still be plenty to see, in particular, the planets Saturn and Jupiter can be observed in twilight skies, and therefore is very much worth a visit!

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.
