" (...) Universe Today is different from your regular news website. Instead of writing in-depth articles, we just provide an overview, and links to sites where you can get more detail - from where the news first breaks to all the media coverage, and even related resources. We find all the stories, even the really obscure ones, and gather them together in one fast, easy-to-read newsletter (free of technical jargon). You only need to spend 10 minutes a day, and you'll be completely up-to-date on all the breaking news in the space industry.
So, you don't have to subscribe to several different sites to get comprehensive space coverage, just Universe Today.
To get the most out of Universe Today, subscribe to the email newsletter, which comes out every weekday. Follow the links directly from your email, and you don't even have to come back to the website." ... more

" Windows to the Universe is a user-friendly learning system covering the Earth and Space sciences for use by the general public. Windows to the Universe has been in development since 1995. Our goal is to build an internet site that includes a rich array of documents, including images, movies, animations, and data sets, that explore the Earth and Space sciences and the historical and cultural ties between science, exploration, and the human experience. Our site is appropriate for use in libraries, museums, schools, homes, and the workplace. Students and teachers may find the site especially helpful in their studying (and teaching!) Earth and Space sciences. Because we have users of all ages, the site is written in three reading levels approximating elementary, middle school and high school reading levels. These levels may be chosen by using the upper button bar of each page of the main site. " ... more

Started as a small college project, it evolved into a lifelong work, thanks to encouragement, help and advice from many of you. As content of this publication and its popularity grew, it required more and more time for development and, unfortunately, more cash to sustain ever-growing traffic. As a result, I turn to my readers, asking for sponsorship, in order to keep this site open to the public." Anatoly Zak ... more
