Astronomy Online

If you would like to receive a daily article about astronomy, email me at dbushn@swbell.net.  The articles come from various sources to which I subscribe, and have all been “down-edited” by the publishers to a level that we can all readily understand.  Recent articles have covered black holes, dark energy and matter, exoplanets, and neighboring galaxies.  A link to the source articles and related articles are usually included.
