Privacy policy

We take your privacy seriously, however we do use cookies to personalise the content you see on this website. The night sky appears differently depending where you live, and so we need to make some estimate of your geographic location. In the first instance, we use the town where your computer's IP address is registered as an estimate of your likely location. Should you wish to receive more refined information, our location selection page allows you to voluntarily provide a more accurate location.

We do not store your geographic location on our servers, nor do we pass it to any third parties. However, we do store this information in your web browser, on your computer, in the form of cookies. Here, this information is stored for up to 28 days so that you do not need to reenter your location upon every visit.


We use Google Analytics to collect information about the usage of this site. We use the information we get from Google Analytics only to improve this website. For example, using cookies we can look at aggregate patterns such as the most popular pages of the website. We use such analysis to gain insights about how to improve the functionality of the website.


The servers used to host this website are expensive. As we do not make money in any other way, we use third-party advertisements to offset our hosting costs. Some of these advertisers may use technology such as cookies and web beacons when they advertise on our site, which will also send these advertisers (such as Google through the Google Adsense program) information including your IP address, your ISP, and the browser you used to visit this site. This is generally used for geotargeting purposes, or showing certain ads based on specific sites visited.

You can choose to disable or selectively turn off cookies or third-party cookies in your browser settings. However, this can affect how you are able to interact with our site as well as other websites. Alternatively, you may opt out of personalised advertising by visiting Google Ads Settings, or opt out of a third-party vendor's use of cookies for personalised advertising by visiting
