– NAS


A huge in-depth public course by NAS with over 100 lessons all about the constellations. After completing this extensive course, you'll know the night sky inside-out – all the stars, constellation mythology and history, and the wonderful deep sky objects in each constellation.

This course is FREE to every logged-in user. So, click the Astronomy Courses menu and Register if you haven't already done so. Otherwise, click on The Constellations link and log in.  Each lesson has a quiz at the end to test your knowledge and is a great way to memorize lesson content. 

THE CONSTELLATIONS is a 'BIG' course and so requires web hosting, lesson updates, and maintenance to keep it live on the web. NAS simply asks for voluntary donations to chip in order to keep this mammoth work free for everyone. Thanks.  

Use the NAS 'Astronomy Courses' menu link to access the currently available courses. The Astronomy Fundamentals course is great for newcomers and urban-based amateur astronomers. In there, you can find out how light pollution affects your observations and what to do to minimize it. Get to know the Celestial Sphere and how the stars appear to be stuck to it. Understanding the celestial sphere helps enormously to navigate the night sky. Learn about the magnitude scale and how it's used to measure the brightness of celestial objects. And finally, get introduced to the constellations before diving into our main course.

Another course, which is ongoing, is called Exploring Physics, written from an electrical viewpoint. 

Elsewhere on NAS

The rest of this website (isn’t it nice to have an advert and pop-up free website for a change) is about the electric nature of the Universe.

The Electric Force - new astroscience

This website hopefully helps those who want to hear an alternative to mainstream astroscience. There aren’t enough of these kinds of websites around. Other sites to look at are:
