Astronomy (BUBL) - link to their Dewey 520 class

Astronomy (Yahoo)

Astronomy picture of the day (Robert Nemiroff (MTU) & Jerry Bonnell (USRA) - An object from the Universe is featured daily.  A high quality image (or animation) is presented and a clear explanation and commentary given, usually of one page length.  In addition there is an archive of all the objects featured so far.  Examples range from distant galaxies to the earth´s magnetic field.  Highly recommended.

Astronomy and Space Science (USGS) - resources arranged alphabetically, mainly to research institutions, observatories and university depts.

Expanding Universe - (created in conjunction with LibraryNet - a cooperative venture of Canada's Libraries and Industry, Canada) - this is a Dewey classified (like GEO.) large collection of links sitable for amateur astronomy.

The National Space Science Data Center (NSSDC) - This is NASA´s own data base which provides access to a wide variety of astrophysics, space physics, solar physics, lunar and planetary data from NASA space flight missions, in addition to selected other data and some models and software. NSSDC provides access to online information bases about NASA and non-NASA data at the NSSDC and elsewhere as well as the spacecraft and experiments that have or will provide public access data. NSSDC also provide information and support relative to data management standards and technologies.

Nuffield School Astronomy Programme (with Bradford Robotic Telescope) - this is for 7 - 12 year olds. It is included here for those who want to revise in an interesting way, some basic principles which we all get hazy on from time to time.
