Astronomical Resources on the Internet

Stellarium. N.A.A.'s Best Astronomy Websites. In an effort to recognize outstanding astronomy-related resources on the WWW, and to bring them to the attention of our website visitors, we, the webmasters of the Naperville Astronomical Association, have developed our Select Astronomy Site Award list.

N.A.A.'s Best Astronomy Websites

We consider these websites to be amongst the finest and most useful available to the astronomy enthusiast.

The Cosmic Distance Scale. The Cosmic Distance Scale By Maggie Masetti This feature will give an impression of how immense our Universe is by employing a method used many times in "Power of 10" films - that is, starting with an image of the Earth and then zooming out towards the furthest visible reaches of our Universe.

The Cosmic Distance Scale

This is not, however, an exercise in "powers of 10" - on the contrary, our goal is to show you astronomical distances without scientific notation. We instead focus on the large number of zeros that are in astronomical distances when we measure them with a familiar unit like the kilometer. The number of zeros increase with each zoom, though not at a constant rate. Why was this feature written? A note to teachers: This product passed the NASA Education Product review in 2010. Update!

What follows is a list of resources that excel in astronomy education.

Astronomy Picture of the Day's Educational Links

Each resource is distinctly different - they have been chosen to highlight a wide range of interests. We believe the list is topologically complete in that there are no publicly advertised astronomy resources on the WWW that cannot be found by following the internal links of these resources. The list is in alphabetical order, and is subject to change as the WWW, and our knowledge of it, matures. APOD in the Classroom.

The Andromeda Galaxy is the closest large galaxy to our Milky Way. Their apparent proximity if of course pure sleight of hand; the comet will be a mere 121 million miles (195 million km) from Earth on that date compared to Andromeda’s 2.5 billion light years.
