Event details

Part of our everyday experience is seeing the sky, filled with stars at night, clouded over or strikingly blue during the day. But why is the sky blue? And why does it sometimes look more white than blue?

Thinking about astronomy, we do not normally link it to understanding day time phenomena such as the blue in the sky. But there are many concepts we astronomers are familiar with that explain far more than just that but also the stunning colourful sunsets. We even use them to look for live on other planets. Join this month's open dome talk by Dr D Brown (NTU) on Blue Sky above – From sunsets to exoplanet atmospheres where he will take us from experiencing our atmosphere to analysing strange new world.

Booking is required for this event while attending in person. While attending, you consent to filming, photography, and sound recording – which may include you as a member of the audience – and its use in publication or advertising distribution, either printed or online, without payment or copyright.

This event is taking place as a hybrid event on NTU campus. This will allow a flexible way of attending. You are currently booking to attend in person (including tour and possible observations) and will need to purchase a £5 ticket for the event. If you are underage or an NTU student there is no charge.

You can also attend the virtual talk for free but would need to book the Open Dome VIRTUAL event to receive the link details.


The event will start at 8pm with Dr D Brown (NTU) talk Blue Sky above – From sunsets to exoplanet atmospheres. 

Refreshments will be offered from 7.45 pm in the CELS foyer. Afterwards, visitors will get a tour of the NTU observatory and the chance to see interesting objects in the Autumn sky using the observatory's telescopes, small telescopes and binoculars, if the weather allows it.

If the weather is not good, a small planetarium session will be offered in the observatory pointing out objects of interest.
