An informative medically oriented site. With the Voyager missions to the outer planets, the Hubble Space Telescope and the Galileo mission in progress, you would have to have your head in the sand, not to be aware of some of the exciting discoveries in space science and astronomy. To me this enlightening perspective of our insignificance in the scheme of things makes it all the more important to conserve and protect our planet and its biosphere. The internet is a huge repository of space images including the latest Hubble pictures, where you can see for yourself, these exciting discoveries. I hope you are excited about the Mars Pathfinder mission since it certainly is exciting to me.
Unpersoned probes are the way to go.
A couple of links allow you to personally experience and learn about this late breaking story. Another spiral imaged by the Hubble. I don't know why Hubble photos have chunks taken out of one corner. 4261 Hubble image of an accretion disk around a humongous black hole at the center of a nearby galaxy. The great spiral in Andromeda.
