You do not appear to have JavaScript (sometimes called "Active Scripting") enabled on your system. The Astronomy Pages use JavaScript for many functions such as animating diagrams, setting the text size, controlling the size of images and moving between pages. Thus, while it is possible to read the pages with JavaScript disabled, the "user experience" will be considerably impaired. |
I would thus encourage you to enable JavaScript before continuing. You can do this in Internet Explorer by selecting "Tools", and then "Internet Options..." from the drop-down menu. Click on the "Security" tab and then the "Custom Level..." button. Scroll down (quite along way!) until you see "Scripting" and then ensure "Active Scripting" is enabled. Confirm your change, then click on OK to complete the process. The procedure in Firefox is a little shorter - "Tools", "Options...", "Content" tab, ensure "Enable Javascript" is ticked, click OK. |
If you are concerned about the security implications of leaving JavaScript enabled when you access other sites, the same procedure can be used to disable it just before you leave my site. |
