You can do this through its so called "ladder" method, which is great for newbies as it will help them ease into the game. When it comes to downloading WorldWide Telescope you should understand that it isn't free because you have to pay to download any software, especially from the developer. You don't need to worry though as there are lots of free trials for the software that you can get which includes downloads of games, maps, and videos too. Downloading WorldWide Telescope is easy to do and it's something you can do right in your Internet browser too.
Once you have downloaded the application, it's just a matter of opening it up and you'll be able to start exploring space. The main concept is to download the software then open it up and install it on your PC. When it asks if you want to install it, simply click the "Run" button to bring up the list of options. After clicking the add button, you'll see the WorldWide Telescope icon which will pop up in your system tray. As long as you're familiar with the Windows registry system, then you should be able to get to it easily after installing the application.
When you've downloaded the application and installed it, you should then click the download button in order to download the software and start using it immediately. Since it's a free trial, there won't be any charges to you. When the trial is over, you'll be prompted to pay a small fee to continue using the application, but you can always cancel it later on.
