There are only a few tickets left for our last Open Evening of the season, for the 17:30 slot on Friday 7th March.
The theme for this Open Evening is radio astronomy. The optical telescopes 🔭 will still be open, but we'll also be showing off our unique radio interferometer 📡

We've had a great time at @stalbanscathedral.bsky.social this week! We've been there with our mobile planetarium giving shows to local schools, and last night Dr. Emma Curtis-Lake gave a public lecture.
And now we're all back at the observatory for tonight's sold-out Open Evening!

Here's a quick view of Jupiter, taken during a student practical session last night 🔭
From left to right, you can see three of Jupiter's moons: Europa, Ganymede and Io.
You can also see Io's shadow on the face of Jupiter - it is the small dark spot near the upper right edge.

There is a lovely 22° halo around the Sun this morning. These halos appear when sunlight passes through hexagonal ice crystals in the atmosphere, and can often be seen in the winter months. 🔭

It's a planetary parade!
Throughout Jan and Feb, you will be able to see four planets lined up in the sky. With a telescope 🔭, you can also see Neptune and Uranus to make it six planets in a row!
This picture was taken with our Allsky camera just before 6pm (GMT) on Tuesday.

It’s hard to believe our newest 🔭 is now over three years old!
The 0.6m CDK24 is a favourite of our students, and one of the most popular attractions during our public open evenings. It’s easy to see why!
